摘要

本文设计了一种适用于Ku波段波束导向相控阵的可调谐功率分配器。在四元相控阵的功率分配器中加入了基于变容管的希夫曼移相器。所提出的移相器仅通过调节一个控制电压即可产生连续的移相变化。因此，功率分配器能够以12.7 GHz的最大转向角18.8°连续引导其波束。通过改变二极管的电压，可以得到主光束的不同方向。

Tunable Power Divider With Varactors Based Schiffman Phase Shifters for Antenna Arrays Beam Steering

A tunable power divider appropriate for beam steering phased antenna array in the Ku band is designed in this paper. Varactors based Schiffman phase shifters are added to the power divider of four elements phased array. The proposed phase shifter generates a continuous phase shift variation by adjusting only one control voltages. Thus, the power divider can be able to steer continuously its beam with a maximum steering angle of 18.8° at 12.7 GHz. Various directions of the main beam are obtained by changing the diodes voltages.
