Wearable electronic device comprising antenna

A wearable electronic device comprising:

• a housing including a first case and a second case combined with the first case;
• a substrate disposed in an internal space of the housing;
• an antenna carrier disposed between the substrate and the first case in the internal space;
• a first conductive pattern disposed on the antenna carrier;
• at least one second conductive pattern disposed on the antenna carrier;
• a wireless communication circuit disposed on the substrate and configured to transmit and/or receive a radio signal in a designated frequency band through the first conductive pattern;
• and
• a touch sensor disposed on the substrate and configured to detect a touch on the first case through the first conductive pattern,
• wherein the first conductive pattern is formed in an open loop shape, and the at least one second conductive pattern is disposed within a space defined by the open loop shape, and
• wherein the at least one second conductive pattern is disposed at a position capable of being capacitively coupled with the first conductive pattern upon the touch.
