Abstract
A system for reducing unwanted signals comprises a ground plane, a first active component disposed so as to cause signals in the ground plane, a second active component disposed so as to cause signals in the ground plane, wherein the ground plane provides a path for the signals from the first active component to affect the second active component and for the signals from the second active component to affect the first active component, and a filter element configured as a pattern in the ground plane receiving and attenuating the signals from each of the first and second active components.
