Patent number: 9014068Abstract: An antenna having a passive feed network in one band, and an active radio network in an adjacent band, is provided. The antenna includes radiating elements arranged in an array dimensioned to transmit and receive RF signals. The antenna includes diplexers having a first port, a second port and a third port. The first port of each diplexer coupled to at least one radiating element. The diplexer has a first filter coupling the first port to the second port and a second filter coupling the first port to the third port. A passive feed network includes a phase shifter, which is coupled to an input transmission line and a plurality of output transmission lines. Each of the output transmission lines may be coupled to one of the second ports of one of the diplexers. An active radio is coupled to each of the third ports of the plurality of diplexers.Type: GrantFiled: October 11, 2011Date of Patent: April 21, 2015Assignee: CommScope Technologies LLCInventors: Kevin Eldon Linehan, Jonas Aleksa, Martin Weckerle

Patent number: 8018390Abstract: A cellular communications antenna including sensors for determining position and/or orientation of the antenna. Position information may be obtained using, for example, a GPS receiver or by triangulation. Orientation information may be obtained using, for example, an electronic compass and/or gyroscope and/or an inclinometer. Position and/or orientation information may be utilised locally to control attributes of the antenna or may be communicated to a central controller which may control attributes of the antenna. Signals may be sent to a central controller to indicate that an attribute of the antenna is outside a desired range.Type: GrantFiled: July 18, 2006Date of Patent: September 13, 2011Assignee: Andrew LLCInventors: Darren Davidson, Philip Sorells, Bobby Webb, Kevin Eldon Linehan, Louis John Meyer

Patent number: 7688271Abstract: A dipole antenna comprising a base; first and second pairs of dipoles positioned in front of the base and arranged around a central region; a first feed line which extends from the base towards the dipoles and splits at a first junction positioned in front of the base into a first pair of feed probes each of which is coupled to a respective one of the first pair of dipoles; and a second feed line which extends from the base towards the dipoles and splits at a second junction positioned in front of the base into a second pair of feed probes each of which is coupled to a respective one of the second pair of dipoles. The feed probes are spaced from the dipoles so as to field-couple with the dipoles. In one embodiment, the first pair of feed probes is positioned on a first side of the dipoles and the second pair of feed probes is positioned on a second side of the dipoles opposite to the first side. In another embodiment, the dipoles are printed on a PCB.Type: GrantFiled: April 18, 2006Date of Patent: March 30, 2010Assignee: Andrew LLCInventors: Huy T. Cao, Kevin Eldon Linehan, Martin L. Zimmerman, Xiangyang Ai

Patent number: 7639196Abstract: There is provided a cellular antenna allowing mechanical azimuth adjustment in combination with adjustment of one or more other antenna attribute such as electrical down tilt, electrical beam width or electrical azimuth adjustment. An integrated control arrangement is provided which can utilise either serial, wireless or RF feed lines to convey communications. A multiband embodiment provides azimuth adjustment for both bands by utilising mechanical and electrical azimuth adjustment. Systems incorporating such antennas and methods of controlling them are also provided.Type: GrantFiled: April 6, 2006Date of Patent: December 29, 2009Assignee: Andrew LLCInventors: Robert Douglas Elliot, Martin L.

Patent number: 6922169Abstract: A power coupler including a differential phase shifter for differentially adjusting the relative phase between signals on a pair of signal lines; and a hybrid coupler which is coupled to the pair of signal lines. The power coupler may be employed in an antenna including first and second signal lines; a differential phase shifter for differentially adjusting the relative phase between signals on the first and second signal lines; a first set of one or more radiating elements; a second set of one or more radiating elements; and a hybrid coupler having a first port coupled to the first signal line, a second port coupled to the second signal line, a third port coupled to the first set of radiating elements, and a fourth port coupled to the second set of radiating elements. Elevation beam width is adjustable independently of azimuthal beam width.Type: GrantFiled: February 14, 2003Date of Patent: July 26, 2005Assignee: Andrew CorporationInventors: Narian Moh'd Kheir Moh'd Izzat, Martin Lee Zimmerman, Kevin Eldon Linehan
