Abstract

An antenna structure is provided that improves performance of a Near Field Communication antenna by constructing a pattern for NFC in an inner center region of a pattern for a wireless charging pad. The structure includes a Printed Circuit Board including a first and a second substrate layer, where the first substrate layer includes a first and a second non-conductive area, one first conductive wire constructed in a shape surrounding the first non-conductive area, one second conductive wire constructed in a shape surrounding the second non-conductive area, and a first antenna corresponding to a first frequency band. The second substrate layer includes a third non-conductive area, a third wire surrounding the third non-conductive area, and connection wires electrically coupling the first and the second conductive wire forming a second winding. The first winding and the second winding are a second antenna corresponding to a second frequency band.
