Electronic device including non-contact charging module and near field communication antenna

Abstract

An electronic device having a communication capability is provided. The electronic device includes a housing having a generally rectangular shape in a plan view of the housing, and a non-contact charging module included in the housing. The non-contact charging module includes (i) a wireless charging coil having a substantially planar shape and formed of a wound electrical wire, and (ii) a magnetic sheet that overlaps with the wireless charging coil in the plan view of the housing. The electronic device further includes a Near Field Communication (NFC) antenna included in the housing and including an NFC coil formed of a wound electrical wire, and a guide having a generally rectangular outer shape in the plan view of the housing. The guide has a hole and the wireless charging coil is arranged in the hole of the guide.

         2 . The electronic device of  claim 1 , wherein the hole is shaped to generally follow an outer shape of the wireless charging coil. 
     
     
         3 . The electronic device of  claim 2 , wherein the outer shape of the wireless charging coil has a generally circular shape, and the hole is shaped to follow the generally circular shape of the wireless charging coil. 
     
     
         4 . The electronic device of  claim 1 , wherein the hole has a generally circular shape. 
     
     
         5 . The electronic device of  claim 1 , wherein the NFC antenna is arranged adjacent to and outside of the wireless charging coil. 
     
     
         6 . The electronic device of  claim 1 , wherein the wireless charging coil has a first resonant frequency and the NFC coil has a second resonant frequency different from the first resonant frequency. 
     
     
         7 . The electronic device of  claim 6 , wherein the first resonant frequency of the wireless charging coil is lower than the second resonant frequency of the NFC coil. 
     
     
         8 . The electronic device of  claim 1 , wherein a number of windings included in the wireless charging coil is greater than a number of windings included in the NFC coil. 
     
     
         9 . The electronic device of  claim 1 , wherein a power transfer frequency of the wireless charging coil is different from a communication frequency of the NFC coil. 
     
     
         10 . The electronic device of  claim 1 , wherein the NFC coil is formed of the wound electrical wire and including a substrate. 
     
     
         11 . The electronic device of  claim 1 , wherein at least a portion of the NFC coil is disposed outside of the sheet. 
     
     
         12 . The electronic device of  claim 1 , wherein at least a portion of the NFC coil is disposed on a second sheet different from the sheet of the non-contact charging module. 
     
     
         13 . The electronic device of  claim 1 , wherein the NFC coil is configured to perform communication by electromagnetic induction.
