摘要
本文利用三维高频仿真软件HFSS设计并分析了中心频率为15GHz的波导-微带过渡结构。这种结构的输入输出是直通方向的,与以往的波导-微带过渡结构相比,这种结构体积小、气密性好、更利于小型化。根据测试结果,设计的过渡结构在13GHz—17GHz频率范围内有良好的性能,插入损耗小于0.5dB,端口驻波系数小于1.35。
A ku-band waveguide to microstrip transition structure with 15GHz of central frequency is designed and analyzed by using 3-dimensional high frequency simulation software （HFSS）. In this transition structure, the waveguide and microstrip line are connected in a straight line. Comparing with the former waveguide to microstrip transit structure, this structure is featured with small size and good airtightness, and is benefit to miniaturization. On basis of tested results, the designed transit structure has perfect performance within 13GHz-17GHz of frequency range, its insertion loss is less than 0. 5dB, and the port standing wave ratio is less than 1.35.
