Abstract

UN MIEMBRO DIELECTRICO PUEDE SER DELGADO Y PLANO Y PUEDE TENER SUPERFICIES OPUESTAS PRIMERA Y SEGUNDA. UN MATERIAL ELECTRICO CONDUCTOR SE COLOCA SOBRE LA PRIMERA SUPERFICIE EN UN EXTREMO DE LA PRIMERA SUPERFICIE Y UN MATERIAL ELECTRICO CONDUCTOR SE DISPONE SOBRE LA SEGUNDA SUPERFICIE EN EL EXTREMO OPUESTO DE ESTA. LOS MATERIALES CONDUCTORES MENCIONADOS DEFINEN UNA PRIMERA ANTENA OPERATIVA EN UNA PRIMERA FRECUENCIA. SE PROPORCIONAN MUESCAS EN EL MATERIAL CONDUCTOR DE LA PRIMERA SUPERFICIE. LAS MUESCAS DEFINEN UNA SEGUNDA ANTENA OPERATIVA A UNA SEGUNDA FRECUENCIA MAYOR QUE LA PRIMERA. LAS MUESCAS INCLUYEN PRIMERAS Y SEGUNDAS EXTENSIONES EN UNA DIRECCION TRANSVERSAL A LA DIRECCION RELATIVA DE LOS MATERIALES CONDUCTORES SOBRE LA PRIMERA Y SEGUNDA SUPERFICIES. LA PRIMERA Y SEGUNDA MUESCAS PUEDEN TENER SUSTANCIALMENTE LONGITUDES IGUALES Y PUEDEN ESTAR ALINEADAS ENTRE SI. ADEMAS SE INCLUYEN UNAS MUESCAS TERCERA Y CUARTA QUE SE EXTIENDEN EN DICHA DIRECCION RELATIVA Y COMUNICANDO RESPECTIVAMENTE CON LA PRIMERA Y SEGUNDA MUESCAS. LAS MUESCAS TERCERA Y CUARTA ESTAN EN RELACION ESPACIADA Y PARALELA PARA DEFINIR UNA PORCION CONDUCTORA. LAS LONGITUDES DE LA PRIMERA Y SEGUNDA MUESCAS DEFINEN LA FRECUENCIA DE LAS SEÑALES DE LA SEGUNDA ANTENA Y LAS LONGITUDES DE LAS TERCERA Y CUARTA MUESCAS DEFINEN LA IMPEDANCIA DE LA SEGUNDA ANTENA. SOBRE LA PRIMERA SUPERFICIE DEL MIEMBRO DIELECTRICO SE DISPONE MATERIAL CONDUCTOR ADICIONAL EN COMUNICACION ELECTRICA CON LA PORCION CONDUCTORA. EL MATERIAL CONDUCTOR ADICIONAL SE DISPONE OPUESTO AL MATERIAL CONDUCTOR SOBRE LA SUPERFICIE SEGUNDA Y ESTA PROVISTO CON UNA LONGITUD QUE DEFINE LA IMPEDANCIA DE LA PRIMERA ANTENA.
