A small and low-cost planar inverted F-antenna solution applicable in many different environments is presented. Attention is paid to the immunity of the antenna input impedance to the platform. A theoretical study of the effects of the platform is presented by analyzing the decay of surface currents caused by vertical and horizontal point sources. The design and measurement results of an example platform tolerant PIFA are reported and discussed.
