description | This paper presents a design method for wireless power transmission systems in unknown electromagnetic environments. In a wireless power transmission system, several antenna elements are used for power transmitting and one antenna is utilized for power receiving. By measuring the scattering parameters (S-parameters) of the whole system, the power transmission capability of the system can be fully characterized. The maximum possible power transmission efficiency (PTE) can then be determined, and the corresponding excitations for the transmitting antenna elements can be obtained. By designing a feeding network that provides the required excitations to feed the transmitting antenna elements, the optimum power transmission can be achieved without identifying the properties of the unknown electromagnetic environments. Two design examples are presented to demonstrate the proposed method. The measured PTEs are close to the theoretical maximum possible values. |
