Abstract

A small size circularly polarized (CP) microstrip patch antenna is presented. The proposed single-feed circularly polarized design is achieved by adding eight U-shaped tails at the patch edges. Five rectangular slots and four L-shaped slots are also inserted in the patch. The patch antenna is a one-layer structure. Our design reduces the projection area of the antenna by 75% in comparison with a conventional small patch antenna. Details of the design of this circularly polarized patch antenna are described. Experimental results of its performances are presented and discussed.
