Abstract: An antenna (100,200,300, 400, 500) comprising first (110, 210, 310, 410, 430) and second (120, 220, 320, 420, 440) structures for guiding electromagnetic waves, each comprising groups (111, 130, 150, 230, 330; 140,160, 240, 340, 445, 470) of radiation elements. For adjacent sections in 5 the structures, at least one applies: ?Groups of radiation elements are distributed along the two structures such that a group (110, 130, 150) in the first structure overlaps a group (120, 140,160) in the second structure partially or not at all. ?Radiation elements within said groups (230; 240) exhibit a common 10 main direction of extension within the group, and differs between the first and the second groups by an angle of at least 10 degrees. ?The radiation elements of the groups (330, 340) are distributed along the structures (310, 320) on sides of the structures which face different directions.

Abstract: The present invention relates to an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means for transmitting and receiving signals to/from a number of user stations. A feeding network is provided which comprises a number of phase ports, a number of which form first phase ports connected to a number of transceiver means for downlink communication and a number of which form second phase ports connected to a number of transceiver means for uplink communication. The feeding network comprises a number of antenna ports connected to antenna elements and the feeding network generates substantially independent, orthogonal signals to provide for phase diversity and the antenna elements are arranged to form at least one cylindrical array antenna. The invention also relates to a method of providing communication between an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means and a number of user stations as well as to a method of providing for at least phase diversity transmission at an omnidirectional base station antenna arrangement.

Abstract: The present invention discloses an antenna device and system design forming a modular common antenna surface having various surface portions for transmission and reception as well as integrated transmission and reception within the same common antenna surface, the various surface portions either forming passive or active arrays for transmission or reception. Additionally superimposed surface portions of the modular common antenna surface constitute individual transmit and receive array portions, respectively, sharing the total aperture, the modular common antenna surface producing at least one polarization plane for transmission and generally two orthogonal polarization planes for reception to achieve polarization diversity for the reception. Further the antenna surface of the device and system according to the invention generally form a microstrip module array containing a number of radiation element for transmission and/or reception, and consist of one or several columns of individual element forming the antenna aperture, the column and/or columns additionally in the preferred arrangement having integrated power amplifiers and/or low noise amplifiers (LNA:s), respectively.

Abstract: An antenna unit transmit and receives radio signals having two different polarizations. The antenna unit includes a slot integrated in a microstrip element and an aperture integrated in a conductive surface on the microstrip element. The aperture is arranged in the conductive surface parallel to its polarization direction. The slot is arranged in an underlying layer directly below the aperture. The conductive surface of the microstrip element is arranged to transmit or receive with a vertical polarization and a first horizontal beam width. The slot is arranged to transmit or receive with a horizontal polarization and a second horizontal beam width. The second beam width is substantially equal to the first beam width. The antenna unit is very compact and light and only causes low power losses. A number of antenna units can be used to design sector antennas or antenna arrays.
