Wearable electronic device including biometric sensor and wireless charging module

An electronic device comprising:

• a housing including a first surface oriented in a first direction, and a second surface oriented in a second direction opposite the first direction;
• a display disposed such that at least a portion thereof is viewable through the first surface;
• a main circuit board disposed in a space between the first surface and the second surface;
• a sensor module disposed to be exposed to at least a partial area of the second surface;
• and
• a battery disposed in a space between the first surface and the main circuit board,
• wherein the sensor module includes:
• a circuit board having a first surface facing the second surface of the housing and second surface facing the first surface of the housing;
• a biometric sensor disposed in a first area on the first surface of the circuit board;
• an antenna for wirelessly charging the battery, the antenna comprising a conductive line disposed in a second area of the circuit board and wound for at least one turn to surround at least a portion of the biometric sensor when viewed from above the first surface of the circuit board;
• a plurality of electrode pads disposed in a third area of the secondsurface of the circuit board;
• an electronic component comprising electronic circuitry disposed in the third area and electrically connected to at least one of the plurality of electrode pads;
• and
• a shield disposed in a fourth area of the second surface of the circuit board, and
• wherein the circuit board includes a plurality of stacked sub circuit boards, and the antenna comprising the conductive line disposed on at least one of the plurality of stacked sub circuit boards, and
• wherein the conductive line is wound by at least one turn around edges of at least one of the plurality of stacked sub circuit boards.
