An optically transmissive antenna including an optically transmissive aperture for a slot-type configuration antenna fabricated on a high transmission substrate; coplanar waveguide feedlines formed on the substrate, the coplanar waveguide feedlines defining a center portion and an exterior portion; a first connection point for connecting the center portion to a first conductor; and a second connection point for connecting the exterior portion to a second conductor. The substrate can be rigid or flexible. Also a method of making the antenna including the steps of selecting a high transmission substrate; sputtering the substrate with a highly transparent conductive layer; removing the highly transparent conductive layer from the substrate to form an aperture and a pair of coplanar waveguide feedlines for the antenna. The antenna can be connected using micro-coaxial cable.
