Antenna For Wearable Devices

A wearable electronic device, comprising:

• a housing shaped to be worn on a human body, wherein at least one first surface of the housing is shaped to come in contact with the body and at least one second surface of the housing is shaped to be exposed when worn on the body;
• an input control at the at least one second surface of the housing;
• an antenna at the at least one second surface of the housing, the antenna comprising:
• an outer trace extending partially around the input control, the outer trace having a first end configured to serve as a feed for the antenna;
• an inner trace nested with the outer trace and extending partially around the input control, the inner trace having a second end coupled to ground;
• wherein the first end of the outer trace is positioned opposite the second end of the inner trace.

A wearable electronic device, comprising:

• an input control at the at least one second surface of the housing, the input control including a ground trace;
• and
• an antenna at the at least one second surface of the housing, the antenna comprising:
• a loop trace substantially surrounding the input control, the loop trace including a first end connected to an antenna feed and a second end connected to ground;
• and
• a coupling connecting the loop trace to the ground trace.
