Abstract: When the wireless energy transmission system works, it will excite high-frequency electromagnetic fields in the surrounding space, so it has high electromagnetic compatibility index requirements for the wireless energy transmission system. In this paper, the electromagnetic radiation of the transmitting antenna in the wireless microwave energy transmission system to the surrounding environment is modeled and analyzed. The security of electromagnetic radiation in the space around the wireless energy transmitter is studied. The electromagnetic influence of the microwave energy transmitting base station on the surrounding environment is studied. When the transmission power is 500 W, the specific absorption rate of the human head is calculated, and then according to the safety guidelines of international RF exposure, the safe area of electromagnetic exposure of the human body is defined based on theoretical analysis and simulation experiments, the safety of the electromagnetic radiation around the wireless microwave transmitting energy transmitting end is studied. The safe distances of main beam, side lobe and back lobe of base station antenna are determined to be 25 m, 3 m and 2 m, respectively. A reference scheme for wireless microwave energy transmission base station deployment is also given.
