Abstract

This paper presents a terahertz high-gain antenna which has a certain beam scanning capability and the antenna also has an offset Cassegrain reflector structure. Beam scanning method is analyzed by the theory of quasi-optics. Moreover, we elaborate critical analysis algorithm of the antenna. Simulation results show that, in the initial position, the gain of the antenna is 44.98dB, the half-power beam width is 1 degree and the side lobe level is −29.35dB. Beam scanning angle in the horizontal and vertical direction is within ±10° respectively, the gain and beam width vary within a reasonable range and the side lobe level is always lower than −20dB. In general, the antenna can be used for scanning terahertz imaging system.
