Abstract
UNA DISPOSICION ELECTRONICA DE VIGILANCIA DE ARTICULOS CON UN MEDIO TRANSMISOR PARA GENERAR UNA SENAL DE MICROONDAS, MEDIOS DE ANTENAS TRANSMISORES PARA IRRADIAR UNA SENAL DE MICROONDAS A UNA ZONA DE VIGILANCIA, UN MARBETE PARA SER FIJADO A UN ARTICULO PROTEGIDO Y OPERABLE PARA RECIBIR UNA SENAL DE MICROONDAS Y REIRRADIAR UNA SENAL DE RETORNO, ANTENAS RECEPTORAS Y UN RECEPTOR PARA DETECTAR LA SENAL DE RETORNO Y ACTIVAR UNA ALARMA CUANDO SE ENCUENTRA UN MARBETE EN LA ZONA DE VIGILANCIA. LA ANTENA COMPRENDE UNA PLURALIDAD DE PLACAS METALICAS ESPACIADAS A LO LARGO DE LA DIRECCION NORMAL DE TRANSITO DE LA ZONA DE VIGILANCIA, Y UN PLANO DE TIERRA METALICO PARALELO A LAS PLACAS METALICAS FORMANDO LAS PLACAS CON EL PLANO DE TIERRA UNA ESTRUCTURA IRRADIADORA O RECEPTORA DE SENAL.AN ELECTRONIC ARTICLE SURVEILLANCE ARRANGEMENT WITH A TRANSMITTER MEANS TO GENERATE A MICROWAVE SIGNAL, TRANSMITTER ANTENNA MEANS TO IRRADIATE A MICROWAVE SIGNAL TO A SURVEILLANCE AREA, TO BE FIXED TO A PROTECTIVE AND OPERABLE ITEM MICROWAVE AND REIRADIATE A RETURN SIGNAL, RECEIVING ANTENNAS AND A RECEIVER TO DETECT THE RETURN SIGNAL AND ACTIVATE AN ALARM WHEN A MARBETE IS FOUND IN THE SURVEILLANCE AREA. THE ANTENNA INCLUDES A PLURALITY OF METAL PLATES SPACED ALONG THE NORMAL DIRECTION OF TRANSIT FROM THE SURVEILLANCE AREA, AND A METAL EARTH PLAN PARALLEL TO THE METAL PLATES FORMING THE EARTH STRUCTURE OF AN IRRADING STRUCTURE .
