Abstract

In this paper, a dielectric extended hemispherical lens antenna is presented. The antenna has been designed to produce highly directive beams at low THz frequencies. The feeding mechanism is a standard WR-3 rectangular waveguide
fitted at the bottom of lens. The antenna is suitable for newly developed waveguide-based automotive radar and communications systems. The initial geometry has been based on ray optics and has then been optimized using full wave simulations (CST Microwave StudioTM). Various dielectric materials have been considered and rexolite (εr=2.53) has been chosen for the particular design. The antenna’s central frequency is 286 GHz with a maximum gain of 38.4 dBi and a 3dB
bandwidth of around 40GHz.
