| 20090079653 | BROADBAND COPLANAR ANTENNA ELEMENT - 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. | 03-26-2009 |
| 20090096698 | Omni directional broadband coplanar antenna element - 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. | 04-16-2009 |
| 20090096702 | DUAL BEAM SECTOR ANTENNA ARRAY WITH LOW LOSS BEAM FORMING NETWORK - A low loss beam forming method and antenna structure are disclosed. The method and structure may preferably be used in forming two narrow beams within a cellular sector. This method allows an increase in the overall network capacity by using a three-column non-planar array and a compact, low-cost, low-loss 3-to-2 Beam-Forming Network (BFN). This structure produces two symmetrical beams with respect to the azimuth boresight. Radiation patterns of the two beams are designed to cover the entire azimuth coverage angle of a cellular sector with minimum beam-split loss and cross-over losses. | 04-16-2009 |
| 20090195467 | COMPOUND TWO-WAY ANTENNA WITH INSTALLATION COMPENSATOR - 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. | 08-06-2009 |
| 20100109965 | LOW POWER MULTI-BEAM ACTIVE ARRAY FOR CELLULAR COMMUNICATIONS - An antenna architecture with enhanced emission directivity is disclosed. The antenna comprises a dielectric structure positioned over a plurality of radiator elements. The dielectric structure comprises columns of dielectric disks positioned above each radiator element. The antenna is driven by beam forming networks to form multiple, simultaneously steerable beams or a single main beam that can be dynamically steered. | 05-06-2010 |
