Design of Ultra-Wideband Optically Transparent Antenna

摘要

This paper proposed an optically transparent antenna designed with indium tin oxide (ITO) film. ITO is a transparent material with good electrical conductivity. The antenna made of ITO material has light-transparent characteristic compared with the antenna made of traditional metal, and can be applied to special scenes such as window glass and display screen. The working frequency band of the antenna is 0.8-6 GHz. This band covers 2G, 3G, 4G and WLAN bands. The main radiator of the antenna adopts a self-complementary structure and is fed with a gradual structure, thus the antenna has ultra-wideband characteristics.
