FPC is an alternative to chip antennas and is an interesting option for specific embedded designs.
FPC antennas are thin, typically only 0.15 mm, with a peel-off strip and a bonding area that allows them to be secured inside small electronic devices in a variety of configurations. They are supplied with a cable and a connector for fixing them to the bottom covering or housing of the manufacturer's electronics. An FPC is very light, probably less than 0.5g.

This picture shows the FPC antenna with cable and I-PEX connector.
Advantage: no ground problems
FPC work differently than surface mount device (SMD) chip antennas. The SMD antenna is radiated using the installed ground plane, and its working principle is reciprocation. A dipole antenna uses two radiators, the length of each radiator is related to the wavelength of the frequency used by the antenna. Embedded antennas have a heat sink within their mass, and they use an area on the PCB as their counter plane, often referred to as the ground plane.
For SMD antennas, the length of the ground plane is directly related to the wavelength of the antenna. The correct ground plane length must be provided in the design so that the antenna can operate with good efficiency.
FPC antennas are different in this - they don't need a ground plane to radiate. Therefore, they allow designers more freedom in arranging the components in the circuit in the design.
However, it is important to remember that the coaxial cable becomes part of the antenna. Therefore, when designing the routing of the cable, care should be taken to keep this part of the antenna away from other components that may generate noise and interference.
Place
Because the ground plane is not a design consideration for FPC antennas, the size of the host PCB is not a factor as it is for SMD or chip antennas. However, the placement of FPC antennas still needs to follow some basic rules, as most antennas are sensitive to the environment.
The antenna will radiate in six spatial directions (Figure 2). Ideally, at least three to five of these directions should be clear of obstructions, which will allow the antenna to work efficiently. For other directions with obstructions in the radiation path, there should still be a minimum gap, which will be defined in the antenna manufacturer's datasheet.
Figure 2,There are no obstacles in the four spatial directions where the antenna is placed
The plastic casing of the device will not act as a barrier unless the material from which the casing is made is glass-filled, or has been painted with metallic paint. Metal objects and components close to the FPC antenna, such as data lines and printed circuit boards (PCB), are often the culprits blocking the signal.
Orientation of FPC
The shape of the device will determine the ideal orientation of the FPC relative to the host PCB. The location of the antenna relative to the PCB will depend on the proximity of the ground (Figure 3).
Figure 3. The figure depicts three common configurations of FPC on a host PCB.
Whichever option is chosen, distance (d) becomes a critical dimension in the design. This will be specified in the antenna manufacturer's data sheet.
Device Integration Example
Figure 4 shows an integrated example of an FPC antenna. The main components of the device are in an outer box. The FPC has been adhered to the inside of the plastic housing of the device, and the cables are routed along the PCB so that they do not interfere with any other components. In this case, the FPC is placed on the same plane relative to the PCB. Due to the ultra-thin design of the device, this is the best location for the antenna.
Figure 4. Here, the FPC is integrated into a narrow device
The I-PEX cable for the antenna connects it into the design. The characteristic impedance of all transmission lines within the product is designed to be 50Ω and should be kept as short as possible. All other parts of the RF system, such as transceivers and power amplifiers, should also be designed with 50Ω impedance.
We recommend using a commercial RF design package to create the transmission line layout, taking into account PCB thickness, copper thickness, and dielectric constant. The program will calculate the recommended width of the transmission line, and the appropriate space between the reference ground planes on either side of the antenna feeder to maintain a 50-Ω system impedance.
Are FPC Antennas Right for Your Design?
For small PCBs, SMD antennas may be the most obvious choice, but FPC antennas are widely used in space-hungry applications.
Off-the-shelf FPC antennas are not recommended for the smallest devices, but there are many applications where FPCs work well. They are a particularly useful option for designs where ground plane length and space are constrained.
