摘要
为了解决传统三等分功分器输出支路跨接隔离电阻实现困难的问题,基于Wilkinson功率分配器设计理论,通过引入二分之一波长微带传输线,提出了一种新型微带三等分功率分配器的设计方法。基于此方法,设计了一款应用于海事卫星通信频段的对称结构三等分功分器。实测结果表明该功分器在整个设计频带内各端口匹配好,各输出支路等分度好、隔离度高。该功分器已成功应用于天线阵馈电网络的设计。
In order to solve the problem that it is difficult to realize installation isolation resistor across each outputs, the design and development of a new type of three-way microstrip equal power divider are presented in this paper. It is realized by introducing a half-wavelength microstrip transmission line based on Wilkinson power divider design theory. A symmetry three-way equal power divider is designed for maritime satellite communication application. The measured results show that it has a good matching at each port and a high isolation between each outputs. It has been successfully applied in the design of antenna array feeding network.
