Abstract In this paper, an electrical array antenna based on liquid crystal (LC) miniaturized phase shifter is designed and simulated, with the capability of beam steering from backfire to endfire. Special chamfered design of meander line is proposed to obtain compact phase shifter based on LC. The antenna integrates phase shifters, power dividers and patch antennas on a substrate to achieve reduced occupied area. The simulated results reveals the beam steering range is from -21° to + 15° at 12.5 GHz.
