Optically transparent monopole antenna with high radiation efficiency manufactured with silver grid layer (AgGL)

A technology based on a meshed silver/titanium bilayer printed on glass substrate is briefly presented. A sheet resistance equal to 0.054 /sq with 81.3 of optical transparency is obtained. The performances of a monopole antenna made from such a material have been investigated. The measured S₁₁ and gain of the transparent antenna are compared with those of an antenna fabricated from a reflective silver/titanium film, and stand for reference. The transparent antenna provides radiation efficiency better than 85%.
