| 摘要 |
A wireless charging device comprises a transmitter coupled to at least one transmitting antenna and operable to cause the at least one transmitting antenna to emit electromagnetic radiation; a conductive structure adapted to confine the electromagnetic radiation to a charging zone; and a detector for detecting a degree of impedance mismatch between the transmitter and the at least one transmitting antenna. A receiver for use with the wireless charging device and a wireless charging system are also disclosed. |
