Abstract

A novel GSM/DCS dual-band single layer patch antenna is presented, it covers the bands of (890-960) MHz for GSM and (1710-1880) MHz for DCS with VSWR /spl les/2. This antenna consists of a ground plane, air layer, and a metal patch layer printed on a thin substrate with lower permittivity. The initial sizes of the antenna are determined by using of transmission line model, then, the performances of antenna are simulated and optimized with Ansoft Ensemble 8.0 software. The bandwidth of 83 MHz for GSM band (9.22 %) and 730 MHz for DCS band (40.56 %) has been obtained. The results of simulation and experiment are compared.
