1. A wireless power receiver comprising:
- a resonator configured to emit an electromagnetic field;
a blocker configured to surround a portion of an exterior of the resonator; and
a spacer disposed between the resonator and the blocker,wherein the resonator is in a loop shape and the blocker surrounds an outside of the resonator, the blocker has a cross section corresponding to a cross section of the resonator, and at least one side of the blocker is open and directs to an inner center of the resonator in the loop shape, andwherein the spacer comprises a supporting medium configured to maintain a distance between the resonator and the blocker, and the supporting medium is a screw contacting the resonator at a first end and passing through the blocker at a second end.
