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).
