Wearable device antennas

A watch, comprising:

• a body having an external band;
• at least one conductive element disposed on the external band and configured to form at least a portion of a primary radiating element;
• a first coupling element galvanically coupled to the primary radiating element, the first coupling element having a first length parallel to at least a portion of the primary radiating element;
• a second coupling element galvanically coupled to the primary radiating element, the second coupling element having a second length different that the first length parallel to at least a portion of the primary radiating element;
• a secondary radiating element configured to couple with the first and second coupling elements;
• and
• a feed line disposed to supply a radiofrequency signal to the secondary radiating element, wherein the primary radiating element is configured to radiate in a first frequency range when the secondary radiating element receives a first radiofrequency signal in the first frequency range from the feed line and couples the first radiofrequency signal to the primary radiating element, and the secondary radiating element is configured to radiate in a second frequency range when receiving a second radiofrequency signal in the second frequency range.
