Abstract
A circuit for processing radio frequency signals. The circuit includes a substrate where the circuit can be placed. The substrate can be a meta material and can incorporate at least one dielectric layer. A quarter-wave transformer and at least one ground can be coupled to the substrate. The dielectric layer can include a first region with a first set of substrate properties and a second region with a second set of substrate properties. Substrate properties can include a permittivity and a permeability. A substantial portion of the quarter-wave transformer can be coupled to the second region. The permittivity and/or permeability of the second region can be higher than the permittivity and/or permeability of the first region.
