Footprint Sharing Sparse Arrays for 20 and 30 GHz
Paper i proceeding, 2016
Communication via satellites primarily uses reflector antennas on the spacecraft. In future systems, direct radiating arrays can be an alternative, but in order to reduce the number of elements, sparse arrays are considered. Furthermore, it would be advantageous if the transmit (TX) and receive (RX) arrays could be colocated within the same footprint.
