| 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。 |

| Abstract: |
| In order to solve the problem that it is difficult to realize installation isola
tion resistor across each outputs, the design and development of a new type o
f three-way microstrip equal power divider are presented in this paper. It is r
ealized by introducing a half-wavelength microstrip transmission line based on W
ilkinson power divider design theory. A symmetry three-way equal power divider i
s 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 arra
y feeding network. |
