1. A circuit comprises:
- a printed inductor;
a printed antenna; and
a substrate that supports the printed inductor in a first region of the substrate with non-magnetic metallodielectric inclusions and the printed antenna in a second region of the substrate with high permittivity metallodielectric inclusions, separate from the first region and wherein the substrate further includes a third region outside the first region and the second region, wherein the first region has a higher permeability relative to the third region and the second region has a higher permittivity relative to the third 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.

9. An antenna circuit comprises:
-
a programmable frequency selective surface having a semiconductor material and having metallodielectric inclusions embedded in the semiconductor material that contribute to an electromagnetic characteristic; a high impedance surface having a surface substantially parallel to, and at a distance from, the programmable frequency selective surface; an antenna source that radiates an electromagnetic signal, wherein the electromagnetic signal reflects off of the high impedance surface and radiates through the programmable frequency selective surface; and one or more variable impedance circuits that tune the electromagnetic characteristic of the programmable frequency selective surface for desired performance of the antenna circuit. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An antenna circuit comprises:
-
a substrate; an antenna printed on a single surface of the substrate, wherein the antenna is positioned in a region of the substrate that has a high permittivity relative to areas of the substrate outside of the region, wherein the region of the substrate includes metallodielectric inclusions embedded in substrate material in the region of the substrate; a projected artificial magnetic mirror (PAMM) that produces an artificial magnetic conductor (AMC) at a distance above a surface of the substrate to facilitate a radiation pattern for the antenna; and a control module configured to control a shape of the AMC via one or more variable impedance circuits by tuning a permittivity of the region of the substrate that has the high permittivity. - View Dependent Claims (17, 18, 19, 20)
