Abstract

A multilayer thin film antenna for mobile devices is proposed. The proposed antenna consists of a (indium-zinc-tin oxide) IZTO/Ag/IZTO multilayer film, which is fabricated on a polyimide substrate (ε_r = 3.5) and a copper layer. The centre frequency of the antenna is 1260 MHz. The geometry of the antenna is made up of a coupled loop and two branches. The proposed antenna was fabricated using the DC pulse sputter instrument. The measured and simulated results of the antenna are given. The measured peak gain of the proposed antenna is 1.66 dBi. The transparency of the IZTO/Ag/IZTO thin film on the polyimide substrate is 86%. The advantages of the proposed antenna are high transparency, low resistivity and flexibility.
