First Claim
Patent Images
1. A wireless charging receiver having a wireless charging coil capable of receiving a wireless charging energy using non-contact type magnetic induction and a part for generating a predetermined output power from the wireless charging energy received by the wireless charging coil, the wireless charging receiver comprising:
- a magnetic field insulating sheet;
a NFC coil coupled with the magnetic field insulating sheet;
the wireless charging coil being provided in an inside space surrounded by the NFC coil and spaced apart from the NFC coil in a mutually insulated state;
wherein a first circuit path for receiving a data through the NFC coil and a second circuit path for receiving the wireless charging energy through the wireless charging coil are mutually insulated,wherein the magnetic field insulating sheet, the NFC coil and the wireless charging coil are combined into a set and the set is provided in a portable device, andwherein the NFC coil is inactive while the wireless charging coil is active.
