Abstract

SE DESCRIBE UNA ANTENA EXTENSIBLE ACOPLADA INDUCTIVA PARA TELEFONOS SIN CABLE Y PARA TELEFONOS CELULARES PORTATILES. LA ANTENA ES OPERADA, EN SU ESTADO EXTENDIDO, COMO EL EQUIVALENTE DE UNA ANTENA DIPOLO DE MEDIA ONDA DEBIDO A LA CAPACIDAD DE ACOPLAMIENTO INDUCTIVO ENTRE EL ELEMENTO DE ANTENA HELICOIDAL DE CUARTO DE ONDA Y EL ELEMENTO DE ANTENA DE LATIGO DE CUARTO DE ONDA Y COMPENSA, EN SU ESTADO CONTRAIDO, EL COMPONENTE DE CAPACIDAD DEFICIENTE DEL ELEMENTO DE ANTENA HELICOIDAL DEBIDO AL ACOPLAMIENTO INDUCTIVO DE CAPACIDAD ENTRE EL MANGUITO DE METAL Y EL ELEMENTO DE ANTENA HELICOIDAL. LA ANTENA TAMBIEN MEJORA LA EFICACIA DEL ELEMENTO DE ANTENA DE LATIGO ASI COMO LA EFICACIA DEL ELEMENTO DE ANTENA HELICOIDAL MEDIANTE EL ACOPLAMIENTO DEL MANGUITO DE METAL A UN TUBO CON LA CONDICION DE QUE EL ELEMENTO DE ANTENA DE LATIGO ESTE COMPLETAMENTE INSERTADO EN EL TUBO.
