2~18GHz宽带波束网络的设计

The Design of 2~18 GHz Broadband Beam-Forming Network

给出了一种2~18GHz宽带波束网络的设计方法,其核心电路由Wilkinson功分器和平面巴伦构成,平面巴伦由开路和短路耦合传输线实现,最后基于ADS完成了2〜18GHz宽带波束网络的仿真设计。仿真结果证明,该波束网络能够对来自四个不同天线的波束进行和差操作。

The design method of a broadband 2〜18GHz beam-forming network is described.Wilkinson power divider and planar balun are core circuits of the broadband beam-forming network,open and short coupling transmission lines are composed of the planar balun.The design of the 2〜18GHz beam-forming network is accomplished using ADS finally.Simulation results prove it can sum and difference beams coming from four different antennas.
