An antenna backplane including a printed circuit board (PCB) having a first differential pair with a first conductor and a second conductor and a second differential pair with a third conductor and a fourth conductor. The first conductor is positioned a first distance from the second differential pair and the second conductor is positioned a second distance from the second differential pair of conductors, 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. A phase-shifting series resonant circuit is coupled between the first conductor and the fourth conductor that provides approximately an odd-integer multiple of a 180 degree phase shift at a predetermined frequency.
