Abstract

A novel internal monopole antenna suitable for applications in AMPS/GSM/DCS/PCS quad‐band mobile phones is presented. The antenna comprises two orthogonal wideband monopole elements for operation at about 900 and 1850 MHz, covering the APMS/GSM (824–894/890–960 MHz) and DCS/PCS (1710–1880/1850–1990 MHz) bands, respectively. The quad‐band monopole antenna is also arranged in a compact structure such that it has a low profile (only 6 mm in this study) and protrudes from the top edge of the system ground plane of a communications device, thus making it very promising as an internal antenna, built‐in within the device's casing. © 2004 Wiley Periodicals, Inc.
