Abstract
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.
