摘要

提出了一种新型GSM/DCS双频单层贴片天线，覆盖GSM (890 ~ 960) MHz频段和DCS (1710 ~ 1880) MHz频段，VSWR /spl les/2。该天线由接地面、空气层和印刷在低介电常数薄衬底上的金属贴片层组成。利用传输线模型确定了天线的初始尺寸，利用Ansoft Ensemble 8.0软件对天线的性能进行了仿真和优化。GSM频段的带宽为83 MHz (9.22%)， DCS频段的带宽为730 MHz(40.56%)。仿真结果与实验结果进行了比较。

Transmission line model analysis: a novel GSM/DCS dual-band single layer patch antenna

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.
