摘要： An N-element rotational-symmetric array antenna can generate N fixed pencil-beams simultaneously with an omnidirectional beam. An N x N Butler matrix can be used to feed the array antenna, using fewer than N input ports of the Butler matrix to produce the pencil-beams. One or more of the modes generated by the Butler matrix can be individually accessed to produce one or more corresponding omnidirectional beams. The N x N Butler matrix can be driven by a feed network that provides both power dividing and beam-steering, which permits simultaneous generation of the N pencil-beams.

摘要： The invention discloses a wireless telecommunications system (200) for stationary or semi-stationary equipment, and comprises a main node (C) and a first plurality (S1-S3) of terminals belonging to the same access subset and arranged to receive from and transmit to the main node (C). The main node transmits in at least one beam (110) and receives in at least two beams (111-113), and the system comprises means (C) for indicating to terminals (111-113) that they may or may not transmit to the central node (C). Based upon certain criteria, two or more terminals (Si-SN) located in different receive beams (111-113) of the main node (C) may be given permission to transmit to the central node simultaneously. Suitably, two or more terminals which are given permission to transmit simultaneously do so using the same frequency, or the same code or the same time slot.

摘要： A device for microstrip distribution networks and for group antennas for the suppression of unwanted modes on the distribution network side of a microstrip distribution network. This thereby avoids, among other things, unwanted coupling between antenna elements (120, 220, 317, 520, 620) connected to the microstrip distribution network. A waveguide substructure (100, 200, 300, 400), in principle designed as a U of extruded aluminium, is connected to the microstrip distribution network along two connection lines (101, 201, 301, 401) with at least two electrically-conductive connections (111, 211, 311, 411) to the ground plane (116, 216, 316, 416) of the microstrip distribution network along each connection line. Together with at least part of the ground plane, the waveguide substructure forms a waveguide structure. The waveguide structure is dimensioned so that it has a cut-off frequency that is higher than the highest frequency that is used in the microstrip distribution network. This suppresses unwanted modes generated by the group antenna and by discontinuities in the distribution network as the waveguide structure acts as a high-pass filter.
