Abstract

Disclosed is an antenna assembly including a substrate, and a wireless charge antenna pattern on the substrate. The wireless charge antenna pattern has a sectional surface including a plurality of inner angles in which two inner angles are different from each other. The antenna assembly includes a wireless communication antenna pattern formed on the substrate and provided at an outside of the wireless charge antenna pattern. The wireless communication antenna pattern has a plurality of inner angles at a sectional surface thereof, and a plurality of angle values of the inner angles provided at the sectional surface of the wireless communication antenna pattern correspond to a plurality of angle values of the inner angles provided at the sectional surface of the wireless charge antenna pattern, respectively.
