Abstract
A communication system can include a support structure, a receiving phased array antenna, and a transmitting phased array antenna that is physically superimposed with the receiving phased array antenna on the support structure. The receiving phased array antenna can include a plurality of receiving antennas and/or transmitting/receiving antennas, and the transmitting phased array antenna can include a plurality of transmitting/receiving antennas and/or transmitting antennas, with at least a subset of transmitting/receiving antennas shared between the two phased array antennas. Appropriate spacing between the antennas of the receiving and transmitting phased array antennas can be achieved by overlaying the transmitting phased array antenna with a rotational offset compared to the receiving phased array antenna, and the different spacing of the antennas in the receiving phased array antenna and the transmitting phased array antenna permits the use of each array in different frequency bands.
