Abstract

Novel compact circular polarization (CP) designs of a single‐feed triangular microstrip antenna with a triangular slot or an inverted triangular slot are proposed and experimentally studied. For the design with a triangular slot, CP operation can easily be achieved by inserting a slit with a length about 24% of the slot's side length at the center of the inner bottom edge of the patch. As for the design with an inverted triangular slot, the insertion of a slit with a length about 12% of the slot's side length can result in CP radiation. Results also indicate that with the triangular slot embedded in the patch, the proposed CP design can have an antenna size reduction of about 30% as compared to the regular‐size CP design using a simple triangular patch. © 2002 Wiley Periodicals, Inc.
