    摘要： A treatment system for treating water, such as produced water that is produced during hydraulic fracturing. The system employs a combination of a plasma spark discharge and an RF oscillating electric field. The plasma spark discharge and the RF oscillating electric field may be employed simultaneously or in an overlapping manner within a chamber to treat the water. The treatment system is able to kill microorganisms as well as reduce or eliminate fouling due to, for example, bicarbonates. In some embodiments, grids are employed to further enhance the heat produced by the RF oscillating electric field.

    摘要： A two-way terrestrial antenna, employing electrical down tilt and azimuth beam adjustment capability is disclosed. Such antenna configuration allows for a variable antenna coverage footprint within designated coverage sector. To compensate for installation support structure variations the two-way antenna employs a positional sensor that can provide feedback to BTS or automatically compensate azimuth and tilt beam angles so as to provide uniform sector coverage. In particular by monitoring tri-vector gravitational inclinometer and earth magnetic field sensors, and determining correction factors for antenna tilt and azimuth beam adjustments, uniform or compensated sector coverage is provided.

    摘要： The present invention provides an omni-directional antenna element configuration having a compensated radiation pattern. Broadband antenna elements are coplanarly disposed on a suitable planar dielectric material. A single element omni-directional antenna comprises a pair of balanced fed radiating microstrip elements symmetrically disposed about the centerline of a balanced signal feed network. Additionally, a pair of pattern augmentation rods are positioned on each side of and proximate to the planar dielectric material running longitudinally to the centerline axis of a balanced feed network. Disposed proximate to each radiating element are partially coplanar, frequency bandwidth expanding microstrip lines. The combination of radiating elements together with pattern augmentation rods provides a broad bandwidth omni-directional radiating element suitable for use in multi-element antenna arrays.

    摘要： A broadband antenna element configuration having a radiation pattern useful in an antenna array containing a plurality of driven radiating elements that are spatially arranged is disclosed. The antenna element is coplanarly disposed on a suitable planar substrate of dielectric material. The antenna element utilizes a pair of balanced dipole arm elements symmetrically disposed about the centerline of a balanced feed network. Balanced feed network elements are disposed in a broadside symmetrical configuration on first plane and second plane on each side of the aforementioned dielectric. Disposed proximate to each dipole arm element are partially overlapping, parallel planar, frequency bandwidth expanding microstrip lines. The combination of dipole arms and parasitically coupled microstrip lines provides a broad bandwidth radiating element suitable for use in antenna arrays.
