一种宽带紧凑型基片集成径向波导功分器设计

分别设计了一分四和一分八的宽带紧凑型基片集成径向波导（SIRW ）功分器，通过馈电探针的阶梯化方式，使常规一分四和一分八SIRW功分器在回波损耗小于-15 dB条件下的相对工作带宽由原先的6％和15％分别提高至58％和61％，仿真得到的带内插耗分别在-6．25 dB和-9．25 dB以内。为了验证仿真数据的准确性，对一分四功分器进行了测试，测试结果性能良好，满足工程使用要求。

Design of A Wideband Compact Radial Waveguide Power Divider Based on Integrated Substrate Waveguide Technology

This paper designs the four-way and eight-way broadband compact substrate integrated radial waveguide (SIRW) power dividers respectively ,by means of stepped feed probe ,makes the relative operating bandwidth of general four-way and eight-way SIRW power dividers increase from 6% and 15% to 58% and 61% respectively w hen the return loss is less than -15 dB ,and the simu-lated intra-band insertion losses are better than -6 .25 dB and -9 .25 dB respectively .To testify the veracity of simulated data ,a test for four-way SIRW power divider is performed .The test re-sults show that the performance is good and can satisfies the engineering application requirement .
