The high‐performance characteristics of an annular‐ring‐coupled shorted circular microstrip antenna are presented. This new geometry offers larger impedance bandwidth with a good return loss characteristic, a higher gain and radiation efficiency, and most importantly, a pattern characteristic with lower cross‐polarization levels in the H ‐ as well as E ‐planes. This new structure is investigated both theoretically and experimentally. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 386–388, 2001.
