Abstract: A planar array antenna having a low-profile that provides a two dimensional, steerable, high-gain, low-sidelobe radiated RF beam patterns is presented. The antenna includes a metamaterial array of a plurality of first and second rows of unit cells, to propagate a radiation pattern along a first axis. The first rows operate in left-hand mode and the second rows operate in right-hand mode. Each of the unit cells include a volume of liquid crystal and a virtual ground connection capable of generating a potential difference for tuning the dielectric value of the liquid crystal. The antenna further includes a plurality of RF input ports disposed in a centralized location and a dual-channel center-feed network communicatively coupled to the plurality of paired first and second rows of unit cells and the plurality of RF input ports to form and control the direction of the radiated RF beam pattern.

Abstract: Cellular array implementations with multiple steerable spotlight beams irradiated from a common aperture are disclosed herein. Such an approach can easily be adapted to suit various geographical population densities and distributions. The array is capable of producing multiple 65-degree cellular coverage beams, which may be used for regular coverage or in MIMO (Multiple Input Multiple Output) mode. The array may also produce multiple steerable beams, or “spotlight” beams. These beams may be relatively narrow and may be steered electronically both in azimuth and elevation directions. By steering the beams in this way, the beams are able to provide cellular services at high-demand “hotspot” regions where high capacity service is required. The spotlight beams may also be used to fill voids or deficiencies caused by regular coverage beams.
