Abstract
A wireless charging transmission apparatus by using 3D polyhedral magnetic resonance based on multi-antenna switching includes a magnetic resonance wireless energy transmitting module, a plurality of magnetic resonance transmitting antennas, a plurality of receiving antennas, and a magnetic resonance wireless energy receiving module that are connected in sequence. The magnetic resonance wireless energy transmitting module is configured to convert DC power into RF energy and control an operation mode. The magnetic resonance transmitting antennas are configured to convert the RF energy into a spatially distributed reactive field. The receiving antennas are configured to convert the reactive field into the RF energy. The magnetic resonance wireless energy receiving module is configured to convert the RF energy into DC power and charge or power a load. When one of the transmitting antennas is used as a main transmitting antenna, the rest transmitting antennas are used as relay coupling antennas.
