`
`
`
`
`
`A wireless powerreceiver can include a magnetic substrate
`
`
`
`
`
`
`
`and a coil configured to wirelessly receive power. The coil
`
`
`
`
`
`
`
`can be formed as a conductive layer on the magnetic
`
`
`
`
`
`substrate. A connecting unit can be disposed in a receiving
`
`
`
`
`
`
`space of the magnetic substrate and can be connected to the
`coil unit.

`
`
`
`
`
`connecting unit to be connected to an external circuit to a

`
`
`
`
`
`
`
`
`disposing the coil unit on a top surface of the magnetic
`
`
`
`
`
`
`
`substrate. According to one embodiment, the high power
`
`
`
`
`
`
`transmission efficiency can be ensured and communication
`
`
`
`
`
`
`
`with external devices can be enabled by directly disposing
`the coil unit andthe near field communication antenna on the
`
`
`
`
`
`
`
`
`
`
`
`
`
`top surtace of the magnetic substrate.
`
`
`
`
`
`
`According to one embodiment, the manufacturing process
`
`
`
`
`
`
`
`
`‘or the wireless powerreceiver can be simplified bydirectly
`
`
`
`
`
`
`
`
`
`disposing the coil unit on the magnetic substrate only
`
`
`
`
`
`through laminating and etching processes.
`
`
`
`
`
`
`
`According to one embodiment, the thickness of the wire-
`
`
`
`
`
`
`
`less powerreceiver can be remarkably reduced by forming
`
`
`
`
`
`
`
`the conductive pattern inside the magnetic substrate.
`
`
`
`
`
`
`
`According to one embodiment, the high power transmis-
`
`
`
`
`
`
`
`sion efficiency can be ensured by forming the conductive
`
`
`
`
`
`
`
`pattern inside the magnetic substrate and the communication
`
`
`
`
`
`
`
`
`
`with external devices can be enabled by using the nearfield
`communication antenna.
`
`
`
`
`
`
`
`
`According to one embodiment,
`the connecting unit
`is
`
`
`
`
`
`
`
`disposed in the receiving space of the magnetic substrate so
`
`
`
`
`
`
`
`
`
`
`that the thickness of the wireless power receiver can be
`
`
`
`
`
`
`
`
`remarkably reduced as much as the thickness of the con-
`
`
`necling, unit.
`
`
`
`
`
`
`According to one embodiment, a tape substrate is used as
`
`
`
`
`
`
`
`
`
`
`the connecting unit so that the overall size of the wireless
`
`
`
`
`powerreceiver can be reduced.
`
`
`
`
`
`
`
`According to one embodiment,a lead frame is used as the
`
`
`
`
`
`
`
`
`
`connecting unit, so the wiring layer included in the connect-
`
`
`
`
`
`
`
`
`
`ing unit can be protected fromthe heat, external moisture or
`
`
`
`
`
`
`
`impact and the mass production can berealized.
`
`
`
`
`
`
`
`According to one embodiment, the magneticfield directed
`
`
`
`
`
`
`
`
`
`
`
`to the outside can be changed into the coil unit due to the
`
`
`
`
`
`
`
`
`conductive pattern formed in the magnetic substrate, so the
`
`
`
`
`
`
`
`
`powertransmission efficiency can be improved, at the same
`
`
`
`
`
`
`
`
`
`time, the amount of the magnetic field leaked to the outside
`
`
`
`
`
`
`
`
`can be reducedso that the bad influence of the magneticfield
`
`
`
`
`
`
`exerted to the human body can be diminished.
`
`
`
`
`
`
`
`
`The embodimentrelates to a wireless power receiver and
`
`
`
`
`
`
`
`
`
`a method of manufacturing the same. In more particular, the
`
`
`
`
`
`
`
`
`embodiment relates to a wireless power receiver used for
`
`
`
`
`
`
`
`wireless power transmission or an antenna to reduce a
`
`
`
`
`
`
`
`
`thickness of the wireless powerreceiver and to simplify the
`
`
`
`
`
`
`manufacturing process thereof and a method of manufac-
`
`
`
`turing the same.
`
`
`
`
`
`
`
`Awireless powertransmission or a wireless energy trans-
`
`
`
`
`
`
`fer refers to a technology of wirelessly transferring electric
`
`
`
`
`
`
`
`
`
`energy to desired devices. In the 1800’s, an electric motor or
`
`
`
`
`
`
`
`a transformer employing the principle of electromagnetic
`
`
`
`
`
`
`
`
`induction has been extensively used and then a method of
`
`
`
`
`
`transmitting electrical energy byirradiating electromagnetic
`
`
`
`
`
`
`
`
`waves, such as radio wavesorlasers, has been suggested.
`
`
`
`
`
`
`Actually, electrical toothbrushes or electrical razors, which
`
`
`
`
`
`
`
`
`
`are frequently used in daily life, are charged based on the
`
`
`
`
`
`principle of electromagnetic induction. The electromagnetic
`
`
`
`
`
`
`
`
`
`induction refers to the generation of an electric current
`
`
`
`
`
`
`
`
`through induction of a voltage when a magnetic field is
`
`
`
`
`
`
`changed around a conductor. The elecwomagnetic induction
`
`
`
`
`
`
`
`scheme has been successfully commercialized for electronic
`
`
`
`
`
`
`
`appliances having small sizes, but represents a problem in
`
`
`
`
`
`
`
`that the transmission distance of poweris too short.
`
`
`
`
`
`
`
`Besides the electromagnetic induction scheme, the long-
`
`
`
`
`
`
`
`
`distance transmission using the resonance and the short-
`
`
`
`
`
`
`
`
`wavelength radio frequency has been suggested as the
`
`
`
`
`wireless energy transfer scheme.
`
`
`
`
`
`
`
`However, in general, a wireless powerreceiver disposed
`
`
`
`
`
`
`
`
`in a terminal has a thick thickness and the manufacturing
`
`
`
`process thereof is complicated.
