摘要
喇叭天线由于其特有的性能,在无线电领域应用广泛。本文首先介绍了喇叭天线的构成,对其口径场、辐射方向性进行理论分析,然后分析了脊波导参数。最后根据理论分析,初步设计了一个频率在1~8 GHz范围内驻波比小于2的双脊喇叭天线,使用CTS仿真软件对关键参数扫描优化,并观察了电场分布情况,进一步验证了理论分析的合理性。从仿真结果可以看出,本设计是合理可行的,具有实际应用价值。
As the characteristic of horn antenna,it is widely used in the radio field.This article firstly introduced the structure of horn antenna,and gave a theoretical analysis in aperture-field distribution,radiation pattern.To further enhance the working frequency bandwith,ridged waveguide model in induced.Based on the theoretical analysis,this article designed an original DRHA which frequency range is from 1 GHz to 8 GHz.By using the simulation software,some critical parameters was swept,and an optima DRHA was achieved,that further verified the rationality of the theoretical analysis.Form the simulation results,it can be concluded that the design is feasible and has some valuable experience for LPDA design in EMC testing.
