摘要
作为单脉冲雷达天馈系统的关键部件,环形电桥在单脉冲天线阵列的设计中得到广泛应用。为了获得带宽更宽、隔离度更好以及功率容量更大的和差网络,文章通过对Gysel功分器拓扑结构的改进,设计了一种新型的宽带环形电桥,该电桥性能优良、功率容量大,其工作频段达到了1.2~1.4GHz。
Hybrid ring, as the key component of the antenna feed system of monopulse radar, has been widely used in the design of monopulse antenna array. In order to obtain the sum-and-difference net- work with wider bandwidth, better isolation and higher power capacity, a new type of broadband hybrid ring is designed based on the improvement of the topological structure of Gysel power divider. The designed hybrid ring has good performance and high power capacity, and its working band is 1.2- 1.4 GHz.
