  • Publication number: 20070069954
    Abstract: A multi band antenna system (100) and a wireless communication device are disclosed. The multi band antenna system provides coverage over multiple frequency bands. The multi band antenna system comprises a ground surface, a first conductor (102), a second conductor (104), a common feed conductor (106) coupled to the first conductor and the second conductor, and a ground conductor (108) coupled to the first conductor and the second conductor. The first conductor has a first physical length operationally equal to a half wavelength in a first RF band and operationally equal to a full wavelength in a second RF band. The second conductor has a second physical length operationally equal to a half wavelength in a third RF band.
