摘要

提出了一种基于液晶材料的平面反射天线。首先，构造了一种新型环形偶极子小型化液晶天线反射单元。该反射器单元在35GHz时可实现400°相移，损耗小于4.5dB。然后，利用该单元设计了11×11液晶反射天线，阵列天线的主波束扫描角范围达到±20°。当阵列天线偏转角度为20°时，天线增益为14.9dBi，第一副瓣电平为−9.1dB。

Research on electronically controlled planar reflectarray antenna based on liquid crystal material

A planar reflectarray antenna based on liquid crystal materials is presented in this paper. First, a new type of loop dipole miniaturized liquid crystal antenna reflection unit is constructed. The reflector unit can achieve 400° phase shift at 35GHz, and the loss is less than 4.5dB. Then, an 11×11 liquid crystal reflectarray antenna is designed using this unit, and the main beam scanning angle range of the array antenna reached ±20°. When the deflection angle of the array antenna is 20°, the gain of the antenna is 14.9dBi, and the first sidelobe level is −9.1dB.
