摘　　要：通过大量的仿真和数据分析对双频天线进行了研究。该双频天线采用L型探针馈电,低频采用单贴片,高频采用双贴片,高频位于低频的正上方。低频段为824～960MHz,高频段为1710～2170MHz,高低频增益均在8.5dB以上。适合于作移动通信基站天线,特别适合于2G到3G过渡时期的移动通信系统。We have investigated dual-band antenna by a great number of simulation and date analysis. The patch feed by L-probe has been adopted in this dual-band antenna, single patch in low frequent （824 - 960 MHz） and dual-patch in high frequency （1 710 - 2 170 MHz） above the low frequency. The gain is more than 8.5 dB for the two bands. This antenna is very suitable for mobile communication base station antenna, especially the transition stage from 2G to 3G.
