提出了一种新型的开路/短路T形枝节圆环谐振器,通过奇偶模理论对其进行了分析,电磁仿真软件进行了仿真计算,设计了一款工作于P波段(中心频率为0.4 GHz)和L(中心频率为1.2GHz)波段,分数带宽为40%和16.26%的双通带滤波器。该滤波器具有损耗小、体积小、易集成设计等优点,该双通带滤波器及设计方法将来可广泛应用于高集成度的雷达天线阵面网络中。

A new kind of open/ shorted-ended T-shape stub-loaded ring resonator is put forward. Through the theoretical analysis based on odd-even mode theory and the calculation based on electromagnetic simulation software, a dual-band band-pass filter is designed. The center frequency is 0. 4 GHz (P-band) and 1. 2 GHz (L-band), and the fraction bandwidth is 40% and 16.26% respectively. The advantage of this filter is low insertion loss, small volume and easy integration. It is suggested that this dual-band band-pass filter and its design could be widely applied to the high integrated network of the radar antenna array system.
