Abstract : There is much current interest in the use of phased array antennas for military satellite communications terminals. These antennas present definite advantages over conventional dish antennas, such as electronic steering capability, conformal surface potential, and graceful degradation. In view of the potential of phased arrays, CRAD initiated an R&D project, as part of the Military Information and Technology Infrastructure (MITI) thrust, to provide advice on issues such as performance benefits, potential technical improvements, implementation issues, and potential market niche areas. In this report, this process is initiated by generating a set of specifications for the development of such phased array antennas. Five types of terminals are analyzed, namely: EHF manpack, EHF airborne, EHF land transportable, multi-band vehicle mounted, and multi-band shipboard. For the five strawman applications, performance specifications such as EIRP, G/T, etc. are provided.
