RGW based Leaky Wave Antenna for Terahertz Application

Sina Rezaee, Mohammad Memarian

Open publisher page 4 citations

Abstract

In this paper, a continuous beam scanning leaky-wave antenna (LWA) is proposed for terahertz (THz) applications. The proposed LWA uses Ridge Gap Waveguide (RGW) technology which is alternated with silicon rods. As its primary advantage, this LWA has gapless dispersion with linear behavior, which is often suffered by conventional LWAs. Also, the equivalent circuit of LWA is provided that verifies the proper closure of the bandgap. As operating frequencies increase from 430 to 550 GHz, the proposed LWA achieves a continuous beam steering about 85°, scanning from forward to broadside and then the backward direction with stable high gains and no degradation at broadside. The proposed LWA provides a simple solution for THz applications.
