Abstract
Radio frequency antennas sharing a ground plane are largely decoupled using one or more lumped capacitive elements set into holes within the ground plane. The holes, which are precisely placed, can extend to a side of the ground plane. A stub extends from a fringe of the hole either straight or bending in an L shape, and a capacitor connects between an end of the stub and another side of the hole. Capacitive elements can also be supported on raised solder pads above a ground plane or off to one side of the ground plane. Methods for manufacturing the decoupling apparatus are described.
