Abstract:
A multi band antenna system () 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 (), a second conductor (), a common feed conductor () coupled to the first conductor and the second conductor, and a ground conductor () 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.
