Abstract

An internal antenna for GSM (880∼920MHz), DCS (1710∼1880MHz), and US-PCS (1850∼1990MHz) mobile handset is proposed. The antenna is designed to have a multi-band operation and includes feed line, patch and matching stub. It has a single radiating element and operates in multi-band by a matching circuit. The measured peak gain is 0.11dBi, 1.65dBi and 0.13dBi for GSM, DCS, and US-PCS, respectively.
