✦ Synopsis

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 left‐hand 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. © 2005 Wiley Periodicals, Inc.
