【摘要】 本文首先在蘑菇型EBG结构的基础上,采用半波长微带谐振器,结合了微带线的优点,构造了V波段的微带脊间隙波导模型及微带过渡。然后将物理交叉耦合和模式交叉耦合两种方式相结合,设计了一款五阶V波段带通滤波器,该滤波器通带两端各有一个传输零点,提高了滤波器的选择性。实物测试结果及仿真结果均表明:本文设计的基于脊间隙波导的V波段交叉耦合带通滤波器性能良好,在62-64GHz频段内回波损耗S11小于-10dB,插入损耗约-2.5d B,具有小型化、低插损、高抑制等特点,有很大的工程实用价值。更多还原

【Abstract】 Based on the mushroom-type EBG structure, this paper first uses a half-wavelength microstrip resonator and combines the advantages of a microstrip line to construct a V-band microstrip ridge gap waveguide model and microstrip transition. Then a combination of physical cross-coupling and mode cross-coupling is used to design a fifth-order V-band band-pass filter. The filter has a transmission zero at each end of the pass band, which improves the selectivity of the filter. The physical test results and simulation results show that the V-band cross-coupled band-pass filter based on the ridge gap waveguide designed in this paper performs well. The return loss S11 is less than-10 dB and the insertion loss is about-2.5 dB in the 62-64 GHz band. Features such as miniaturization, low insertion loss, and high suppression have great engineering value.更多还原
