Optically transparent ultra-wideband antenna

This paper investigates the fundamental properties of metallised elastomers at microwave frequencies for microwave transmission line and wireless antenna applications. Stretchable or elastic antennas will significantly expand stretchable electronics applications both in the communication and biomedical sectors. Fundamental electromagnetic characterisations of elastic transmission line and antennas are evaluated using simulation software CST. A self compensating elastic antenna is presented.

Transparent microstrip antenna with fluorine-doped tin oxide (FTO or SnO 2 :F) patch is studied here. The authors make use of spray pyrolysis technique to deposit FTO transparent patch on a Pyrex glass substrate. The deposited FTO patches show high optical transmittance (about 80-90%) and low electrical surface resistance (as low as 7 Ω/□). Two transparent microstrip patch antennas (with conventional conductor as ground plane), which are fed by proximity coupling at 2.5 and 5 GHz resonance frequencies, are fabricated and their radiation properties are presented and compared with copper patch antenna counterparts. In order to reduce the conductor loss of the antenna and ameliorate antenna efficiency, thick substrates should be used. The 2.5 GHz antenna shows low efficiency and significant loss in transparent layer but the 5 GHz one shows 3.63 dBi maximum gain and only ∼0.83 dB degradation in comparison with the copper patch antenna.

“…In recent years, transparent conducting material (TCM) has been a critical component in many photo electronic devices such as liquid crystal displays (LCD) [1], solar cells [2], organic light emitting diodes (OLED) [3] and antennas [4][5][6]. Traditionally, this role has been well served by ITO (Indium tin oxide) material.…”
