Abstract
Eyewear including a see-through display including an optical waveguide module and one or more integrated antennas. In one example, the antenna is disposed on one of the non-active waveguide substrates, which non-active waveguide substrates are used as encapsulants to protect the waveguide active layer from environmental factors and do not have an active optical function in the waveguide operation. In another example, the antenna is disposed on one of the active waveguide substrate surfaces opposite another active waveguide substrate. As a result, there is a large lee-way available in patterning desired antenna shapes, length, and area on these surfaces using optically transparent, high conductivity materials. The antenna is not subject to some design constraints and compromises.
