摘要 设计了一种改进结构的嵌入盘形天线,该天线具有低剖面、宽频带及全向的特点,并要求工作时最大辐射方向是45°。通过对嵌入盘形天线进行刻缝和加导电柱等结构上的改进后,可以在降低天线尺寸的前提下实现天线的低剖面、宽频带以及较大的水平增益。天线中心频率为3.0GHz,剖面高度远小于中心频率波长。在2.5～4.0GHz频带内,驻波比小于2,并且,水平方向增益可达-2dB。用AnsoftHFSS软件进行仿真计算,并对实际天线进行了测试。测试结果与仿真结果有很好的一致性,满足设计要求。 A modified flush-disc antenna with characteristic of low profile,wideband and omni direction is proposed.The largest radiation of the antenna is at 45 degree.By adding slots and conducting pins,the antenna can achieve broad bandwidth and high horizontal gain with a low profile.The profile height of the antenna is far less than the operation wavelength in the center frequency 3.0GHz.The antenna covers a bandwidth of 2.5～4.0GHz.Its VSWR is smaller than 2 and the gain in the horizontal plane is up to-2dB.The antenna is simulated using software Ansoft HFSS and a practical measurement of the designed antenna is tested.The result of measurement is in good agreement with the result of simulation.The design requirements are satisfied.
