Design of a weathercock‐shaped microstrip patch antenna with a T‐slot for the Hiper‐LAN band

Abstract

In this paper, a weathercock‐shaped microstrip patch antenna for application in a Hiper‐LAN is designed and fabricated. To obtain sufficient bandwidth when VSWR < 2, the T‐slot is inserted in the patch and a coaxial‐probe source is used. The measured result of the fabricated antenna is 350 MHz or about 7.62% bandwidth when VSWR < 2, referenced to the center frequency, with gain of 5.25–6.70 dBi. The experimental 3‐dB beam width is seen to be broad across the passband for the azimuth and the elevation at 80.32° and 83.88°, respectively. © 2006 Wiley Periodicals, Inc.
