摘　　要：双环天线在3G基站中的应用是一种新的探索与尝试。本文对双环天线在3G基站中应用的方向图特性、阻抗匹配以及宽频带性能等进行了仿真研究与分析。为了更好地抑制第一副瓣电平,提出了对双环天线进行改进的方案。通过仿真检验,改进后的双环天线能抑制第一副瓣电平约1.4dB。应用改进的双环天线设计了一种基站天线,测试的结果均达到了指标要求,证实了双环天线在3G中的适用性。It is a new attempt and exploration to apply the dual-loop antenna to the 3G base station. In this paper, the characteristic of dual-loop antenna is studied, in which patterns, impedance and broadband are included. To control the first side-lobe level, a modificated version for the Dual-Loop Antenna is studied. The simulation result validates that the modification can suppress side-lobe by 1.4dB. A base station antenna is designed based on the improved Dual-Loop Antenna, the test results are good and the applicability is demonstrated in the 3G base station.
