Abstract:
An optically transparent antenna stack includes at least two stacked optically transparent antennas. Each antenna includes an electrically conductive metal mesh including a plurality of interconnected electrically conductive metal traces defining a plurality of enclosed open areas. The metal mesh of each antenna and each lead has a percent open area greater than about 50%. The at least two stacked optically transparent antennas includes a first antenna configured to operate over a first, but not a second, frequency band and a second antenna configured to operate over the second, but not the first, frequency band. The optically transparent antenna stack has an optical transmission of at least about 50% for at least one wavelength in a wavelength range from about 450 nm to about 600 nm.
