Transición entre Guía de Onda Estándar y Suspended-Strip Gap-Waveguide para un Text-Fixture en banda Ka

[ES] La tecnología gap-waveguide es un nuevo concepto de línea de transmisión que ha nacido en los últimos años. La idea básica de este tipo de guías es propagar un modo cuasi-TEM a lo largo de un camino determinado en el hueco de aire entre dos superficies metálicas, e impedir todos los demás modos y direcciones de propagación mediante el uso de materiales conductores magnéticos artificiales (AMC). Este trabajo presenta un test-fixture para tecnología suspended-strip gap-waveguide que proporciona un sistema rápido de medida para la fase de prototipado. Para este propósito ha sido desarrollada una transición desde guía de onda rectangular estándar hasta esta nueva tecnología. El kit TRL diseñado y el estudio estadístico de repetibilidad realizado aseguran la fiabilidad del proceso. Varios sencillos circuitos han sido fabricados y medidos.[EN] The gap-waveguide technology is a new concept of transmission line that has emerged in the last few years.

Test-Fixture for Suspended-Strip Gap-Waveguide Technology on Ka-Band

This letter presents a Test-Fixture for a Suspended-Strip Gap-Waveguide technology that provides a fast measurement system for the prototyping stage. For this purpose, a transition from standard rectangular waveguide to this new technology has been developed. A TRL kit and a repeatability study have been made to ensure the reliability of the process, and several straightforward circuits have been manufactured and measuredThis work was supported by the Spanish Ministerio de Ciencia e Innovacionunder projects TEC2010-20841-C04-01 and CSD2008-00068.Gahete Arias, C.; Baquero Escudero, M.; Valero-Nogueira, A.; Vila Jiménez, A.
