Abstract

The invention discloses a wireless charging receiving antenna structure, comprising: a substrate; an M-turn coil disposed on the substrate; an isolation region disposed between the two adjacent coils;a coil groove disposed on the outermost N-turn of the coil, wherein N<M; a first electrode electrically connected onto a first end of the coil; and a second electrode electrically connected onto a second end of the coil.

Description

Technical field [0001] The invention relates to the technical field of wireless charging, in particular to a high-efficiency wireless charging receiving antenna. Background technique [0002] Wireless Charging Technology (Wireless Charging Technology) refers to a technology that realizes non-contact power transmission via air medium through electromagnetic induction, electromagnetic resonance, etc., not through wires. Compared with traditional charging methods, wireless charging technology does not require wiring and charging terminals, which is more convenient. With the development of power electronics, power conversion and control technology, wireless charging technology has gradually achieved breakthroughs in conversion rate and low radiation. At present, wireless charging has been implemented in some home appliances such as electric toothbrushes, electric shavers, cordless phones, etc. Practical, now its scope of application has expanded to the field of smart phones, and in ...
