| 摘 要： | 提出了一种新型的基于环形电桥结构的宽带平面和差网络。首先提出了一种新型的宽带微带/槽线转换结构,然后将该结构引入到传统的环形电桥结构中,优化设计了一种改进型环形电桥,最后采用四个改进的环形电桥构建了双平面和差网络。测试结果表明:在4.05～7.425GHz的频率范围内,八个端口的驻波均小于2,输入端口之间的隔离度均在20dB以上,输出端口之间的隔离度大于30dB,和端口的插入损耗小于0.5dB,差端口的零值深度小于-30dB。该和差网络具有性能优良、结构简单、制作成本低等优点,在宽频带单脉冲雷达天馈系统中得到了成功的应用。

| Abstract: | A novel broadband planar sum-and-difference network based on ring bridge race circuit structures is presented in this paper.A new microstrip-to-slotline transition structure with wideband characteristics is proposed firstly,and then a modified rat race circuit which adopts the transition structure considered here is designed.Four such modified ring bridge circuits are connected to form the two-dimensional broadband planar sum-and-difference network.The measured results have demonstrated that the operating b... |
