Abstract
In this paper, we present the calculation of the impedance and beam pattern of a 6×6 twin-slot antenna array combined with an extended hemispherical silicon lens. The self and mutual impedance of the twin-slot antenna array are simulated by High Frequency Structure Simulator (HFSS), while its radiation pattern is computed by using ray-tracing inside the lens and electric and magnetic field integration on its surface. The distance between two neighboring antennas is set as 282μm (0.61λ0 at 650GHz) to avoid the overlap between the main-lobe beams of the antenna elements. With good imaging quality (i.e., with a Strehl ratio no less than 0.8), the minimum diameter of the lens is found equal to 23mm (~50λ0 at 650GHz).
