Abstract
An eyewear device has an antenna system having at least one element which contributes to wireless signal transmission, and which is thermally connected to a heat-generating electronic component of the eyewear device to serve as a heat sink for the electronic component. A driven antenna element and/or a plurality of PCB extenders electrically connected to a PCB ground plane can thus be employed for both signal transmission and heat management.
Claims17
An eyewear device comprising:
- an eyewear body comprising:
- an eyewear frame defining one or more optical element holders for holding respective optical elements within view of a user when the eyewear device is worn;
- and
- a pair of temples connected to the eyewear frame for supporting the eyewear frame in position during wear;
- a driven antenna element incorporated in the eyewear frame;
- a printed circuit board (PCB) that is housed by the device body and that carries on-board communication electronics coupled to the driven antenna element to communicate wireless signals via the driven antenna element, the PCB defining a PCB ground plane coupled to the communication electronics for co-operation with the driven antenna element in signal communication;
- and
- a PCB extender comprising a conductor electrically connected to the PCB ground plane and projecting from the PCB for co-operation with the driven antenna element in signal communication, the PCB extender extending along an associated one of the pair of temples.
