Phase Synchronization Principle in 5.8 GHz Magnetron Phased Array

This paper analyzes the influence parameters of the phase control of the magnetron in detail and proposes a method to realize the frequency locking and phase synchronization of the magnetron. The noise-inhibition of the magnetron has made great progress in previous research, and the power and phase can be simultaneously controlled. Based on this principle, the phases of multiple magnetrons are synchronized and successfully applied to phased arrays. A $2 \times 2$ 5.8GHz magnetron phased array was constructed with a maximum output power of 1680W and the beam-forming experiment of the magnetron phased array was demonstrated for wireless power transfer.
