Multi-antenna magnetic-resonance super-narrowband wireless energy and signal co-frequency transmission system

The invention provides a multi-antenna magnetic-resonance super-narrowband wireless energy and signal co-frequency transmission system which comprises a driving module, an antenna module and a load module. The driving module comprises a power supply, a frequency generator, a controller, a modulator, a power amplifier, an impedance match unit and a demodulator; the antenna module comprises coils and a tuning capacitor; and the load module comprises an impedance match device, a rectifier, a demodulator, a modulator and an application circuit. The driving module emits energy and signal to a free space in a coordinated manner, and the energy and signal are transmitted wirelessly by the antenna module and then received by the load module. In the driving module and the load module, the modulators and demodulators employ the super-narrowband technology, namely Very Minimum Chirp Keying (VMCK), to overcome the defect that the communication bandwidth of the wireless energy transmission system based on magnetic resonance is relatively low. The multi-antenna magnetic-resonance super-narrowband wireless energy and signal co-frequency transmission system includes wireless transmission based on magnetic resonance, has the advantages including high transmission efficiency, long transmission distance and capability of bidirectional communication, is not afraid of obstacles and is flexible to realize.
