AbstractABSTRACT: Future SATCOM payload antennas need to provide much greater spot beam control flexibility. Currently deployed systems utilize phased array fed dishes limiting the number of spot beams and gain since earth coverage is accomplished by limiting the number of beamwidths scanned. The solution proposed is a direct illumination phased array that is scaleable for very high gain. Greater than 30 simultaneous beams are supported without substantially increasing the integration complexity of the beamforming network over a single beam phased array. The proposed approach leverages commercially available components but proposes to integrate more devices into a single package for greater function density and board area reduction. The proposed Phase I program will validate through simulation and test the fundamental building block for this advanced multi-beam phased array for future Ka-band SATCOM payload antennas. BENEFIT: FIRST RF is proposing a scalable, modular approach to multibeam phased arrays that does not require the cost, size, and complexity of multiple RF manifolds. This leap ahead in phased array technology will be advantageous in all applications for directive array antennas. Applications that will benefit from multiple beams include high data-rate line of sight communications for mobile military forces (ground, air, and sea) where multiple beams can increase frequency re-use and network capacity and multi-beam radars. Multi-function wideband arrays are also being developed to simultaneously support communications, electronic support, and electronic attack functions. A lightweight, cost-effective means for providing multiple beams will significantly increase the capability of those systems and increase the flexibility of platform integration. Commercial MIMO and"smart antenna"communications networks will benefit from a low cost multi-beam array by increasing communications capacity and range in complex environments.
