Wearable device comprising printed circuit board including conductive pattern, and electronic device

An electronic device comprising:

• a housing including:
• a first plate,
• a second plate facing the first plate, and
• a lateral frame, disposed between the first plate and the second plate, including a conductive portion;
• a printed circuit board (PCB), disposed in the housing, including a conductive pattern;
• a key button inserted into an opening formed in the lateral frame;
• a flexible PCB (FPCB), contacted with a conductive portion connected to the conductive pattern of the PCB and a portion of the key button, including signal line configured to obtain an input signal through movement of the key button;
• a bracket, electrically connected to a ground portion of the PCB, disposed between the PCB and the first plate;
• an antenna using the lateral frame, the conductive pattern, and the conductive portion as a radiator;
• and
• wireless communication circuitry electrically connected to the antenna,
• wherein the conductive portion is electrically connected to the conductive pattern.
