Abstract

ANTENA DIPOLO PARA TRANSMISORES-RECEPTORES PORTATILES.COMPRENDE UNA PUERTA DE ALIMENTACION, CON DOS NODOS DE ENTRADA Y DOS RADIADORES. UNO DE ESTOS EXHIBE UNA LONGITUD ELECTRICA MENOR QUE LA DEL OTRO, Y UN ELEMENTO REACTIVO ACOPLA EL EXTREMO DE AQUEL RADIADOR MAS PROXIMO A LA PUERTA DE ALIMENTACION CON UNO DE LOS DOS NODOS DE ENTRADA. EL ELEMENTO TIENE UNA REACTANCIA ELECTRICA INSUFICIENTE PARA AUMENTAR LA LONGITUD ELECTRICA DEL SEGUNDO RADIADOR A UN CUARTO DE UNA LONGITUD DE ONDA PREDETERMINADA.
