A compact wideband planar diversity antenna for mobile handsets

Abstract

Abstract A novel compact wideband printed diversity antenna for mobile handsets is presented. The antenna comprises two back‐to‐back G‐shaped monopoles placed symmetrically with respect to a T‐shaped and dual inverted‐L‐shaped ground plane. The measured results show that the proposed diversity antenna operates in a very wide bandwidth of 420 MHz starting from 1890 to 2310 MHz covering the UMTS band (1920–2170 MHz) with acceptable isolation. The antenna can provide pattern diversity to combat multipath fading. © 2007 Wiley Periodicals, Inc.
