摘要： The present invention relates to a wireless communication arrangement comprising a node and a leaky cable running between a first and second converter arrangement. The first converter arrangement connects a first downlink signal and a second downlink signal to the cable, and converts the second downlink signal from a first frequency to a second frequency. The cable's other end is connected to the second converter arrangement which converts the second downlink signal from the second frequency to the first frequency. The second converter arrangement also converts a first uplink signal from a third frequency to a fourth frequency. The first converter arrangement receives the converted first uplink signal from the second converter arrangement and converts it from the fourth frequency to the third frequency. The first frequency is separated from the second frequency, and the third frequency is separated from the fourth frequency.

摘要： An antenna arrangement comprising at least two antenna arrays (M, M', M'), each array comprising a plurality (N) of radiating elements (R) being arranged so as to have at least a plurality of corresponding radiating element positions, wherein for each radiating element there is associated an excitation means (E) comprising a magnitude weight (A) and a delay weight (α), wherein there is a first set (SE) of excitation means (E) associated with a first array (M) providing a first radiation pattern and a second set (SE') of excitation means (E) associated with a second array (M') providing a second radiation pattern. At least two respective excitation means (E) associated with a corresponding radiating element position of at least two respective arrays (M, M', M') have at least two different magnitude weights (An, A'n, A'n), and at least two respective excitation means (E) associated with a corresponding radiating element position of at least two respective arrays (M, M', M') have at least two different delay weights (αn, α'n, α'n). The excitation weights (An, A'n, A'n; αn, α'n, α'n) of the at least first and second sets of excitation means (SE, SE') are selected so that the main beam directions of the at least two antenna arrays essentially coincide and so that at least the magnitude of the correlation coefficient (p) associated with respective signals (S, S') communicated over the at least first and second array (M, M', M') is below 0.7 in a given side-lobe region, or so that the radiation amplitude patterns (P, P') associated with the at least first and second set of excitation means have an envelope with a substantial null-fill difference in a given side-lobe region with regard to the main beam peak.

摘要： A multi beam antenna arrangement has antenna elements arranged to form an antenna array with a first end and an opposite second end, and at least one beam-forming matrix having antenna ports connected to the antenna elements. The antenna arrangement is configured to generate multiple orthogonal antenna beams. The beam-forming matrix comprises at least two antenna ports with a predetermined order and phase relation and a plurality of beam ports. The at least two antenna ports are fewer in number than the plurality of antenna elements. A subgroup of the antenna ports is connected to at least two of the plurality of antenna elements via at least one splitter/combiner arrangement, to enable dividing a power supplied by the antenna port to the at least two antenna elements or by combining a respective power received on the at least two antenna elements.

摘要： 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.

摘要： The present invention relates to a node (1) in a wireless communication network (2). The node (1) comprises an antenna arrangement (3) which in turn comprises an array antenna (4). The array antenna comprises a first set of antenna elements (5) forming a first antenna aperture (6), and a second set of antenna elements (7) forming a second antenna aperture (8). The antenna arrangement (3) further comprises a switching arrangement (22) that is adapted to switch between a first mode of operation (M1) and a second mode of operation (M2). In the first mode of operation, the first antenna aperture (6) is arranged to generate a first antenna beam (9). In the second mode of operation, the first antenna aperture (6) and the second antenna aperture (8) are combined and arranged to generate a second antenna beam (10), the first antenna beam (9) having a wider antenna beamwidth than the second antenna beam (10). The present invention also relates to a corresponding method.
