A novel coaxial‐fed E‐shaped microstrip patch antenna is proposed in this paper. The proposed antenna is found to have a much broader impedance bandwidth as compared to the conventional U‐slot antenna. An impedance bandwidth of about 33.8% is achieved for the proposed E ‐plane antenna. Through the use of a washer on the proposed antenna, the probe inductor is compensated, and an impedance bandwidth of 40% is thus obtained. The E ‐plane radiation pattern for both the proposed antenna and the one incorporated with the washer remains relatively constant through the band. A comparison between the U‐slot antenna and our proposed antennas is made in the paper. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 27: 348–352, 2000.
