Abstract
An electronic device () includes an antenna system () having two antennas (). A first antenna () has a first antenna element () positioned near a first corner () of a planar, rectangular ground plane () and a second antenna element () positioned near a second corner of the ground plane that is diagonally across from the first corner. A second antenna () has a third antenna element () positioned near a third corner () of the ground plane that is adjacent to the first corner and a fourth antenna element () positioned near a fourth corner () of the ground plane that is diagonally across from the third corner. At low-band frequencies, the antenna elements () of the first antenna () are driven out-of-phase relative to each other. Similarly, at low-band frequencies, the antenna elements () of the second antenna () are driven out-of-phase relative to each other.
