A New Wide Angle Scanning Liquid Crystal Leaky Wave Antenna

The necessary components to reduce the wide Angle beam scanning antenna, leaky wave antenna scanning Angle at the same time maximize the cycle, reduce the cost of materials, this paper find a new kind of liquid crystal materials, application on the design of liquid crystal planar periodic leaky wave antenna. The antenna is composed of multilayer medium, by adjusting a series of parameters to improve antenna matching and deflection Angle of the beam, the design parameters of the antenna are also given in this paper, by using HFSS electromagnetic simulation computation, the optimal structure of the antenna is determined finally. The simulation results show that the antenna reached - 90 °, 90 ° deflection of the beam,The gain is higher than 8dB. Finally, wide Angle scanning of beam is realized.
