Abstract
Apparatuses, methods, and systems for a hinge feed antenna of eyewear, are disclosed. One apparatus includes a front frame, a temple arm, and a hinge rotatably connecting the front frame and the temple arm. For an embodiment, the temple arm includes a circuit assembly including at least a radio. For an embodiment, the front frame includes one or more antennas traces, wherein the hinge conductively connects the circuit assembly to the one or more antenna traces. The apparatus further includes an antenna tuner located between the circuit assembly and the hinge, wherein a rotation position of the temple arm is sensed, wherein the rotation position is dependent on an orientation of the front frame relative to the temple arm; and wherein the antenna tuner includes an impedance tuner for adaptively adjusting an input impedance of the impedance tuner based on the sensed rotation position of temple arm.
