Ceramic Planar Inverted F Antennas, or PIFAs, offer a distinct advantage over the monopole design by offering the greatest RF gains and highest radiation efficiency, and are more resilient to hand-loading effects. Ceramic PIFA are engineering intensive, requiring an experienced RF engineer to design-in the antenna. Due to the high dielectric constant ceramic used, the ceramic PIFA is best suited for handheld applications and offers one of the smallest footprints available on the market.
