The invention relates to the technical field of
wireless energy transmission, in particular to a superconducting
resonator of a YBCO
film structure and a
wireless energy transmission device. The superconducting
resonator comprises a substrate and a YBCO
microstrip line arranged on the substrate. The YBCO
microstrip line is a complete left spiral strip and specifically comprises a plurality of annular belts which are sequentially arranged from inside to outside; openings are formed in the annular belts and formed in the same straight line; the two ends of each opening are an upper connecting point and a lower connecting point respectively; and in adjacent two annular belts, the lower connecting point of the outer annular belt is connected with the upper connecting point of the inner annularbelt through a connecting strip. The
resonator provided by the invention works in a
liquid nitrogen temperature zone and can be used as a
repeating coil, a transmitting coil or a receiving coil for
wireless energy transmission, the resonator adopts a rectangular spiral
resonance ring and has a compact structure and a
high capacitance effect, so that the
resonance frequency is low, the applicationof a magnetic
resonance wireless energy
transmission system is met, the transmission efficiency is high, the complexity of the
system is low, and the total loss of the
system is small.
