    摘要: A multi-facetted antenna array is disclosed for omnidirectional signalling. The multi-facetted antenna array includes a plurality of abutting facets having a planar region under the patch antenna structures, and curving regions between the planar regions and across the abutting edges of the facets. The planar regions under the patch antenna provide proper RF antenna performance, while the curved regions minimize the size of the assembled array. Further disclosed is a method of mounting the associated RF interface module across an inside corner formed by abutting facets. The disclosed multi-facetted antenna array is particularly useful for overcoming the unsightly size and wind loading problems of multi-facetted antenna arrays known in the art.

    摘要: The invention provides a multiple beam antenna and a method of fabricating such an antenna. The multiple beam antenna comprises: a flexible substrate having a conductive layer; a plurality of directional antennas; and a plurality of electrical connections being routed from each of the plurality of directional antennas to at least one area of the substrate. The plurality of directional antennas and the plurality of electrical connections are formed in the conductive layer, and the flexible substrate is shaped so that the plurality of directional antennas point in prescribed directions. This provides a low cost, high functionality multiple beam antenna. The multiple beam antenna can be shaped such that the directional antennas cover a full 360° or alternatively cover any range of other angles, (e.g. 270° or 180°).

    摘要: Optical assemblies of the type supported on an optical bench and comprising a one or more components such as lasers, lenses, filters, isolators and waveguides, are sensitive to movement variation. One of the causes of movement is temperature tracking. Previously, thermo-electric coolers have been used to maintain the top-surface temperature of an optical bench within a certain range. However, although thermo-electric coolers are operable to maintain optical bench temperature they are themselves still sensitive to temperature tracking and can deform. Because an optical bench is typically supported on the top surface of a thermo-electric cooler this leads to deformation of the optical bench itself and as a result performance of the optical assembly is affected. An improved design of thermo-electric cooler is described where the top surface of the cooler is divided into separate regions, each having a neutral region in which deformation is minimal. A thermally conductive sheet is placed over each of these regions such that only one temperature monitor is required. Optical components are then supported over the thermally conductive sheet in the neutral regions.
