Abstract

In this paper, we devise a phased array antenna with liquid crystal material, employing a 10×10 uniform rectangular array. The phase of the phased array antenna is controlled by loading bias voltage on the liquid crystal layer, and the FoM (figure-of-merit) of the phase shifter can attain 70.6°/dB. The phased array antenna works at 16 GHz and employs a microstrip circular patch as the radiation unit. The proposed phased array can achieve a gain of 23.1 dBi, and its beam scanning range reaches ±45° in simulation experiment. The preliminary measurement results demonstrate that the performance of the proposed antenna is basically consistent with simulation results.
