摘　　要：针对6G无线通信系统对毫米波带通滤波器的需求,提出一种工作频段为W波段的毫米波双频带通滤波器。基于对多模谐振腔的研究,利用谐振腔内的TE301模式和TE102模式设计一种超宽带谐振腔,并基于TE302模式和TE103模式设计一种具有传输零点的多模谐振腔,通过将这两种谐振腔进行级联和优化,设计出一款工作于W波段的双频带通滤波器。两个工作频段分别为83.26~91.54 GHz和96.58~105 GHz,3 dB相对分数带宽分别为9.5%和8.4%。3个传输零点的位置分别在81.12、93.3、109.31 GHz。所设计结构采用CNC工艺进行制备,经测试,测试结果与仿真结果具有良好的一致性。两个工作频段的3 dB相对分数带宽误差分别为0.3%和1.5%。因此,所提出的W波段双频带通滤波器的设计方式可以为高频毫米波的设计带来一定的参考价值。Aiming at the demand of millimeter-wave band-pass filter for 6G wireless communication system,a millimeter-wave dual-band band-pass filter with W-band working frequency is proposed.Based on the study of multi-mode resonators,an ultra-wideband resonator is designed by using TE301 mode and TE102 mode in the resonator,and a multi-mode resonator with transmission zeros is designed based on TE302 mode and TE103 mode.By cascading and optimizing these two resonators,a dual-band bandpass filter working in the W-band is designed.The two operating bands are 83.26-91.54 GHz and 96.58-105 GHz,respectively,and the 3 dB fractional bandwidth is 9.5%and 8.4%,respectively.The locations of the three transmission zeros are at 81.12 GHz,93.3 GHz and 109.31 GHz.The designed structure is prepared by CNC process.After testing,the test results are in good agreement with the simulation results.The 3 dB fractional bandwidth errors of the two operating bands are 0.3%and 1.5%,respectively.Therefore,the proposed design method of W-band dual-band bandpass filter can bring some reference value for the design of high frequency millimeter wave filter.
