Abstract:
1. A beam forming antenna module for a wireless backhaul network for LOS or NLOS wireless coupling of stationary nodes of the network , comprising: a wide aperture arrangement of a plurality of radiating elements, wherein the plurality of radiating elements are arranged in an array on a panel having a large horizontal to vertical aspect ratio, and operate to provide a beam which is narrow in an azimuth plane and wide in an elevation plane; each radiating element comprising a dual polarization radiating element coupled to respective first and second transmitters and receivers (transceivers) for excitation in two polarizations; a digital beam former coupled to the transceivers for sending or receiving modulated data to and from the transceivers; a plurality of modem tiles coupled to the digital beam former; and a switch for aggregating the capacity of the modem tiles and providing a single interface to the network; and wherein the respective first and second transceivers are mounted behind each radiating element, and digital signal processing elements of the digital beam former, modem tiles and switch are mounted on a board behind the panel.
