Abstract
An apparatus includes a transceiver circuit, an antenna and a focus array. The transceiver circuit may have a plurality of fed channels configured to generate a plurality of signals. The antenna may have a plurality of antenna arrays configured to generate one or more beams in response to the signals. Each antenna array may (i) have a plurality of subarrays and (ii) be coupled to the fed channels of the transceiver circuit. The focus array may have a plurality of focal zones configured to reflect the beams into a beam zone. Each beam may be steerable by the antenna to one of the focal zones at a time. The focal zones may redirect the beams to a plurality of locations within the beam zone.
