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 method for applying a protective coating to an electro-optical component includes positioning the electro-optical component in a chamber (step 32) and applying a coating composition (step 35) to at least one surface of the electro-optical component to form the protective coating thereon. The coating composition may include fluorinated poly (phenylene ether ketone) and an anti- reflection agent. The anti-reflection agent may include at least one of an inorganic salt, an organofunctionalized additive, and an erbium dopant, for example.

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: An RF filter (120) that includes a substrate (100) having a plurality of regions (102,104,106), each having respective substrate properties including a relative permeability and a relative permittivity. At least one filter section (112,114) is coupled to one of the regions of the substrate which has different substrate properties in comparison to other regions. Other filter sections can be coupled to other substrate regions having different substrate properties. The permeability and/or permittivity can be controlled by the addition of meta-materials to the substrate and/or by the creation of voids in the substrate. The RF filter can be a stepped impedance filter. One filter section includes a transmission line section having an impedance influenced by the region of the substrate on which the filter section is disposed. The transmission line section construction can be a microstrip, buried microstrip, or stripline. A supplemental layer of the substrate can be disposed beneath the filter section.

Abstract: A printed circuit for processing radio frequency signals. The printed circuit includes a substrate. The substrate can be a meta material and can include at least one dielectric layer. The dielectric layer can have a first set of dielectric properties over a first region and a second set of dielectric properties over a second region. The dielectric permittivity and/or magnetic permeability of the second set of dielectric properties can be different than the first set of dielectric properties. The printed circuit also can include a single port resonant line and a ground coupled to the substrate. The dielectric properties can be controlled to adjust the size of the resonant line. The dielectric properties also can be controlled to adjust an impedance, quality factor and/or capacitance on the resonant line. Resonant characteristics of the resonant line can be distributed through the substrate.
