Tecnologías para guiado de ondas en bandas milimétricas utilizando estructuras periódicas: diseño y simulación de una guía de onda en la banda de milimétricas utilizando la tecnología ridge gap waveguide (RGW).

Abstract

Microwave engineering has advanced significantly in recent years, thanks to a series of re- search focused on waveguiding, the development of new transmission technologies, as well as the design of circuits that allow for greater system efficiency. While conventional wavegui- des have advantages such as handling high powers and low losses, it is no less true that the frequency requirement limits its use in new applications. The implementation of planar trans- mission lines could not satisfy the requirement of working in millimeter bands, so “Ridge Gap Waveguides” are presented as one of the solutions to this problem, by implementing periodic structures that generate the absence of electrical contact between the metallic surfaces that make up the structure. This document collects information on microwave and radiofrequency transmission media, and evaluates the Gap Waveguide technology, particularly the Ridge guide, as a useful tool for problem-solving in this area.
