A new aperture‐coupled patch antenna is presented, in which the patch is surrounded by a conductor ground and the sides of the dielectric substrate are covered with conductor walls. The antenna was investigated numerically and experimentally. Result shows that the antenna has a bandwidth of about 28% (for | S 11 | ≤ −10 dB) centered at 10 GHz and an average gain of about 7.4 dBi over the operating frequency range, which are better than that of a conventional aperture‐coupled patch with the same parameters. At the same time, the antenna maintains a good radiation pattern. © 2003 Wiley Periodicals, Inc.
