摘要
该文设计了一种中心频率为2.4GHz的半波对称振子天线,其工作频率范围为2.3GHz^2.55GHz。利用电磁仿真软件Ansoft HFSS对此天线进行了仿真设计并进行了实验分析。通过设计"巴伦"解决了天线的馈电和阻抗变换问题,并对其回波损耗、驻波比、阻抗匹配以及远场增益的仿真结果进行了分析。结果表明,计算结果与仿真结果吻合良好。该天线基本满足设计要求,可用于移动通信基站天线。
A half-wavelength dipole antenna whose center frequency is 2.4GHz is presented in this paper and its operating frequency range is between 2.3GHz and 2.55GHz.Antennas are simulated and designed by the electromagnetic software Ansoft HFSS.The problems of antenna feed and impedance transformation were resolved by the design of Balun,and the return loss,standing-wave ratio,impedance matching and far-field gain of this antenna were analyzed as well.It comes to the conclusion that the calculation results and experimental results have a quite good agreement.The concerning antennas essentially accord with design requirements,which can be used for mobile communication base station.
