✦ Synopsis

Abstract

A shorted patch antenna suitable for application in the sliding mobile phone as an internal antenna is presented. The shorted patch antenna is mounted at the bottom end of the lower ground plane of the mobile phone, and can generate a wide operating band for UMTS (1920–2170 MHz) operation in the talk condition (the mobile phone is slid open for use). In addition, when the mobile phone is in the standby condition (not slid open), the antenna can still provide acceptable impedance matching for operating frequencies over the UMTS band. Details of the antenna design are described, and experimental results of a constructed prototype are presented. © 2006 Wiley Periodicals, Inc.
