N2 - Long-range wireless power transfer technologies via an electromagnetic (EM) can be applied to various research area such as supplying power to Internet of Things (IoT) devices. One of the most primary challenge needs to be solved in radio frequency (RF) WPT system is high attenuation of the EM wave, besides, the higher frequency it has the much more losses it gets. In this paper, we provide an experimental study on the multiantenna to multi-antenna EM wave wireless power transfer (WPT) system. For maximizing the transfer efficiency, we investigate a beam focusing technology based on singular value decomposition method with measured S-parameter values. We have built a prototype multi-antenna to multi-antenna WPT system testbed for 5.8GHz frequency consists of phased array transmit and receive circuits and circularly polarized (CP) antenna. Based on the experiment results, we show that the capability of the turning RF WPT concept into reality.
