Hybrid antenna system for wearable devices

A wearable device comprising:

• a body;
• onboard electronics carried by the body;
• and
• an antenna system connected to the onboard electronics and housed by the body to provide wireless connectivity to the onboard electronics, the antenna system comprising:
• a loop conductor configured to provide loop antenna functionality;
• a non-loop conductor configured to provide dipole antenna functionality;
• and
• a signal feed mechanism connected in common to the loop conductor and the non-loop conductor at a signal feed point to transceive electrical signals simultaneously through both the loop conductor and the non-loop conductor,
• wherein the non-loop conductor is provided by a dipole conductor that comprises two elongate arms connected at adjacent ends thereof to the signal feed point, the feed point being offset from a lengthwise center of the dipole conductor, such that the dipole conductor is offset-fed and comprises a shorter arm and a longer arm;
• and
• wherein the longer arm of the dipole conductor has, for at least part of its length, an increased width relative to the shorter arm of the dipole conductor, the increased width of the longer arm being provided by a loop-shaped portion of the dipole conductor.

An eyewear device comprising:

• an eyewear body configured for supporting one or more lenses within view of a user;
• onboard electronics incorporated in the eyewear body;
• and
• an antenna system housed in the eyewear body and connected to the onboard electronics to provide wireless connectivity to the onboard electronics, the antenna system comprising:
• a loop conductor configured to provide loop antenna functionality;
• a non-loop conductor configured to provide dipole antenna functionality;
• and
• a signal feed mechanism connected in common to the loop conductor and the non-loop conductor at a signal feed point to transceive electrical signals simultaneously through both the loop conductor and the non-loop conductor,
• wherein the non-loop conductor is provided by a dipole conductor that comprises two elongate arms connected at adjacent ends thereof to the signal feed point, the feed point being offset from a lengthwise center of the dipole conductor, such that the dipole conductor is offset-fed and comprises a shorter arm and a longer arm;
• and
• wherein the longer arm of the dipole conductor has, for at least part of its length, an increased width relative to the shorter arm of the dipole conductor, the increased width of the longer arm being provided by a loop-shaped portion of the dipole conductor.
