Design of cylindrical conformal liquid crystal phased array antenna

Abstract

Because the liquid crystal material has fluidity and electrical control characteristics, it is suitable for conformal phased array design, this paper designed a cylindrical conformal phased array antenna based on liquid crystal material. The designed conformal phased array antenna has a center frequency of 15GHz, a 5×5 uniform array, and a cylindrical radius of 80mm, which can achieve gradient gain scanning (14.17dBi-21.4dBi), and the scanning range is ±30°. The designed antenna array has certain practical prospects.
