Dispositivo Híbrido Plano para la Detección de Hidrógeno usando Microondas

Abstract

Abstract- Este artículo describe el análisis, diseño y construcción de un dispositivo de microcinta capaz de detectar hidrógeno a frecuencias de microondas. La estructura propuesta consiste en una línea de transmisión tipo microstrip híbrida de 10 cm de longitud, en la que parte de la línea de cobre (Cu) se sustituye por una lámina de paladio (Pd) de 10 nm de espesor. Para un dispositivo con una sección de Pd de 2 cm de longitud, expuesto a un 1,6 % de hidrógeno a una presión de 0,4 bar en nitrógeno gaseoso, la detección se realizó midiendo los cambios producidos en una de las resonancias del parámetro de dispersión S21 en la región de frecuencias de alrededor de 3,2 GHz. Los resultados obtenidos demuestran que la detección de hidrógeno es posible mediante la implementación de bajo costo propuesta. Este hallazgo abre la posibilidad de construir sensores de hidrógeno simples mediante la incorporación de películas ultrafinas de Pd en circuitos de microondas planares.
