    Abstract: A slot fed microstrip patch antenna (300) includes a conducting ground plane (308), the conducting ground plane (308) including at least one slot (306). A dielectric material is disposed between the ground plane (308) and at least one feed line (317), wherein at least a portion of the dielectric layer (313 ) includes magnetic particles (324). The dielectric layer between the feed lin e (317) and the ground plane (308) provides regions having high relative permittivity (313) and low relative permittivity (312). At least a portion o f the stub (318) is disposed on the high relative permittivity region (313).

    Abstract: A slot fed microstrip patch antenna (200) includes an electrically conducting ground plane (208), the ground plane (208) having at least one coupling slot (206) and at least a first patch radiator (209). An antenna dielectric substrate material (205) is disposed between the ground plane (208) and the first patch radiator (209), wherein at least a portion of the antenna dielectric (210) includes magnetic particles (214). A feed dielectric substrate (212) is disposed between a feed line (217) and the ground plane (208). Magnetic particles can also be used in the feed line (217) dielectric. Patch antennas according to the invention can be of a reduced size through use of high relative permittivity dielectric substrate portions, yet still be efficient through use of dielectrics including magnetic particles which permit impedance matching of dielectric medium interfaces, such as the feed line (217) into the slot (206).

    Abstract: 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.

    Abstract: A circuit for processing radio frequency signals. The circuit includes a substrate (102) 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 (106) and at least one ground can be coupled to the substrate (102). The dielectric layer can include a first region (102) with a first set of substrate properties and a second region (104) with a second set of substrate properties. Substrate properties can include a permittivity and a permeability. A substantial portion of the quarter-wave transformer (106) can be coupled to the second region (104). The permittivity and/or permeability of the second region (104) can be higher than the permittivity and/or permeability of the first region (102).
