1. A circuit comprises:
- an inductor;
an antenna; and
a substrate supporting the inductor in a first region of the substrate having non-magnetic metallodielectric inclusions and the antenna in a second region of the substrate, separate from the first region, having high permittivity metallodielectric inclusions, wherein the first region has a higher permeability relative to the second region and the second region has a higher permittivity relative to the first region.

Abstract
An antenna circuit includes a substrate, an antenna, and a projected artificial magnetic mirror (PAMM). The antenna is fabricated on the substrate and is positioned in a region of the substrate that has a high permittivity. The PAMM produces an artificial magnetic conductor at a distance above a surface of the substrate to facilitate a radiation pattern for the antenna.
