Product List
Of the many benefits of a loaded PIFA antenna structure, there are some primary benefits. Due to the combination of the ceramic antenna element and the PCB resonance radiation, they are capable of achieving an extremely good efficiency number when properly implemented, up to 90%. The same combination also creates a close to omni-directional 3D radiation pattern. Another benefit of the PIFA is the high immunity to frequency detuning due to user tissue (body, hand, head) and surrounding mechanics.
