波导带通滤波器与微带转换装置的设计
Design of transition device between waveguide bandpass filter and microstrip
摘要
Abstract
A K-band E-plane bandpass waveguide filter with seven-order inductance and a waveguide-tcrmicrostrip transition are designed using HFSS, a three-dimensional simulation software. The bandpass waveguide filter has 19 GHz center frequency, 3 GHz bandwidth, 0. 1 dB inband transmission loss, and less than-20 dB reflection coefficient. And the port reflection coefficient contributed by the waveguide-to-microstrip transition is less than-20 dB from 16 GHz to 20. 8 GHz bandwidth, and inband transmission loss is less than 0. 1 dB. Then the combination of the filter and the transition covers bandwidth from 17. 5 GHz to 20. 5 GHz in which in'uand transmission loss is less than 0. 3 dB, port reflection coefficient is less than-15 dB, out-of-band rejection is less than-30 dB, which meets the demands of the real system.关键词
