This article describes the design of a compact, circular polarized (CP), nearly square patch antenna using an offset microstrip feed and operating at 2.45 GHz. The effect of the offset on the perturbation segment and the design of a simple matching net...
In order to obtain circular polarization, a dual feed can be used to excite a square patch to generate two fundamental modes, TM 10 and TM 01 , radiating at the same frequency. To meet the necessary conditions for circular polarization, the two modes must be equal in magnitude...
