High efficient beam forming with high efficient phased array for microwave power transmission

In this paper, we show the system of a Space Solar Power Satellite/Station (SPS) with a huge phased array whose number of the antenna elements is over 2 billions and whose size is over 2km for 5.8GHz microwave in order to transmit a wireless power via microwave to the ground. We concentrate over 90% of the microwave power for the wireless power transmission, which means the accuracy of the microwave beam is below 0.0001 degree in condition that the shape of the huge phased array can not stabilized in space. For the high accurate beam forming and target detecting, we choose the new method called PAC (Position and Angle Correction) which was proposed for the panel-structure phased array of the SPS. We use a pilot signal from the target and information of the panel connection in the PAC method. We show simulation results of the PAC beam forming method and propose the revised method to increase the beam efficiency in this paper.
