摘要
波导馈电网络具有损耗小、功率容量高、幅相分布精度容易控制等优点,广泛应用于波导裂缝阵列天线中。文中介绍了一种波导赋形波束馈电网络的工程设计,对研制过程中的关键技术如波导窄边裂缝耦合器、波导宽边裂缝耦合器及宽带配相波导等进行了详细论述。测试结果表明,馈电网络幅相精度良好,已成功应用于天线系统中。
The waveguide feeding network is featured with low loss,high power capacitance and easy to control its amplitude and phase distribution.It has been applied in waveguide slot array antenna widely.In this paper,the engineering design of a waveguide feeding network with shaped beam is proposed,the important technologies including the design of waveguide wide wall coupler,side wall coupler and wide-band phase compensation are discussed in detail.The experimental results show that the amplitude and phase precision of this feeding network is very good,it has been successfully applied in an antenna system.
