Abstract
An antenna is provided for a wearable personal computing device, such as a smartwatch. The antenna integrates with other components of the wearable device, such as a second antenna. For example, the first antenna may be a coupled loop antenna in proximity to a second antenna that may be a monopole antenna, without causing interference between the two antennas. In one example, the first antenna shares a common ground with the second antenna.
Claims21
An antenna, comprising:
- an inner trace, the inner trace having a first end and a second end;
- an outer trace, the outer trace having a first end and a second end, the first end of the outer trace positioned adjacent to the second end of the inner trace, and the second end of the outer trace coupled to a feed for the antenna;
- wherein the inner trace and the outer trace are positioned along a periphery of a wearable device and coupled to a ground;
- and
- wherein the antenna is a coupled loop antenna.
2 more elements
A wearable device, comprising:
- a housing shaped to be worn on a human body, the housing having at least one outer surface and an internal cavity, wherein the at least one outer surface of the housing is shaped to come in contact with the human body;
- a cover configured to enclose the internal cavity of the housing;
- a carrier, the carrier positioned within the internal cavity of the housing along a periphery of the internal cavity;
- a first antenna for a first frequency band, the first antenna being a coupled loop antenna attached to the carrier at a first location, the first antenna comprising:
- an outer trace, the outer trace having a first end and a second end, wherein the first end of the outer trace is coupled to a feed for the first antenna;
- and
- an inner trace, the inner trace having a first end positioned adjacent to the second end of the outer trace.
4 more elements
A system, comprising:
- a first antenna for a first frequency band, the first antenna being a coupled loop antenna having an inner trace and an outer trace, the outer trace having a first end coupled to a feed for the first antenna and the inner trace having a first end positioned adjacent to the second end of the outer trace;
- a second antenna for a second frequency band, the second antenna being a monopole antenna having a first end configured to serve as a feed for the first antenna;
- and
- wherein the first and second antennas are positioned along a periphery of a wearable device and coupled to a common ground.
