发明名称 HIGH EFFICIENCY THREE PORT CIRCUIT
摘要 A circuit (100) for processing radio frequency signals includes a substrate (50) where the circuit can be placed. The substrate can be a meta-material and can incorporate at least one dielectric layer (20, 30, or 40). The circuit such as a three port circuit and at least one ground can be coupled to the substrate. The dielectric layer can include a first region (40) with a first set of substrate properties and a second region (20) with a second set of substrate properties. Substrate properties can include permittivity and permeability. A portion (32 or 46) of the three port circuit can be selectively 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. The increased permittivities and/or permeabilities can reduce a size of the three port circuit and effect a change in a variety of electrical characteristics associated with the three port circuit.
