Hautcoeur, X. Castel, F. Colombel, M. Himdi, E. Motta Cruz] In this paper, transparent printed lines used in microwave radiating structures are studied. Two transparent wire monopole antennas and an opaque reference counterpart are presented, compared, and discussed. The first transparent antenna was fabricated from a transparent conductive AgGL coating (silver grid layer: a silver/titanium bilayer deposited on a glass substrate and meshed by a standard photolithographic wet etching process). It exhibits optical transparency T of 59.2±0.1% in the visible-light spectrum and sheet resistance R □ of 0.017±0.001Ω/□. The second transparent antenna was fabricated from a usual transparent conducting multilayer of indium tin oxide/silver/indium tin oxide, also deposited on a glass substrate. It exhibits optical transparency T of 71.3±0.1% and sheet resistance R □ of 5.05±0.05Ω/□. Both transparent wire monopole antennas have been characterized for microwave performance and compared with an opaque reference counterpart made from a continuous silver/titanium bilayer deposited on the same glass substrate (T=0%, R □=0.0025±0.0002Ω/□). Microwave measurements show similar performance for the transparent AgGL antenna and opaque reference counterpart. At 2.05GHz, their maximum measured gains are both 4.4±0.3dBi. Conversely, the transparent indium tin oxide/silver/indium tin oxide antenna presents significant ohmic loss due to its sheet resistance value and consequently a low measured gain value (−2.1±0.3dBi maximum). This study demonstrates the relevance of the AgGL coating in the fabrication of transparent wire monopole antennas.
