Abstract: A wireless power transmission system is provided. The wireless power transmission system includes a transmitting antenna and a receiving antenna. The transmitting antenna is coupled to a power source device, and the transmitting antenna is a Yagi-Uda antenna. The transmitting antenna receives a first power signal provided by the power source device and transmits a power radiation signal toward a first direction. The receiving antenna is coupled to a rectifier, the rectifier is coupled to a power receiver, and the receiving antenna is a Yagi-Uda antenna. The receiving antenna has a predetermined distance from the transmitting antenna. The receiving antenna receives the power radiation signal and converts the power radiation signal into a second power signal. The rectifier converts the second power signal into a third power signal and transmits the third power signal to the power receiver.
