Abstract

A circular patch antenna tuned by a ferrite post is presented. The DC-biasing magnetic field is assumed perpendicular to the patch and the ferrite losses are taken into account. Both right- and lefthand circular polarizations are considered. The "perfect magnetic walls" approximation is employed and the resulting closed-form expressions can be used in the design of patch antennas. Also, this approximate but analytical study offers a clear physical insight with regard to the ferrite effects on the patch antenna's resonance characteristics.
