一种基于模式匹配法的窄带Iris波导滤波器设计
Design of a Narrow-Band Iris Waveguide Filter Based on Mode-Matching Method
摘要
Abstract
A design method of narrow-band Iris waveguide filter based on Mode-matching is proposed. This design cycle of the filter is shortened a third by the help of Matlab optimization. The relative bandwidth of narrow-band filter is less than 3%. This filter overcomes the problem that high frequency out of band suppression is poor in the millimeter-wave band. The test results show that the insertion loss of the filter is less than 0.8 dB,voltage standing-wave ratio(VSWR)is better than 1.2,center frequency is 34.86 GHz,the out-of-band rejection is 52 dB at 36.5 GHz and it has been successfully used in a millimeter wave radar communication system.关键词
