A multi-band antenna having a tuned antenna element is disclosed. The multi-band antenna may simultaneously transmit a first radio frequency (RF) and a second RF signal. The antenna may include a driven antenna element to radiate the first RF signal and a parasitic element to radiate the second RF signal. The parasitic element may be coupled to a ground plane through a tuning circuit. The tuning circuit may modify a resonant wavelength of the parasitic element according to the second RF signal.
