摘要
本文设计了一种工作于22-24.2 GHz频带内的K波段宽带波纹喇叭天线,带内回波损耗仿真结果在-20 dB以下,在22、23.1、24.2GHz天线方向图增益仿真结果分别为21.4、21.8、22.2dB,半功率波束宽度分别为16.4、15.6、14.9度,满足设计要求。后续工作将进一步开展喇叭天线的加工及实测,使得该喇叭天线可用于对应波段的接收机强度校准及大气不透明度测量等研究工作中。
In this paper,a K-band broadband corrugated horn antenna operating at 22-24.2 GHz is designed.The simulation results of in band return loss are less than-20 dB.The simulation results of antenna pattern gain at 22,23.1 and 24.2 GHz are 21.4,21.8 and 22.2 dB respectively,and the half power beamwidth are 16.4,15.6 and 14.9 deg,which meet the design requirements.The follow-up work will further carry out the machining and measurement of the horn antenna,so that the horn antenna can be used in the corresponding band of receiver strength calibration and atmospheric opacity measurement.
