Antenna technology for beamed space-power
Based on present technology, the efficient transfer of RF power in space is feasible. However, many parameters must be taken into consideration when designing the system and the interrelationships of these parameters must also be considered. Once the distance between the orbiting spacecraft is specified and the transmit frequency is chosen, then the maximum size for the transmit and receive antennas is fixed (i.e., Rayleigh Range). Once the level of transmit power and trasmit time is specified, then the minimum number of spacecraft batteries is determined. High power RF transmission allows the satellite designer another option in the design of spacecraft power systems.
