Abstract
A phase array antenna of the present invention includes a dielectric layer formed of a material that is optically transparent. An electrically conductive and optically transparent ground plane layer is secured on one side of the dielectric layer. An array of optically transparent antenna elements are positioned over the opposing side of the dielectric layer from the ground plane layer. An optically transparent beam forming network is formed on the dielectric layer on the same side as the optically transparent antenna elements and is operatively connected to the array of optically transparent antenna elements.
