Patent number: 10424830Abstract: 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 or 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 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.Type: GrantFiled: March 6, 2017Date of Patent: September 24, 2019Assignee: Intel CorporationInventors: Kostyantyn Semonov, Alexander Rabinovich, Bill Vassilakis

Patent number: 9972906Abstract: An assembly for a mobile communications antenna system includes a bracket assembly onto which an antenna array is mounted. The bracket assembly includes a steering arrangement configured to provide angular adjustment of an antenna beam azimuth, and an electromechanical tilting arrangement configured to adjust a tilt position of the antenna array. The steering arrangement and the electromechanical tilting arrangement are controllable in remote and manual operational modes to independently and variably adjust both azimuthal angle and tilt position of the antenna array. These operational modes ensure remote control of signal propagation and network coverage accuracy, and manual adjustment of the azimuth of the antenna beam and tilt position of the antenna array in case of field service or component failure.Type: GrantFiled: January 14, 2016Date of Patent: May 15, 2018Assignee: OUTTHINK TECHNOLOGIES, LLCInventor: Bill Vassilakis

Patent number: 8446327Abstract: 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.Type: GrantFiled: January 28, 2009Date of Patent: May 21, 2013Assignee: Powerwave Technologies, Inc.Inventors: Bill Vassilakis, Nikolai Maslennikov, Alexander Rabinovich

Publication number: 20120268324Abstract: 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.Type: ApplicationFiled: June 26, 2012Publication date: October 25, 2012Inventors: BILL VASSILAKIS, SENGLEE FOO
