The SPS (Space Solar Power Satellite/Station) will be clean base-load power station in space. It will be hugest space system and we need high efficient, huge, high accurate, light weight and inexpensive phased array for the SPS in order to transmit energy generated in space from space to ground. We have proposed and developed a phase controlled magnetron (PCM) with injection locking and PLL technique for the high efficient, light weight and inexpensive phased array. It has still weak points; (1) it contains approximately 10% power loss at circulator for injection locking, (2) we need phase shifter in each PCMs for the phased array. In order to solve the weak points, we propose a magnetron phased array with mutual injection locking. For the magnetron phased array, we only use two PCMs with phase shifters and the other components are self-oscillated and mutual injection locked magnetrons. In this paper, we propose new formula for the magnetron phased array with mutual injection locking. We also show experimental results of beam direction control with the magnetron phased array with mutual injection locking.
