【摘要】 本文设计了一种基于基片集成波导(SIW)的直通式W波段矩形波导-微带线的过渡结构,在80-100GHz范围内回波损耗优于25dB,插入损耗小于0.6dB。并通过调整部分结构将其应用于92GHz-96GHz的超薄腔体滤波器中,该设计实现了W波段腔体滤波器与射频电路的平面集成化。最终对该结构进行了仿真验证和加工测试。更多还原

【Abstract】 This paper designs a straight-through rectangular waveguide-microstrip transition structure based on Substrate Integrated Waveguide for the W-band. The structure demonstrates excellent performance with a return loss better than 25dB and an insertion loss less than 0.6dB in the frequency range of 80-100GHz. By adjusting certain structure, it is successfully applied to an ultra-thin cavity filter operating at 92GHz-96GHz, achieving the planar integration of the W-band cavity filter and radio circuit. Finally, the structure is verified through simulation and fabricated for testing.更多还原
