Patent number: 7898489Abstract: The present invention relates to a device for adjusting the beam direction of a beam radiated from a stationary array of antenna elements. Antenna element feed points are coupled to a common source via a feed line structure having a source connection and feed connection terminals to be connected to the antenna element feed points, the feed line structure being at a distance from and in parallel to a fixed ground plane. A movable element is located adjacent to the feed line structure to change the signal phase of signal components being transferred between the source connection and the respective feed connection terminals. The movable element is movable for effecting a phase shift of the signal components to adjust the beam direction. The device is provided with a detection arrangement for detecting the absolute position of the movable element.Type: GrantFiled: May 31, 2006Date of Patent: March 1, 2011Assignee: Powerwave Technologies Sweden ABInventors: Jarmo Mäkinen, Olov Ekervik, Daniel Åkesson, Tord Liljevik, Johan Dagerhamn, Erik Östlind

Publication number: 20110012798Abstract: A system for use with vehicle-based wireless multiple-input multiple-output (MIMO) communications equipment has several directional sub-arrays mounted on different faces of the vehicle. It is contemplated in typical operation that each sub-array will experience different channel conditions that can be evaluated with the help of pilot tones or training sequences transmitted from a remote communications device. Based on channel rank, or other appropriate metric, the system selects the sub-array with the best predicted performance for communication with the remote device. The system achieves better MIMO performance while contributing less interference to other nearby co-channel users and allows full use of the limited number of MIMO antenna elements supported by conventional 4G wireless standards.Type: ApplicationFiled: January 21, 2010Publication date: January 20, 2011Applicant: Telcordia Technologies, Inc.Inventor: Anthony Triolo
