A New Leaky-Wave Directional Coupler in Hybrid Dielectric-Waveguide Printed-Circuit Technology

Abstract

-This paper presents the design of a novel leakywave coupler, based on hybrid dielectric-waveguide printedcircuit technology. The working mechanism of the proposed structure is explained, and the design procedure is illustrated in order to obtain the geometrical dimensions for a coupler working at 5.5GHz. The design is performed using commercial electromagnetic analysis software. This novel directional coupler presents interesting advantages when compared to previous wave couplers.
