Patent ID: 7055754

Claim:
A wireless communication system in combination with a dielectric material, comprising: the dielectric material; the wireless communication system mounted in electrical proximity to the dielectric material, comprising: a wireless communication device; an antenna system comprising at least one conductive tab, including one or both of the following: (a) a plurality of electrical components selected to form an impedance matching network, coupled to said at least one conductive tab and said wireless communication device wherein the electrical components electrically interact with the dielectric material to maintain a substantial impedance match between the antenna system and the wireless communication device; and, (b) a structural element forming a frequency selective by-pass trap circuit formed in said conductive tab and electrically interacting with the dielectric material to maintain a substantial impedance match between the antenna system and the wireless communication device; wherein the one or both of the plurality of electrical components and the structural element are configured to self-compensate for different electrical characteristics of different dielectric materials, through electrical cross-coupling of conductive parts of the antenna system, to maintain the substantial impedance match for different dielectric materials.
