Abracon | Why Planar Inverted-F Antennas?

The Advantages of Planar Inverted F Antennas (PIFA)

What are PIFAs?

PIFAs are a special case of monopole antennas that originated from the inverted-F antenna design. Unlike traditional monopole antennas, PIFAs have a top plate instead of a single wire. This top plate can be modified to change the size of the antenna, which makes it possible to create smaller antennas. The antenna is positioned parallel to the PCB and requires limited space, making it an ideal choice for compact devices. The short circuit arm acts as impedance matching for the antenna, improving the radiation efficiency.

Advantages of PIFAs

PIFAs have a moderate to high bandwidth, an omnidirectional radiation pattern and mixed polarization, making it a versatile choice for various wireless communication protocols and frequencies. Another significant advantage of PIFAs is their robustness towards changes in the surrounding environment. Unlike other antenna types, PIFAs continue to radiate efficiently, even in close proximity to metal. This feature makes these antennas a suitable choice for mobile and wearable devices that are used in ever-changing environments.

PIFAs are an innovative antenna type that offers a balance of size, performance, and stability for various wireless communication needs. If you are looking to integrate PIFAs into your device design, Abracon is a leading provider of these components, offering a range of options to meet your specific requirements.
