PCB Antenna: The Ultimate FAQ Guide


I know you’re looking for a high-quality PCB antenna.

Or, you’d like to learn more about PCB antenna.

That’s why this guide explores all the basic and advanced concepts about the PCB antenna.

Let’s dive right in.

What is a PCB Antenna?

 PCB antenna

PCB Antenna

A PCB antenna is an antenna type that is furnished as a trace on your PCB.

Consequently, you find your PCB antenna takes a two-dimensional form, unlike the free-standing antenna.

You can fashion your PCB antenna in different shapes, such as a straight line or a curve.

The profile you adopt for your PCB antenna is determined by the available board space and antenna type.

Can you Furnish a PCB Antenna in Multiple Layers?

You make the PCB antenna by laminating it on the board surface during manufacture.

Unlike free-standing wired antennas that have a 3-D structure, this gives your PCB antenna a 2-D structure.

You can fabricate your PCB antenna such that it traverses multiple layers when using a circuit board with a multilayer configuration.

You can connect the PCB trace antennas in different layers by employing vias.

What is the Use of a PCB Antenna?

Antennas are useful in communication aspects where they function through the exchange of electromagnetic radiation in radiofrequency.

A PCB antenna is no different, allowing you an avenue for communicating wirelessly.

The performance capability of your wireless communication using the PCB antenna will depend on the system’s design.

You can use a PCB antenna with different communication modules at an operating frequency range between 0.7 – 2.5 GHz.

What are the Advantages of using a PCB Antenna?

You will find several benefits when you employ a PCB antenna.

  • The manufacturability of a PCB antenna is simplified, allowing you to save on costs.

You can fabricate a PCB antenna as a sub-process in the overall PCB manufacturing process.

  • You can also use the PCB antenna with the BLE function within the acceptable range of wireless usage.
  • The design of a PCB antenna is straightforward, with a small profile that you laminate to the board’s surface.
  • You can achieve a PCB surface design with a massive bandwidth when you engage optimal elements in your system.
  • You find using the PCB antenna to be suitable for a size restricted circuit boards over a wired antenna.

What are the Limitations of a PCB Antenna?

When using the PCB antenna, you find their use is limited in the following ways:

  • You lay the PCB antenna as a trace on the circuit board surface.

Consequently, you find your antenna design is limited to the available board area.

  • Since you are restricted with the board area, you find the PCB antenna and other board components are closely packed.
  • The PCB antenna is affected by the overall board design, which affects its performance.

Thus, when you alter your circuit board’s aspects, you are required to adjust your PCB antenna’s tuning.

  • When you compare the PCB antenna and the wire antenna, you find the latter is more efficient in its performance.

What Conditions Facilitate Good PCB Antenna Performance?

You lay the PCB antenna on the circuit board alongside other board populates as a trace pattern.

Nonetheless, you will note the PCB antenna is affected by the surrounding components and board structures.

However, the following conditions help in ensuring your PCB antenna exhibits up to par performance:

PCB Antenna

  • If your PCB has a small coverage of copper pour, it offers you adequate space for the PCB antenna.

Having enough board space to fashion your antenna will ensure you extract the best performance from your PCB antenna.

  • The proximity of the board populates to your PCB antenna negatively affects its performance.

Therefore, having circuit board features and electronic components located some distance from the PCB antenna will improve its performance.

  • When you furnish a PCB trace antenna, you subject it to the circuit board’s immediate environment.

Therefore, the performance of the PCB antenna will be affected by external factors affecting the circuit board.

How does the Ceramic Antenna compare to the PCB Antenna?

 Ceramic antenna

Ceramic antenna

 PCB Antenna

PCB Antenna

The ceramic antenna is fashioned as a chip-like component developed from ceramic-based materials used for wireless communication.

You attach this component to your PCB as you would any other electronic part.

You typically employ the ceramic antenna when you have space constraints on your circuit board.

You can find different ceramic antennas whose variations are based on their features rather than function.

Some of the ceramic antennas you can find are the inverted and planar inverted F antennas.

You note the ceramic antenna edges the PCB antenna on the following grounds:

  • You find ceramic antennas are distinguished from the PCB by being independent components that are fabricated separately.

Therefore, to create a connection between the PCB and the ceramic antenna, you attach it to the board.

  • You do not require to employ a large board area for your ceramic antenna, as seen with the PCB antenna.

Consequently, you can use the ceramic antenna where the size of the board is critical.

Additionally, using a ceramic antenna instead of a PCB antenna saves on much-needed board space.

As a result, you can use the extra board space to increase the board’s circuit density.

  • There are many different variations of the ceramic antenna that you can find. Furthermore, you can obtain these ceramic antennas in various sizes, depending on your application.
  • Since they are furnished separately from the board as individual components, you find ceramic antennas have fewer performance issues.

When you package ceramic components close to other board features, tuning issues are less pronounced in PCB antennas.

  • You find individual components are shielded from external disturbance resulting from factors in the environment and human contact.

Ceramic antennas are shielded by the ceramic casing, unlike the exposed PCB antennas susceptible to external disturbance.

  • You can carry out tuning procedures and tests on the ceramic antenna with ease without undertaking sophisticated measures.

Tuning PCB antennas is a complicated procedure that requires you to undertake expensive maneuvers such as design alterations.

  • When you need to change your ceramic antenna’s design, you have a more straightforward implementation path, unlike with PCB antennas.

What are the PCB Antenna Parameters to Consider?

For the PCB antenna, you find the following essential considerations that influence its performance.

  • The length of the antenna
  • The antenna feed
  • The size and shape of the PCB’s ground plane and the signal’s return path.

How is the Wire Antenna different from the PCB Antenna?

 Wire antenna

Wire antenna

Antennas are used to capture radio frequency communication and are typically conductors whose length is a quarter of the wavelength.

Consequently, you find the length of an antenna will tell you what frequency is communicated.

The wire antenna protrudes from the PCB into space, unlike the PCB antenna, which you laminate onto the board surface.

You find its length is from a ground plane position while it is attached to a transmission line.

You find the wire antenna has a 3-D form by extending into free space, unlike the PCB antenna’s 2-D structure.

Therefore, you will achieve better performance in terms of communication ability and radiofrequency range.

You can furnish the PCB antenna in different shapes, such as a straight line, a curve, or a circular pattern.

You can also present your wire antenna straight or in other forms, such as a loop or as a helix.

Printed circuit board antenna

Printed circuit board antenna

How do you Select an Antenna?

You are provided with three distinct antenna types that you can employ for your application needs.

You have the choice of a PCB antenna, a wire antenna, and a chip antenna.

In making your antenna choice, you consider the following factors:

  • The nature of the application of the antenna. You find this alludes to where you will use it, such as a Bluetooth Low Energy application.
  • The size of your printed circuit board. Where you have space constraints, you are well-positioned to use the chip antenna.
  • The cost of acquiring a particular antenna.

For instance, you have more associated costs when using the chip antenna than the wire or PCB antenna.

  • It is useful to know the range of RF communication you intend to work with.

You find the nature of your application will determine the range of communication.

When you have an application employing Bluetooth low energy, your range needs will barely exceed ten feet.

Heavier applications such as remotely controlled audio functionality will require at least twenty feet for closed environments.

What are some of the PCB Antenna Parameters?

When working with a PCB antenna, specific vital parameters influence the antenna’s performance.

· Efficiency of Radiation

When using a PCB antenna, not all of the energy is reflected.

You establish some of the non-reflected energy is released as heat registered as a thermal loss by the PCB antenna.

You use the term radiation efficiency to describe the thermal loss resulting from the energy reflection process.

You find this loss to result from the dielectric substrate’s loss alongside the conductor loss.

When you have a hundred percent radiation efficiency, it signifies the total radiation of the non-reflected energy.

The thermal loss is directly related to the size of the circuit board.

· Bandwidth

The frequency values at which the PCB antenna responds to reflect its bandwidth.

You find the bandwidth of a PCB antenna also influenced by its matching with the transmission line.

However, the matching is pegged to the relevant band of the application.

For instance, you find the Bluetooth Low Energy application has an appropriate band interval between 2.4 and 2.8 GHz.

You are better off employing a wide bandwidth for your PCB antenna.

You find having wide bandwidth of water down detuning effects.

When detuning, factors external to the PCB antenna present during operation can affect the process.

· Radiation Pattern

The radiation pattern of a PCB antenna is descriptive of the direction of your antenna’s radiation.

This is to say that your PCB antenna’s radiation pattern highlights the radiation levels in given directions.

Knowing the directional feature of your PCB antenna’s radiation helps you to align the antenna when in use effectively.

Some antennas can exhibit equal radiation at right angle planes to the axis of the antenna.

· Return Loss

The matching level between your PCB antenna and transmission line value is provided for by the return loss.

Usually, the transmission line will have an impedance value of fifty ohms, but not always.

The return loss indicates the reflection of the incident power due to mismatching by the PC antenna.

An infinite reflection loss highlights an ideally matched PCB antenna to the transmission line.

An ideal match between the PCB antenna and the transmission line achieves total energy radiation devoid of losses through reflection.

The return loss, as well as its converse value, S11, is expressed in decibels.

· Gain

While you find the isotropic antenna exhibits all-directional uniform radiation, many other antennas deviate from this working.

Thus, when you use a non-isotropic antenna, gain helps define the radiation in a particular direction, unlike the isotropic antenna.

What is Tuning when using a PCB Antenna?

When you tune a PCB antenna, you set it such that the antenna is recipient to maximum power.

This is done as the transmission is positioned over the length of the frequency band.

Tuning the PCB antenna will involve setting the return loss for each frequency band at a determined value.

Typically, you find this value to be equal to or greater than ten decibels.

You transfer maximum power to the PCB antenna when the input and output impedance match.

When you tune the PCB antenna, you match the impedance to the transmission line of the antenna.

What are the Types of PCB Antenna available?

You find different companies furnish their PCB antennas in various designs and forms.

Thus, you can encounter many different types according to the manufacturers.

You find two types with common usage in the industry and are employed mainly in Bluetooth Low Energy applications.

These antennas are low cost with a simple design allowing you performance stability at low-value frequency ranges.

· Meandered Inverted-F antenna (MIFA)

You find the MIFA useful in applications where you have limited circuit board space.

A common area of application is in human interface devices, for instance, wireless computer peripherals like the mouse.

· Inverted-F antenna (IFA)

You use IFA where the dimensional requirements of the PCB antenna are dissimilar.

A case in point is the circuit board antenna for the heart monitor.

Can the PCB Antenna be Laminated on a Two-sided Board?

You implement the PCB antenna on a circuit board as a trace conductor.

Usually, you find the trace is provided at a given width that varies with the PCB layer stack-up.

You can find a PCB antenna fashioned on a two-layer stack-up, primarily when used for small circuit boards.

The two layers are the top and bottom layers, which are typically fabricated over an FR-4 substrate.

You have the antenna trace on the top layer resulting in the layer being referred to as the antenna layer.

For the bottom layer, you use it as the ground plane for the radio frequency signal.

What is the Effect of a Ground Plane on the Performance of a PCB Antenna?

You find PCB antennas are affected by the size of the radio frequency ground signal.

However, you find that a ground plane’s role is essential for the effective working of a PCB antenna.

You can design the PCB antenna to be a resonator with a frequency-dependent on inductance and capacitance values.

Here, you note your resonator’s frequency reduces when you have an increase in either the inductance or capacitance.

When you employ a large ground plane, the operative capacitance of your PCB antenna increases.

As a result, the frequency value of your resonator decreases.

Furthermore, you will realize that employing a ground plane will help you achieve an improved return loss.

This is common where you have small circuit boards with space constraints that discourage clearance for the ground.

Does having a Casing Affect a PCB Antennas Performance?

You can determine the effect of enclosing a PCB antenna in a casing by subjecting it to a test.

Here, you enclose the PCB antenna and identify its return loss value while deriving its radiation pattern.

You observe the following when you enclose a PCB antenna:

PCB Antenna

PCB Antenna

  • You note a reduction in the resonant frequency for an enclosed PCB antenna.
  • You find the frequency adjustment for resonance to be between one and two hundred megahertz.

You find tuning efforts are necessary to return your PCB antenna to the required frequency band after casing.

What are the Guidelines when Placing PCB Antennas?

You find the guidelines for placing PCB antennas to be specific to the enclosure and the ground plane.

Some of the guidelines are listed as follows:

  • It would help if you positioned the PCB antenna well apart from other circuit board elements to prevent interference.

You can fit the PCB antenna at one board end separated from the PCB circuit features.

  • You need to use the ground design issued by the manufacturer of the PCB

You find many PCB antennas to be of monopole derivation requiring sturdy ground construction for effective performance.

  • You should isolate the PCB antenna from other circuit features such as electrical components.

This ensures you prevent interference in radio frequency communication with the PCB antenna, which will require consistent retuning.

  • Your PCB antenna should be kept away from plastic features as they subject it to a high-value dielectric constant.

You observe that the dielectric constant value for plastic is higher than that of air.

  • You need to ensure the trace for your PCB antenna is not traversed by cables, such as battery links.
  • Additionally, your PCB antenna should not be entirely enclosed in a metal housing. Where a metallic housing is employed, it should not be used over the PCB antenna.
  • When orienting the PCB antenna, you should match it with the eventual products to maximize the radiation pattern.
  • You need your PCB antenna to have no ground below it with enough clearance provided at a minimum breadth.
  • The impedance values of the PCB antenna can vary due to other board connections and circuit features.

Thus, you will need to provide an elaborate network for matching your PCB antenna.

  • PCB antenna matching requires the use of different values in the construction of a network. You need to use the relevant value highlighted in the datasheet for your manufacturer for your matching works.

How does Impedance Influence the RF Design of a PCB Antenna?

You find the impedance of a PCB antenna’s radio-frequency circuit is essential in influencing its performance.

When you measure a PCB antenna’s load impedance at different tracepoints and low frequencies, you find it unchanging.

Additionally, you find impedance is unaffected by the trace parameter of width or evenness.

However, when you measure the impedance at different load points in high frequency, you notice changes.

The difference you observe in impedance values is also influenced by the trace dimensions for the RF circuit.

You also find the type of substrate to be influential.

What are Transmission Lines in PCB Antennas?

A transmission line is an instrument that you use to transfer electromagnetic signals over a distinct pathway.

Transmission lines on a circuit board can be coaxial cables, the radio-frequency trace, and waveguides.

You find transmission lines are used for the radio-frequency traces in the form of microstrips or waveguides.

For a transmission line, you find its characteristic impedance as an essential parameter.

The characteristic impedance is the altitudinal voltage and current ratio of a wave formation in a transmission line with no loss.

You find this property ensures no energy dissipation by the transmission line and, therefore, no loss.

What is the Difference Between Insertion Loss and Return Loss in PCB Antennas?

You find the insertion loss and the return loss are essential values when setting up a PCB antenna’s matching network.

The return loss is a ratio you obtain when you relate incident power and reflected power.

Contrarily, insertion loss is power loss experienced in a circuit during inter-stage transfer and expressed as a percentage.

Typically, you expect a total energy transfer between stages with no reflected power and subsequently no insertion loss.

Furthermore, you will observe a return loss infinity in an instance where you have no insertion loss.

Practically, however, you are bound to experience some return loss contingent to the application, usually not exceeding thirty decibels.

What Factors Affect the Characteristic Impedance in a PCB Antenna?

Characteristic impedance is a vital PCB antenna parameter that significantly influences performance.

You find the point impedance on a radio-frequency trace is subject to its characteristic impedance and load distance.

The following factors, on the other hand, influences the PCB antenna’s characteristic impedance:

  • The material used for the PCB.
  • The substrate thickness.
  • The trace width and thickness.
  • The space allowed between the radio0frequency trace and the ground plane.

Why is a Matching Network Important for your PCB Antenna?

You set up a matching network to reconcile the impedance values at any point to the RF trace’s characteristic impedance.

Matching impedance values for the load and source is vital in ensuring the transfer of maximum energy.

You observe the impedance values on a circuit vary with the position of the load.

Furthermore, when you attach components to the circuit, their positioning will affect the impedance values and match efforts.

You also note that your circuit’s impedance values can change due to the presence of stubs.

These stubs will take the role of capacitors or inductors on your circuit, effectively altering the impedance values.

Therefore, you find these stubs can jeopardize the matching efforts if their presence is undesired, occasioning a reduced performance level.

However, some stubs are deliberately included in circuits such as RF circuits with narrow bands.

You can measure how effective your matching network is by establishing the return and insertion loss values.

Ideally, for an effective matching network, the return loss assumes the value of the insertion loss.

That’s it.

But, I know probably, you could be having more questions about PCB antenna.
