摘要

设计了一种工作频率为3.9 ~ 15.3 GHz的高性能宽带四脊喇叭馈电系统。为了在溢出效率和孔径效率之间找到平衡，保证高灵敏度，利用粒子群优化算法对样条脊和角进行了优化。通过计算和优化，QRFH在工作频段内的平均灵敏度大于4.6 m2/K，平均孔径效率大于65%，两个端口的回波损耗大于14 dB。

Wideband Quad-Ridged Flared Horn Feed Design and Optimization Based on PSO Algorithm

A high performance wideband quad-ridged flared horn (QRFH) feed has been designed which operates from 3.9 –15.3 GHz. In order to find the balance between spillover efficiency and aperture efficiency to ensure the high sensitivity, spline-profiled ridges and horn have been optimized with the help of particle swarm optimization (PSO) algorithm. Through computation and optimization, the average sensitivity of the QRFH is greater than 4.6 m2/K, the average aperture efficiency is more than 65% and the return losses of two port are greater than 14 dB within the working frequency band.
