Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A wearable device, comprising:
an outer housing including a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a side surface surrounding a space between the first surface and the second surface and including a metal frame formed thereon, the metal frame not being partitioned and having a closed loop shape;
a display disposed in the space and being at least partially visible via the first surface of the outer housing;
a printed circuit board (PCB) disposed between the second surface and the display and including a ground area; and
a communication circuit disposed at the PCB,
wherein the metal frame is:
electrically connected with the communication circuit at a first point of the metal frame,
electrically connected with the ground area at a second point of the metal frame, and
selectively connected with the ground area at a third point of the metal frame via an impedance tuner including an impedance matching component,

wherein a first distance between the first point and the third point is longer than a second distance between the first point and the second point, and
wherein the communication circuit is configured to:
transmit and/or recieve a signal in a first frequency band by a first signal path established if the third point is directly connected to the ground area via the impedance tuner without the impedance matching component, and
transmit and/or receive a signal in a second frequency band by a second signal path established if the third point is indirectly connected to the ground area via the impedance tuner with the impedance matching component.
