For the last decade, optically transparent antennas have been a topic of research for applications ranging from satellite communication to window embedded telecommunications. The most common material used for transparent antennas has so far been Indium Tin Oxide (ITO). However, the long term availability of indium due to worldwide shortages and increasing prices is of great concern, necessitating the exploration of replacement materials. Among the most promising candidates is zinc oxide heavily doped with gallium (GZO), which can be produced in the form of thin films with conductivity comparable to that of ITO. In order to study the efficacy of GZO transparent antennas, a printed planar‐dipole antenna was designed and fabricated. The antenna operated in the 2.4 GHZ Industry science and measurement (ISM) band with a return loss of approximately 13 dB. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:773–777, 2017

“…3 for different electrical conductivities. It shows that for plausible surface resistance for transparent antenna applications (less than 10 Ω/□) the thickness of the FTO layer is much smaller than the skin depth, especially for frequencies below Ku‐band, which causes significant losses and current density deformations in microstrip patch antenna [5].…”

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.

“…The basis of the proposed design is a coplanar proximity feed as reported in [13] and [14], where the feed is an open-ended microstrip line. There are two different coupling mechanisms for this type of feeding technique: capacitive and inductive coupling.…”

A circularly polarized meshed patch antenna design is presented. The proposed antenna consists of two square meshed patches, which generate two orthogonal linear polarizations at two slightly different frequencies. A common proximity feedline is utilized to excite the two patches, and a 90 phase difference can be achieved between the two resonant frequencies, which is needed for circular polarization. The overall structure of this antenna is highly compatible with solar panels; thus, it is of great significance for small satellite applications. The measured results of the antenna prototype show that it has a 3-dB axial-ratio (AR) bandwidth of 15 MHz, a 10-dB impedance bandwidth of 2%, and a gain of 5.15 dB at its center frequency 2.47 GHz.Index Terms-Circular polarization, meshed patch antenna, solar cell integration.
