✦ Synopsis

Abstract

A low‐profile internal monopole antenna has been proposed for multistandard mobile phones. The proposed antenna operates at GSM (880–960 MHz), DCS (1710–1880 MHz), PCS (1850–1990 MHz), UMTS (1920–2170 MHz), WiBro (2300–2390 MHz), Bluetooth (2.42–2.48 GHz), S‐DMB (2.630–2.655 GHz), and WLAN (5.1–5.37, 5.75–5.9 GHz) frequency bands. Multiple resonators have been connected in parallel in a compact configuration to realize a miniaturized internal antenna for modern multistandard handsets. The proposed monopole antenna has been designed within a volume of 0.43 cm^3^ (20 mm × 14 mm × 1.5 mm) that makes it suitable for ultra‐thin mobile terminals. Two prototype antennas have been fabricated and characterized for return losses and radiation performances which are quite reasonable at all the targeted frequency bands. © 2009 Wiley Periodicals, Inc.
