Abstract
Una primera bobina (110) resonante a una primera frecuencia, y una segunda bobina (120) resonante a una segunda frecuencia, acopladas a una porcion (140) recta conductora de un elemento (130) de antena para formar una estructura para antena de bandas multiples. La primera y segunda bobinas (110) y (120) están, de preferencia, en diferentes longitudes axiales y circunferencias, enrolladas en direcciones opuestas y ubicadas de manera coaxial alrededor del elemento (130) de la antena. Las bobinas adicionales se pueden añadir para acomodar bandas adicionales y las bobinas (150) superiores se pueden usar para lograr una estructura de posiciones multiples.
