Abstract
A metal gasket for preventing leakage of radio frequency signals when mounting shielded radio electronics includes gasket body having a first surface and an opposite second surface and a plurality of spring arms. Each spring arm includes a free proximal portion and a free distal portion and a connection connecting the spring arm to the body portion. Each spring arm is configured so that the distal portion contacts a component proximate the first surface of the body portion and the proximate portion of each spring arm contacts a second component proximate the second surface of the body. Preferably, the distance between adjacent contacts on a component is less than or approximately equal to a predetermined ratio of a shielded radio wavelength.

A gasket comprising:
- a body having a first surface and a second surface, the second surface opposite the first surface;
- a plurality of spring arms, each spring arm having a free proximal portion, a free distal portion, and a connecting each spring arm to the body;
- the free distal portion of each spring arm is adaptable for contacting a first component adjacent to the first surface of the body and the free proximal portion of each spring arm is adapatable for contacting a second component adjacent to the second surface of the body;
- and
- wherein the distal portion is longer than the proximal portion.
