The present invention relates to integral antenna assemblies and in particular relates to an integral antenna assembly for microcellular base stations and fixed wireless access base stations. In accordance with one aspect of the invention, there is provided an integral antenna comprising a radome, a layered antenna and a reflector back plane, wherein the layered antenna has an outer surface and a rear surface; wherein the radome is attached directly to an outer surface of the antenna; and wherein the back plane provides a reflective cavity and encloses the feed network for the antenna and is attached to the rear surface of the antenna. In accordance with another aspect of the invention there is provided method of operating an integral antenna comprising a radome, a dielectric substrate having a patch antenna element on a surface thereof and a reflector back plane providing a reflective cavity behind the radiating element; wherein the radome is attached directly to an outer surface of the dielectric and the reflector back plane is attached to a rear surface of the dielectric, the patch being connected through the substrate to a microstrip feed line, whereby the microstrip feed line lies parallel to the patch, with the patch acting as a ground with respect to the microstrip line, wherein the antenna transmits and receives signals via the feed network.

Antenna assembly

A ribbon cable assembly for interconnection to an electronic equipment pull-out drawer which is arranged so as to occupy a minimum of depth within the drawer while effectively preventing kinking or tangling of the cables as the drawer is opened and closed. This is achieved by folding each of the cables back on themselves so that they individually connect to the back of the drawer at different elevations at connections which are in vertical alignment with one another. In addition the cables overlie each other so that their flat surfaces are orthogonal to the direction of movement of the pull-out drawer.

Ribbon cable assembly

A protection case for optical fiber splices is in the form of an elongate box having ducts along each side and a plurality of packet members pivotally attached to the bottom of the case in overlapping relationship. A holder in each packet will hold at least one splice, or an attenuator and two associated splices. A cover fastens over the base of the case. The packets have the form of shallow boxes and extra fiber is coiled around in a packet, being retained by turned in edges of the top, sides and bottom.
