Abstract

The invention discloses a high-efficiency dual-band planar wireless energy transmission system, which comprises a transmitting end and a receiving end, wherein both the transmitting end and the receiving end have the same circuit structures; each circuit structure comprises a front microstrip structure, a middle dielectric substrate and a back microstrip structure; the front microstrip structure is printed on the upper surface of the middle dielectric substrate; the back microstrip structure is printed on the lower surface of the middle dielectric substrate; the front microstrip structure comprises a front feed coil, a first resonator and a second resonator; and the back microstrip structure comprises an external port connected with the front feed coil. One feed coil is used for feeding two resonators of different bands to generate a dual-band high-efficiency wireless energy transmission system.

Description

technical field [0001] The invention relates to a wireless energy transmission system, in particular to a high-efficiency dual-frequency planar wireless energy transmission system. Background technique [0002] With the increasing demand for contactless power supply, wireless energy transfer technology continues to develop. In recent years, people have begun to conduct in-depth research on this technology. The wireless energy transmission technology using magnetic coupling resonance has gained a lot of attention. This technology has been widely used in electric vehicles and in the power supply of micro-implanted medical instruments. In recent years, more and more scholars have participated in the research of multi-frequency wireless energy transfer systems. Compared with single-frequency wireless energy transfer systems, multi-frequency wireless energy transfer systems can provide more channels to transmit energy or information. However, how to generate multi-frequency tr...
