摘　　要：设计一种新型的超宽带脊波导圆极化器。基于常规圆波导极化器工作原理与性能优劣,结合脊波导主要性能,提出将脊波导移相部位与脊片相结合的设计理念。数值分析表明:在2倍频程和2.2倍频程内,驻波比均小于1.02:1;相位特性分别优于90±7°和90±14°。新型极化器电气性能优良,具有体积小、工作频带宽等优势,更有利于传输性能的提升。A novel ultrawideband ridge waveguide circular polarizer is designed. Based on the principle and performance of conventional circular waveguide polarizer, combined with the main performance of ridge waveguide, the design concept of combining ridge waveguide phase and spine is proposed. The numerical analysis show that the VSWR is less than 1.02：1, in both cases of 2 and 2.2 times frequency range, and the phase characteristics are better than 90±7° and 90±14°, respectively. The electrical performance of novel polarizer is excellent, with advantages including small size and wide frequency, showing the conducivity to its improvement of transmission performance.
