    Abstract: An antenna can be joined to an antenna feed and positioned perpendicular to a ground plane. The antenna includes a conductive radiator having a cylindrical portion. A slot is formed in the entire length of the cylindrical portion. Two parallel fins extend from the cylindrical portion at the slot. The fins can extend inwardly or outwardly. The antenna feed is connected to the conductive radiator on either side of the slot. An anisotropic magnetic material having a uniaxial permeability tensor is positioned in the slot between the two fins. This material is oriented such that it has a much greater permeability in the radial direction than in the other directions. The interior of the cylindrical portion can be filled with a dielectric material.

    Abstract: A waveguide transmitting an electromagnetic wave having an electric field that oscillates in a first direction in a second direction perpendicular to the first direction. The waveguide includes rectangular waveguide portions, and a protruding wall and a retracted wall that connect a rectangular waveguide portion to another rectangular waveguide portion. Each of the rectangular waveguide portions has a tubular shape extending in the second direction, and an inner wall of each rectangular waveguide portion has a rectangular cross section. The rectangular waveguide portions are arranged in the second direction, and inner spaces of the rectangular waveguide portions are connected to each other. The protruding wall extends from one of a pair of side surfaces of the rectangular waveguide portion opposed in a third direction toward the other of the pair of side surfaces, the third direction being perpendicular to the first and second directions.

    Abstract: Recovery of hydrocarbons, such as petroleum products, from a liquid or solid substrate is facilitated by the use of microwave energy to energize and separate molecular bonds between the hydrocarbons and the substrate. A radio frequency (RF) applicator delivers microwave energy to a treatment volume containing an emulsion of a hydrocarbon and a substrate. Delivering the microwave energy to the emulsion facilitates separation of the hydrocarbon and substrate molecules into layers. Hydrocarbons and other products can then be recovered from their respective layers. The treatment volume may be located either above or below ground. The RF applicator may include an antenna body with slots formed substantially parallel to one another in a substantially horizontal orientation. The RF applicator efficiently delivers microwave energy into the treatment volume. Substantially all of the power supplied to the RF applicator is radiated, with very little power reflected internally within the RF applicator.

    Abstract: An antenna (100) for RF communications. The antenna includes a radiating member (102) which is substantially tubular so as to define a cavity (104) therein. The radiating member (102) is made of a conductive material having a non-conductive slot (106) extending from a first portion (108) of the radiating member (102) to a second portion (110). An impedance matching device (120) is electrically connected to the radiating member (102) via a conductor (134) to match an impedance of the radiating member (102) with an impedance of a signal source or an impedance of a load. The impedance matching device (120), the conductor (134), and at least a portion of the radiating member radiating element (102) can formed from a single conductive sheet, or molded or extruded as a single conductive structure.
