The L‐shaped probe is shown to be an excellent feed for the thick circular patch antenna. The substrate used is a foam layer of thickness about 10% of the operating wavelength. An impedance bandwidth of 24% and an average gain of 7.5 dBi are achieved. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 256–257, 1999.
