Phased Array of Dielectric Cuboid Antenna at 300 GHz Band

Abstract

We show the basic characteristics of a phased array of dielectric cuboid antenna operating at 300 GHz band based on a simulation. The antenna gain, radiation pattern, and beam steering characteristics are examined. In the 4-element linear array configuration with a 1.0 mm$\times 5.5$ mm aperture size, the maximum antenna gain of 20.3 dBi was achieved though it decreases at the wider steering angle. The beam steering range of $\pm 17.6^{\mathrm{o}}$ was achieved.
