1. An antenna backplane comprising:
a printed circuit board (PCB) including a first differential pair having a first conductor and a second conductor and a second differential pair having a third conductor and a fourth conductor, wherein the first conductor is positioned a first distance from the second differential pair, the second conductor is positioned a second distance from the second differential pair, where the first distance is greater than the second distance, the third conductor is positioned the second distance from the first differential pair, and the fourth conductor is positioned a third distance from the first differential pair, where the third distance is greater than the second distance; and
a phase-shifting series resonant circuit coupled between the first conductor and the fourth conductor, said phase-shifting series resonant circuit providing approximately an odd-integer multiple of a 180 degree phase shift at a predetermined frequency.
