Abstract
A liquid crystal (LC)-based double dipole terahertz phase shifter is proposed. The block model is utilized in simulations to analysis the influence of inhomogeneity of the LC substrate. The sensitive parameters of the double dipole are simulated and analyzed. An array consisting of 30 × 30 patch elements is designed and fabricated. Experimental results exhibit that the phase shift is over 360° in the range of 355.8–358.8 GHz at 1 kHz, at an applied AC bias in the 0–50 V range. The phase change at different frequencies of AC bias voltage is also investigated, and the effect of the frequency of AC bias voltage is expressed by the coefficient of the amplitude of the bias voltage.
