Performances of transparent monopole antenna versus meshed silver layer (AgGL)

In this study, a technology based on a meshed silver/titanium bilayer printed on glass substrate is briefly presented. Three transparent monopole antennas made from such a material show sheet resistances and optical transparencies ranging from 0.014 Ω/sq to 0.054 Ω/sq and from 56.3% to 81.3% respectively. We investigate the performances of these transparent monopole antennas. Experimental S11 and gains are compared with those of a reference antenna fabricated from a light reflecting silver/titanium film. Transparent antennas provide radiation efficiency better than 85%.
