| 摘 要： | 设计了一种三频段L型单极子平面天线,通过3个L型单极子天线的组合,使其中一个单极子天线工作于3.5 GHz频段,较长一个单极子工作于2.4 GHz频段,较短一个单极子工作于5.8 GHz频段,该天线与其他三频段平面天线相比,结构更为简单。为数值分析和优化,在HFSS建立了该天线的电磁仿真模型,仿真结果表明,该三频段天线在其3个工作频段内的回波损耗都＜-10 dB,实现了2.4 GHz,3.5 GHz和5.8 GHz 三频段同时工作。该天线可在WLAN和WiMAX通信系统中得到良好的应用。

| Abstract: | This paper designs a triple-band L monopole planar antenna composed of three L monopole antennas,one of which is for the 3.5 GHz band,the longer one for the 2.4 GHz band and the shorter one for the 5 GHz band.This antenna is simpler in structure than other planar antennas designed for realizing triple-band characteristics.An electromagnetic (EM) model of the designed antenna is developed in HFSS for numerical analysis and optimization.The simulation results show that the antenna with Return Loss (S11) less than -10 dB at three resonance points that are 2.4 GHz,3.5 GHz and 5.8 GHz,respectively.The designed triple-band antenna is suitable for WLAN and WiMAX applications of communication system. |
