    摘要: Eyewear with a slot ring antenna generating E-fields that are orthogonal to each other at a frequency. The slot ring antenna has a first portion including an inner ring and an outer ring configured to generate a first E-field in a first direction, and a second portion having a respective inner ring and the outer right configured to generate a second E-field in a second direction that is orthogonal to the first 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, and it may be a cutout. The slot ring antenna encompasses eyewear optical assemblies. In one example, the slot antenna first portion encompasses a first optical assembly, and the second portion encompasses the second optical assembly. The outer ring may comprise of a common ground plane, which ground plane may extend proximate a bridge of the eyewear. The two portions of the antenna co-exist in very close proximity to each other and support the same frequency band with minimal coupling to each other due to the orthogonal E-fields.
