Foil laminate for hermetic enclosures

Abstract:

An electronics enclosure is configured to provide protection against a wet and/or humid environment, and that is configured to allow radio frequency (RF) reception and transmission by electronics within the enclosure. In an example of the enclosure, a plurality of layers interact synergistically to provide protection against moisture and a plurality of low cost antennas are disposed proximate an exterior of the enclosure. In the example, a foil layer of the enclosure defines a small opening, through which RF and electrical coupling occurs. The coupling ensures electrical connection to the antenna(s), defined in a layer proximate an exterior of the enclosure.
