We present an aperture‐coupled microstrip antenna for mobile applications. The antenna is investigated experimentally and its measured impedance and radiation properties are verified by a cavity model. A theory for an aperture‐coupled microstrip antenna at higher‐order modes is developed by application of the cavity model, and the characteristics at the TM 11 mode are reported. A maximum bandwidth of about 8% is achieved. The investigations may be useful for low‐angle scanning applications using conical beams. © 1996 John Wiley & Sons, Inc.
