Abstract

A novel trident-shaped dual-band CPW-fed monopole antenna for PCS/WLAN applications is presented. By inserting two pairs of symmetrical strips in the middle strip of the trident-shaped antenna, dual-frequency operating bands with 10 dB return-loss bandwidths of 33.7 % , ranging from 1.80 to 2.53 GHz, and of about 1100 MHz centred at 5.5 GHz have been achieved. They cover the required bandwidths of the PCS band (1.85 1.99 GHz) and WLAN bands (2.4 2.484 and 5.15 5.825 GHz). Also, good radiation patterns, and 3.6 and 9.1 dBi peak antenna gains for the lower (2.2 GHz) and upper (5.5 GHz) bands have been measured.
