Abstract
A loop antenna includes a dielectric substrate, and an antenna conductor forming a loop that extends over a surface of the substrate. A matching circuit near the conductor is dimensioned and arranged for electromagnetically coupling a radio frequency circuit with the antenna conductor. In one embodiment, the antenna conductor forms a closed loop on a surface of a first substrate layer, and the matching network includes a strip transmission line on a surface of a second substrate layer overlying the antenna conductor on the first substrate layer. The substrate layers form part of an interface unit that provides a wireless data link with a residential electric utility meter.
