Patent number: 9438278Abstract: In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.Type: GrantFiled: February 21, 2014Date of Patent: September 6, 2016Assignee: Quintel Technology LimitedInventors: David Edwin Barker, Lance Darren Bamford, Peter Chun Teck Song, David Sam Piazza

Publication number: 20150195001Abstract: In one example, an antenna system includes a radio base station for transmitting an RF signal via a transmission port, an RF splitting means for receiving the RF signal from the radio base station and for splitting the RF signal into two component signals, and at least two antennas separated by a distance greater than one wavelength and connected to the RF splitting means for transmitting the respective component signals such that an inferometric radiation gain pattern is created. The radio base station communicates with at least one mobile terminal via a dispersive multi-path radio channel where an angular spread of RF energy between the at least two antennas and the at least one mobile terminal causes nulls of the inferometric radiation pattern across a range of angles to be reduced.Type: ApplicationFiled: January 6, 2015Publication date: July 9, 2015Inventors: DAVID EDWIN BARKER, Lance Darren Bamford, Peter Chun Teck Song, Brent Irvine

Patent number: 6876334Abstract: Disclosed are systems and methods which provide a tapered conductor strip adapted for broadband wireless communication. Embodiments provide a conductor strip which is curved along its face, thereby providing an aperture taper. The conductor strip configured to provide an aperture taper may be placed over a planar ground plane to form a wideband tapered strip antenna element.

Publication number: 20040146013Abstract: A time division duplex repeater system includes two antennas, a switched directional amplifier and control circuitry. The antennas serve first and second coverage areas where the second coverage area is an extension of the first coverage area. The switched directional amplifier is coupled between the two antennas and has a single amplifier. The control circuitry is coupled to the switched directional amplifier and to receive inputs of the antennas. The control circuitry receives transmissions from the coverage areas and applies control signals to the switched directional amplifier to control the direction of transmission. The control circuitry may control the amplifier gain and direction of transmission based on the input signal power level.Type: ApplicationFiled: January 22, 2003Publication date: July 29, 2004Applicant: Hong Kong Applied Science and Technology Research Institute Co., LtdInventors: Peter Chun Teck Song, Ross David Murch, Hang Ching Jason Leung, Wai Yuk William Tao
