Abstract

This letter presents a novel shorted patch antenna for applications as internal mobile handset antennas. Instead of a conventional simple ground plane, the proposed antenna uses an L‐shaped ground plane, which effectively decreases the antenna's backward radiation and enhances the antenna gain. A prototype of the proposed antenna suitable for operating in the UMTS (1920–2170 MHz) band has been constructed, and experimental results are presented. The constructed prototype occupies a small volume of 30 × 17 × 7 mm^3^, which makes it suitable to be employed as an internal mobile handset antenna, and shows a peak antenna gain of about 3.5 dBi, with gain variations less than 1.2 dBi for frequencies within the UMTS band. © 2002 Wiley Periodicals, Inc.
