RETRO DIRECTIVE ARRAY ANTENNA DEVICE AND SPACE PHOTOVOLTAIC POWER GENERATION SYSTEM USING SAME

摘要

PROBLEM TO BE SOLVED: To obtain a small size/light weight retro directive array antenna device which does not need a calculating process without coupling a pilot reception wave and a transmission wave.

SOLUTION: The retro directive array antenna device uses a pilot signal sent from the reception antenna installing position being AM modulated light. The retro directive array antenna device includes an array antenna having a plurality of transmission antenna elements, light receiving means respectively provided one by one correspondingly near the plurality of the transmission antennas to receive the pilot signal and to convert it into an electric signal, and a phase conjugate circuit for radiating the radio wave of the phase inverted from the phase of the electrical signal from the plurality of the transmission antenna elements. The main beam of the array antenna is directed in the incoming direction of the pilot signal.
