Abstract The efficiency is one of the key parameters in a wireless power transmission system. This paper analyzes the efficiency of a long-distance wireless power transmission system based on a microwave reflector antenna, coming up with a general expression consisting of generator efficiency, transmit efficiency and receive efficiency. The transmit efficiency is then factorized into a few necessary sub-efficiencies. In addition, the Eleven Feed antenna is introduced, which is based on log-periodic folded dipole array and suitable for microwave reflector antenna system.
