摘要
仿真设计并加工测试了一款X波段圆锥喇叭天线。根据工程指标要求,利用HFSS软件对该天线进行建模仿真优化,仿真结果表明在频率段8.0~8.6GHz,带内回波损耗小于-15d B;在8.3GHz时天线最大方向增益达到15d B,E面与H面3d B波束宽度均达到28°,且E面与H面增益方向图对称性良好。最后对天线进行了实物加工与户外环境测试,测试结果为8.3GHz时天线最大方向增益为12.5d B,3d B波束宽度达到26°,测试结果与仿真结果较为吻合,亦满足实际工程需求。
An X-band conical horn antenna is designed and tested.According to the requirements of engineering,the antenna is modeled and simulated by HFSS software.The simulation results show that in the frequency range of 8.0~8.6 GHz,the in-band return loss is less than-15 dB.At 8.3 GHz,the maximum directional gain of the antenna is 15 dB,and the 3 dB beamwidths of both E and H planes are 28°.Moreover,the symmetry of the gain direction pattern of E and H planes is good.Finally,the antenna is processed and tested in outdoor environment.The test results show that when at 8.3 GHz,the maximum directional gain of the antenna is 12.5 dB,and the beam width of 3 dB is 26°.The test results are in good agreement with the simulation results,and also meet the practical engineering requirements.
