  • Wireless charging module coated with magnetic material on surface of coil
    Patent number: 11770021
    Abstract: Disclosed is a coil module that receives or transmits electric power or signals wireless by using an electromagnetic field, the coil module including a board, a coil provided on at least one surface of the board to be rotated in one direction, and a magnetic part covering at least a portion of the coil while directly contacting a surface of the coil, and that acts as an electromagnetic booster that enhances an intensity of the electromagnetic field generated on the surface of the coil, and the magnetic part decrease, among a skin effect and a proximity effect of an eddy current generated in the coil, the proximity effect by isolating electric power in a gap of the coil that is rotated in the one direction.

  • METHOD OF MANUFACTURING WIRELESS CHARGING COIL MODULE COATED WITH MAGNETIC MATERIAL ON SURFACE OF COIL
    Publication number: 20230116340
    Abstract: Disclosed is a method of manufacturing a coil module that receives or transmits electric power or signals wireless by using an electromagnetic field. The method includes preparing a substrate, forming a coil on the substrate, and forming a magnetic part covering at least a portion of the coil while directly contacting a surface of the coil, and that acts as an electromagnetic booster that enhances an intensity of the electromagnetic field generated on the surface of the coil, and the magnetic part is formed through at least one of electroless plating, electro-plating, deposition, and printing.
