Design of Dual-Band Transparent Antenna by Using Nano-Structured Thin Film Coating Technology
In this paper, we proposed the dual-band transparent antenna by using nano-structured thin film coating technology for GPS/Wi-Fi applications. The proposed nano-structured thin film structure is based on “activation” process in the fabrication flow. The activation process will transfer the nano-structure of thin film from disorder to order arrangement. Therefore, the coated thin film is having the characteristic of high transmittance and low resistivity. The proposed antenna has an operating bandwidth is found to be 1420–1720 MHz and 5290–6030 MHz. The transparent dual-band antenna can apply on the applications of 3Cs, wearable devices, and cars.
