摘要：

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. (c) 2005 Wiley Periodicals, Inc.
