Study on a Magnetron Phased-array Microwave Power Transmission System

Abstract

  As a microwave source, a magnetron has properties of high efficiency, low cost, and light weight. However, the oscillation frequency of the magnetron is unstable. In this paper, we experimentally verified the phase-controlled magnetron utilizing an injection locking method and a PLL method. Using a phase-controlled magnetron as the microwave source, several magnetrons are arrayed to construct a microwave power transmission system. When the magnetrons are working in the same frequency, the phase difference between the magnetrons can control the power transmission direction. Two phase-controlled magnetrons array was demonstrated in the present study.
