Patent number: 8666451Abstract: A wireless communication system comprising at least one base station in a communication cell, wherein the base station is equipped with at least one array antenna comprising at least two antenna ports which are connected to respective at least two corresponding antenna elements, wherein at least two of the at least two antenna elements have essentially the same polarization. The array antenna is arranged for communication via at least two antenna radiation lobes, each antenna radiation lobe communicating an information stream to at least one user equipment (UE) in the cell, wherein each antenna radiation lobe is individually controllable both in azimuth and elevation, whereby the communication of the information streams is optimized.Type: GrantFiled: November 22, 2011Date of Patent: March 4, 2014Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Anna Barbro Ulrika Engström, Bo Göransson, Martin Nils Johansson, Mats H Andersson, Sven Oscar Petersson, Sven Anders Gösta Derneryd

Patent number: 8457697Abstract: An antenna arrangement comprising an input/output connection and a first and a second tuning network with different transfer functions. The arrangement additionally comprises an antenna and a switch for connecting the input/output connection of the arrangement to one of said tuning networks, with a second switch for connecting the antenna of the arrangement to the tuning network to which the input/output connection of the arrangement has been connected. The arrangement comprises a sensor for sensing a form factor of the arrangement or of an apparatus in which the arrangement is used, and said sensor can be used for influencing said first and second switches, so that a device which has been connected to the arrangement may be connected to the antenna via a tuning network optimal for the current form factor of the arrangement.Type: GrantFiled: November 14, 2007Date of Patent: June 4, 2013Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Martin Johansson, Patrik Persson, Jonas Fridén, Sven Anders Gösta Derneryd, Anders Stjernman

Patent number: 8224271Abstract: An electronic device (200,300) comprising an antenna arrangement with first and second antenna groups with first (122, 142) and a second (124, 144) radiation elements. The first and second radiation elements in each group have first and second respective polarizations and gain, and said groups also comprise a beam forming network (126, 146) connected to the radiation elements of the group and to an output selector (150). The beam forming network (126, 146) of each antenna group uses the radiation elements (122, 124; 142, 144) in the group to create a radiation pattern (127, 147) with a polarization which is a composite of the first and second polarizations of the elements in the group, so that a first (127) and a second (147) radiation pattern of composite polarization is created. The output selector (150) selects or combines signals received by the two antenna groups as its output.Type: GrantFiled: December 21, 2007Date of Patent: July 17, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Patrik Persson, Martin Nils Johansson, Anders Stjernman, Sven Anders Gösta Derneryd, Jonas Fridén

Patent number: 6470174Abstract: A radio unit casing (401) for a portable radio unit with an integrated antenna array capable of operating in a satellite communication mode. The antenna array comprises a number of adjacent co-operating antenna array surfaces arranged to be conformaly integrated in the radio unit casing (401). The antenna array surfaces faces in a multitude of directions which gives the antenna array a wide scan volume. The surfaces of the antenna array comprise a number of interleaved transmit and receive antenna elements, e.g. circular formed patches, in multiplayer structure.Type: GrantFiled: September 30, 1998Date of Patent: October 22, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Henry Schefte, Sven Anders Gösta Derneryd, Jan Staffan Reinefjord

Patent number: 6218987Abstract: The invention relates to an apparatus and a method for simultaneously generating, with the same radio antenna apparatus (10), a number of narrow beams and a wide beam, covering substantially the same area covered by the individual pointed beams together. The radio antenna apparatus (10) comprises an antenna array (3) a Butler matrix (2) connected to the antenna array and a set of amplifying modules (1a, . . . 1h). The activation of each of the inputs (L1, . . . , L8) of the radio antenna apparatus corresponds to a radiation pattern characterized by a narrow beam with a high antenna gain from the antenna array (3). By simultaneously activating the beam ports with the same signal with suitable phase relationships a superimposition of the radiation patterns to which the activated beam port corresponds is achieved in such a way that a wide beam is generated. Since all amplifying modules (1a, . . .Type: GrantFiled: May 6, 1998Date of Patent: April 17, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sven Anders Gösta Derneryd, Sven Oscar Petersson
