Abstract

UNA ANTENA MULTIBANDA (10) QUE SE ADAPTA PARA RECIBIR SEÑALES EN LAS BANDAS AM/FM Y PARA RECIBIR Y TRASMITIR SEÑALES EN UNA FRECUENCIA MAS ALTA, COMO LAS QUE UTILIZAN LOS TELEFONOS CELULARES. SE FORMA LA ANTENA PARA AM/FM MEDIANTE UN TUBULAR (14, 16) Y LA ANTENA PARA LA BANDA DE FRECUENCIA MAS ALTA SE FORMA UTILIZANDO UN DIPOLO COAXIAL ALIMENTADO CENTRALMENTE (12), MONTADO EN LA PARTE SUPERIOR Y COAXIALMENTE DE LA ANTENA DE AM/FM. EL DIPOLO (44, 46) SE ALIMENTA POR UN TUBULAR (48) AÑADIDO AL CABLE COAXIAL (26) QUE SE EXTIENDE A LO LARGO DE LA ANTENA AM/FM (14, 16). UNA REACTANCIA (50) SE COLOCA CERCA DEL TUBULAR COAXIAL Y ESPACIADA A UNA DETERMINADA DISTANCIA DE LA ANTENA DIPOLO PARA REDUCIR EL ACOPLAMIENTO ENTRE LA ANTENA AM/FM (14, 16) Y LA ANTENA DE ALTA FRECUENCIA (12). LA REACTANCIA (50) FUNCIONA PARA POSICIONAR LA IMPEDANCIA DE ENTRADA DE LA ANTENA DE ALTA FRECUENCIA EN LA BASE DE LA IMPEDANCIA, DE MANERA QUE UN TRANSFORMADOR SE PUEDA UTILIZAR EN LA BASE DE LA REACTANCIA PARA SU CONEXION CON EL CABLE COAXIAL. AL DISPONER LA ANTENA DE ESTA MANERA, EN LA BASE DE LA REACTANCIA, SE PRESERVAN LAS MEJORES CARACTERISTICAS POSIBLE DEL VSWR DE LA ANTENA Y LA PAUTA DE RADIACION DEL LOBULO PRINCIPAL DE LA ANTENA SE EXTIENDE HORIZONTALMENTE A LO LARGO DEL EJE HORIZONTAL.
