ABSTRACT:
A grounding method for use in high frequency electrical circuitry has a conductive elastomeric member with a low resistivity per square. The conductive elastomeric member is placed in contact with the ground plane of a circuit board and a conductive housing within which the circuit board is situated. The conductive elastomeric member is deformed to flow into discontinuities of a ground path between the ground plane and the conductive housing so that the discontinuities do not act as antennae to radiate energy in response to high frequency signals.
