Abstract

UN SISTEMA DE ANTENA COMPUESTA PARA UN SISTEMA DE SUPERVISION DE ARTICULOS, EN LA QUE SE SUMINISTRAN UNA GRAN VARIEDAD DE ANTENAS DE FASE BOBINADA DIFERENCIADAS CON CORRIENTES DISTINTAS PARA PROPORCIONAR LA POSICION DESEADA DE LOS PICOS Y PARA ANULARLOS EN LA RESISTENCIA DEL CAMPO CERCANO, Y PARA PRODUCIR RESISTENCIAS DEL CAMPO LEJANO CERCANAS A CERO, SEGUN SE DESEE. EN UNA FORMA PREFERENTE, SE SITUA UNA BOBINA MAS PEQUEÑA CERCA DEL SUELO Y OTRA MAYOR POR ENCIMA DE LA ANTERIOR, CON LA PEQUEÑA PROVISTA DE CORRIENTE DE MAYOR INTENSIDAD CORRESPONDIENTE PARA PROPORCIONAR UNA RESISTENCIA DE CAMPO CERCANO REALZADA CERCA DEL SUELO, MIENTRAS QUE SE MANTIENE LA CANCELACION DEL CAMPO LEJANO.
