Abstract
Eyewear with a slot ring antenna generating orthogonal E-fields. The slot ring antenna has a first portion including an inner ring and an outer ring generating a first direction E-field, and a second portion having a respective inner ring and the outer ring generating a second direction E-field. The outer ring encompasses the respective inner rings, where a first slot is defined between the respective inner ring and the outer ring. A second slot is encompassed by the respective inner ring, which may be a cutout. The slot ring antenna encompasses eyewear optical assemblies. In one example, the first portion encompasses a first optical assembly, and the second portion encompasses a second optical assembly. A common ground plane of the outer ring may extend proximate a bridge of the eyewear.
