摘要： A method and apparatus for increasing capacity and performance of a base station for a sectorized cellular wireless network is disclosed in which one of the sector antennas is replaced or supplanted by a novel sub-sector antenna that generates a plurality of asymmetrical sub-sector coverage areas that collectively substantially cover the coverage area of the replaced sector antenna. The use of asymmetrical coverage areas permits the total coverage area to closely approximate the symmetrical sector coverage area without creating excessively large sub-sector handover zones or introducing severe degradation in the network performance. This in turn permits the selective replacement of a single sector antenna rather than the wholesale replacement of all sector antennas in a region, leading to lower transitional costs and the ability to provide a focused approach to capacity planning.

摘要： A patch radiator for use in beamformed or steerable antenna systems which maximizes upper frequency limit and simultaneously minimizes the lower frequency limit, by providing an annular patch configuration in which a central region of the patch element is devoid of material, whereby this central region is of a different shape from the shape of the exterior perimeter of the patch element. One possible configuration of such a patch radiator comprises a square exterior shape, enclosing a central circular region of removed material. In this manner, the upper frequency limit threshold tends to rise as the interior annular perimeter is reduced. Preferably, the exterior and interior perimeters have no interior angles of more than 180°.

摘要： A smart antenna for a base station comprises a plurality of antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the totality of beams formed by the arrays provides a substantially omni-directional coverage in azimuth A plurality of r.f. transceivers is provided each for transmitting and receiving r.f. signals for one or more calls, with switching matrix means for connecting each transceiver with one or other of the arrays via beamformers. Each transceiver is connected by a switch matrix to a particular array to exchange r.f. signals with a remote station located in the area covered by one of the narrow overlapping beams. Means are provided for selecting for a given call more than one of the best received signals from the multiplicity of narrow overlapping beams and the selected signals are combined to form a single receive signal input for the r.f. transceiver for the given call.

摘要： An antenna for a base station comprising a plurality of antenna arrays (40; FIG. 6a) each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams formed by the arrays provide a coverage in azimuth wider than each array. Means are provided for operating (FIG. 12a, FIG. 12b) two or more non-collocated narrow beamwidth antenna arrays to form jointly a broad beamwidth antenna radiation pattern wherein the time averaged antenna pattern is substantially null free.
