This figure shows the block diagram of the MPT system. The MPT system consists of a wireless power transmitter and a wireless power receiver.
In the MPT system, the overall power transmission efficiency is greatly affected by the distance-dependent attenuation, impedance matching, and RF-DC conversion efficiency.
Therefore, an effective impedance matching circuit configuration and a high-efficiency RF-DC rectifier should be used in the power receiver.
In addition, in the power transceiver, it is necessary to overcome the decrease in power transmission efficiency due to path loss by increasing the antenna gain of the transmitter and the receiver by using a plurality of antennas.
