Abstract

A base including a magnetically resonant antenna therein for relaying energy to a portable device.

Claims

exact text as granted — not AI-modified
1 . An apparatus for wireles sly charging an electronic device, the apparatus comprising:
 a holder having at least one surface that is shaped to contact at least one outer surface of the electronic device, the portable electronic device including a wireless power receive element coupled to a load; and   an antenna located within the holder, the antenna having an inductive-capacitive value that is tuned to a frequency and configured to receive power from a transmitter via a wireless field, and further configured to focus wireles sly received power to a power level sufficient to charge or power the load.   
     
     
         2 . The apparatus of  claim 1 , wherein the wireless field comprises a magnetically coupled resonance field. 
     
     
         3 . The apparatus of  claim 2 , wherein focusing the wirelessly received power improves an efficiency of the magnetically couple resonance field. 
     
     
         4 . The apparatus of  claim 2 , wherein focusing the wireless received power increases a field density of the magnetically coupled resonance field. 
     
     
         5 . The apparatus of  claim 1 , wherein the antenna further comprises an inductive loop coil and a capacitor, the inductive loop in series with the capacitor. 
     
     
         6 . The apparatus of  claim 5 , wherein a Q value of the coil and the capacitor is substantially between 500 and 1000. 
     
     
         7 . The apparatus of  claim 5 , wherein the coil and the capacitor are tuned to be substantially resonant with the wireless field. 
     
     
         8 . The apparatus of  claim 1 , wherein the antenna is integrated into a base of the holder. 
     
     
         9 . The apparatus of  claim 8 , wherein the perimeter of the holder is substantially circular. 
     
     
         10 . The apparatus of  claim 8 , wherein inner surfaces of the holder are sized to mount a phone in the holder's base. 
     
     
         11 . A method of wirelessly charging an electronic device, the method comprising:
 receiving power from a transmitter via a wireless field by an antenna located within a holder, the holder having at least one surface that is shaped to contact at least one outer surface of the electronic device, the portable electronic device including a wireless power receive element coupled to a load; and   focusing wirelessly received power to a power level sufficient to charge or power the load.   
     
     
         12 . The method of  claim 11 , wherein receiving the power comprises receiving power from the transmitter via a magnetically coupled resonance field. 
     
     
         13 . The method of  claim 12 , wherein focusing the wirelessly received power comprises focusing the wirelessly received power to improve an efficiency of the magnetically couple resonance field. 
     
     
         14 . The method of  claim 12 , wherein focusing the wirelessly received power comprises focusing the wirelessly received power to increase a field density of the magnetically coupled resonance field. 
     
     
         15 . The method of  claim 11 , wherein receiving the power comprises receiving the power by the antenna further comprising an inductive loop coil and a capacitor, the inductive loop in series with the capacitor, and the coil and the capacitor tuned to be substantially resonant with the wireless field. 
     
     
         16 . An apparatus for wirelessly charging an electronic device, the apparatus comprising:
 means for receiving power from a transmitter via a wireless field by an antenna located within a holder, the holder having at least one surface that is shaped to contact at least one outer surface of the electronic device, the portable electronic device including a wireless power receive element coupled to a load; and   means for focusing wirelessly received power to a power level sufficient to charge or power the load.   
     
     
         17 . The apparatus of  claim 16 , wherein the wireless field comprises a magnetically coupled resonance field. 
     
     
         18 . The apparatus of  claim 16 , wherein the antenna further comprises an inductive loop coil and a capacitor, the inductive loop in series with the capacitor. 
     
     
         19 . The apparatus of  claim 18 , wherein the coil and the capacitor are tuned to be substantially resonant with the wireless field. 
     
     
         20 . The apparatus of  claim 16 , wherein the antenna is integrated into a base of the holder.
