Abstract:
Disclosed herein is a wearable device having a horizontally polarized antenna and a vertically polarized antenna to gain the benefit of both types of polarization resulting in optimal signal transmission to and reception by a user's smartphone or mobile device. The wearable device includes a printed circuit board on a first plane along which plane the signal from the horizontally polarized signal will propagate. The printed circuit board includes a conductive ground plane and a trace antenna conductively coupled on one end of the trace to the conductive ground plane between which the horizontally polarized field is generated when the trace antenna is excited. A vertical field enhancer, parallel to the first plane and a distance from the trace antenna, is coupled to the ground plane, such that when the trace antenna is excited, a vertically polarized field is generated between the trace antenna and the vertical field enhancer.
