Design and Analysis of Terahertz Transmitarray Using 1-bit Liquid Crystal Phase Shifter
This paper presents a 1-bit terahertz liquid crystal (LC) beam-steering antenna. It consists of a feed horn antenna and a flat rectangular transmitarray with 20×20 LC phase shifter unit cells. The unit cell could achieve phase difference within 180°±20° from 329 to 366.4GHz using double-layer of LC when the permittivity of the LC varies between 2.37 (state 0) and 3.29 (state 1). The full wave simulation results indicate that it can realize beam scanning over ±40° at 340GHz. The gain of the transmitarray is more than 21.4dBi.
