| 摘 要： | 提出了一种新颖的波导-微带线的背靠背过渡结构,利用Quasi-Yagi天线结构在波导E面与波导形成电场耦合,通过采用高介电常数基片和增加Yagi天线引向器阶数的方法,改善天线与波导的电场耦合效果,以达到在通频带内平稳过渡,较传统的波导微带过渡结构有着更宽的带宽(将近68%)。通过电磁仿真软件CST在整个X波段对其进行了全波分析,得到了较好的S21(S21<0.7 dB)。对这种过渡结构进行了容差分析,在10%的误差范围内S21仍能保持较好的一致性和相对低的插入损耗,能满足加工要求。

| Abstract: | A novel waveguide-microstrip back to back transition structure by utilizing Quasi-yagi Antenna is introducted in this paper.By adopting high dielectric substrate and adding numbers of the Yagi antenna director,electromagnetic coupling effect between antenna and waveguide is improved to make a smoother transition in passband.Compared with traditional waveguide-microstrip structure,it has a advantagment of wider bandwidth (nearly 68%).Through electromagnetic software CST,a full-wave analysis in the whole X-ba... |
