FABRICATION AND MEASUREMENT OF TRIANGULAR-SLOT ANTENNA FOR TRIPLE-BAND (2.4/5.2/5.8 GHz) ANTENNA WITH RECTANGULAR TUNING STUB

摘要

In this paper, a novel design of a triangular-slot antenna with rectangular tuning stub for 2.4/5.2/5.8 GHz triple-band applications is presented. The prototype consists of a triangular slot and rectangular tuning stub. Results show that the impedance matching of the proposed antenna is greatly affected by the feed gap width. Experimental results indicate that the impedance bandwidth (VSWR 1:2) of the proposed antenna is about 423 MHz for the 2.4-GHz band and 1.92 GHz for the 5-GHz band. The simulated and experimental results for the return loss, radiation patterns, and gains are presented and discussed.
