Patent ID: 8025625

Claim:
An apparatus comprising: a monolithic body of substantial uniformity formed by thermal bonding defining a hermetic chamber having an upper wall and an opposed lower wall; a first conductive structure disposed within said hermetic chamber, said first conductive structure comprising a distributed LC circuit, wherein a first portion of said distributed LC circuit is fixed to the upper wall of the chamber, and wherein a second portion of said distributed LC circuit is positioned oppositely disposed and substantially parallel to the first portion of said distributed LC circuit and is fixed to an upper surface of the lower wall of the chamber; a second conductive structure fixedly disposed on a bottom surface of the lower wall outside said hermetic chamber in spaced, substantially parallel opposition to the second portion of said distributed LC circuit of said first conductive structure; and means physically attached to the lower wall of said hermetic chamber for at least partially enclosing and isolating said second conductive structure; wherein said first conductive structure is electromagnetically coupled to said second conductive structure without direct electrical paths connecting said first and second conductive structures.
