An Optically Transparent Antenna on Glasses for 2.4GHz WiFi

The optically transparent antenna potential to release the antenna volume constraints in compact mobile devices such as smart glasses. The transparent conductors have a trade-off between optical and electrical properties. Antenna performance is to be maximized to a level where the optical properties are acceptable. This paper reports optically transparent antenna by fine metal mesh that provide us for better resistivity. The proposed antenna is a slot antenna formed between a transparent conductor and a metal form factor, shows a total efficiency better than -4.0dB at 2.4GHz WiFi band.
