More Information
Summary:A head-mounted device (10) may include displays (18) that display images to a user while worn. The device (10) may include a conductive frame (58) having a front portion (12-2) and temple portions (12-1). Waveguides (32) may be mounted to the front portion (12-2) for directing image light to eye boxes. Projectors (28) that emit the image light may be coupled to the temple portions (12-1). The frame (58) may include gaps (60) that divide the frame into segments. Two or more of the segments may be fed radio-frequency signals to form one or more antennas (38) in the temple portions (12-1), the front portion (12-2), or between the temple portions and front portion and/or to form isolation elements. A conductive ring (68) may be disposed between the waveguide (32) and a transparent layer and may extend along a lateral periphery of the waveguide (32) to form one or more conductors for one or more antennas and/or isolation elements between two or more antennas.
