In this paper, a novel balanced T‐shaped printed antenna is proposed for 3G IMT2000 mobile handsets for the WLAN (IEEE802.11b) module. This balanced T‐shaped antenna is designed for microstrip‐feeding with balanced signals. The antenna was designed by merging an unbalanced T‐shaped antenna and a planar balun. A prototype of the antenna for operation at the IMT2000/IEEE802.11b bands is constructed and described. The measured and simulated return loss (in terms of the mixed‐mode S ‐parameters) and measured radiation patterns are obtained. The experimental results demonstrate the broad bandwidth and omnidirectional radiation performance of the newly developed antenna. © 2005 Wiley Periodicals, Inc.
