Abstract
Disclosed herein includes a wireless device including a first antenna configured to perform wireless communication, a second antenna configured to perform wireless communication, and a parasitic antenna. The first antenna may have a feed connected to a first impedance tuner that is connected to a first ground planes. The second antenna may have a feed connected to a second impedance tuner. The parasitic antenna may be disposed between the first and second antennas, with a feed connected to a third impedance tuner that is connected to a second ground plane. The first, second and third impedance tuners may be adjusted to configure the first, second and parasitic antennas to achieve a same resonant frequency.
