Abstract A new design of a circular patch antenna with an impedance bandwidth greater than 25% and a peak antenna gain about 8.3 dBi is presented. The circular patch antenna has a thick air substrate, and a pair of wide slits are cut in the circular patch to facilitate the antenna's impedance matching. The circular patch is supported by a conducting post, which is also connected to a 50 Ω microstrip feed line. The ground plane of the microstrip line also serves as the ground plane of the circular patch antenna, and the substrate of the microstrip feed line and the circular patch are on the same side of the ground plane. Details of the antenna design and experimental results are described. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 327–328, 2000.
