Abstract

ANTENA FORMADA POR CONDUCTORES DOBLES Y SISTEMA ELECTRONICO DE VIGILANCIA DE ARTICULOS CORRESPONDIENTE, LA CUAL ANTENA INCLUYE UN PRIMER CONDUCTOR PARA SU CONEXION A UNA CARGA ACTIVA Y UN SEGUNDO CONDUCTOR PARA SU CONEXION A UNA CARGA PASIVA, ESTANDO DICHO SEGUNDO CONDUCTOR MUTUAMENTE ACOPLADO, AUNQUE NO CONECTADO CONDUCTIVAMENTE, A DICHO PRIMER CONDUCTOR. EL SISTEMA ELECTRONICO DE VIGILANCIA DE ARTICULOS INCLUYE UN CIRCUITO RESONANTE QUE COMPRENDE UN TRANSMISOR, UNA PRIMERA ANTENA CONECTADA AL MISMO, UN RECEPTOR Y UNA SEGUNDA ANTENA CONECTADA AL MISMO, DE MODO QUE POR LO MENOS UNA DE LAS ANTENAS ESTA FORMADA POR CONDUCTORES DOBLES. LA PRESENTE INVENCION OFRECE MAYOR PRECISION Y FIABILIDAD A LOS SISTEMAS ELECTRONICOS DE VIGILANCIA DE ARTICULOS.
