Abstract

A novel 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 performance is simulated with Ansoft Ensemble 8.0 software. The bandwidth is 83 MHz for GSM band (9.22 %) and 730 MHz for DCS band (40.56 %). The results of simulation and experiment are compared and found to be in good agreement. The antenna has the merits of low profile, light weight and low cost. It has potential application in cellular mobile communications.

一种新型GSM/DCS双频蜂窝通信天线

提出了一种新型的双频单层贴片天线;它覆盖GSM的890-960 MHz和DCS的1710-1880 MHz频段，VSWR/spl /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。采用Ansoft Ensemble 8.0软件对其性能进行了仿真。GSM频段的带宽为83 MHz (9.22%)， DCS频段的带宽为730 MHz(40.56%)。将仿真结果与实验结果进行了比较，两者吻合较好。该天线具有外形小、重量轻、成本低等优点。在蜂窝移动通信中具有潜在的应用前景。
