A slot‐fed U‐slotted patch antenna is developed as an aperture‐coupling structure, and is compared to the existing feed types. Its wideband mechanism is explained, and its samples for Ku ‐ and S ‐bands are designed, simulated, and tested. A bandwidth of about 42% for VSWR less than 2:1; and 30.1% for −3 dB peak gain are obtained. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 378–381, 1999
