Experimental Study of Leaky-wave Antenna Employing Bent Dielectric Waveguide for Millimeter Wave Communication

Abstract

This paper presents experimental results of a leaky-wave antenna employing a bent dielectric waveguide for millimeter wave bands. We utilize the characteristics that the dielectric waveguide radiates electromagnetic waves by inflection, and that the inflected part of the waveguide acts as an antenna. The radiated propagation characteristics from the bent dielectric waveguide are experimentally confirmed. Since the inflected part can be formed anywhere along the length of the waveguide, it is possible to expand communication areas around the waveguide.
