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.
Claims20
An apparatus comprising:
- a transceiver circuit comprising a plurality of fed channels configured to generate a plurality of signals;
- an antenna comprising a plurality of antenna arrays configured to generate a plurality of beams in response to said signals, wherein each of said antenna arrays (i) comprises a plurality of subarrays and (ii) is coupled to said fed channels of said transceiver circuit;
- and
- a focus array comprising a plurality of focal zones configured to reflect said beams into a beam zone, wherein (i) each of said beams is steerable by said antenna to one of said focal zones at a time, (ii) said focal zones redirect said beams to a plurality of locations within said beam zone and (iii) each of said focal zones is associated with a respective one of said locations within said beam zone.
A system comprising:
- a plurality of transceiver antenna array modules each comprising a transceiver circuit and an antenna, wherein (i) each of said transceiver circuits comprises a plurality of fed channels, (ii) each of said antenna is coupled to said fed channels of a corresponding one of said transceiver circuits, (iii) each of said antenna comprises a plurality of subarrays and (iv) each of said antenna is configured to generate a plurality of beams;
- and
- a plurality of focus arrays each comprising a plurality of focal zones configured to reflect said beams into a beam zone, wherein (i) each of said beams is steerable by said antennas to one of said focal zones at a time, (ii) said focal zones redirect said beams to a plurality of locations within said beam zone and (iii) each of said focal zones is associated with a respective one of said locations within said beam zone.
