“…Optically transparent antennas at present are available in four kinds: (a) A metal oxide film (for e.g. ITO film)-within the antenna design, a compromise must be made between the light transmittance and surface impedance [209]; (b) Multilayer silver-coated polyester thin film (such as AgHT series)-compared with ITO film, the AgHT film has better conductivity and worse transmittance [210]; (c) An ultrathin metal film made of Cu, Ag, Au, and other metal conductors-such antennas have high radiation efficiency and pretty low light transmittance [211]; (d) Metal mesh antenna it demonstrates the highest radiation efficiency and light transmittance higher than that of the ultrathin metal film. However, it has high requirements for processing technology [212,213].…”

Considering metal oxide nanoparticles as important technological materials, authors provide a comprehensive review of researches on metal oxide nanoparticles, their synthetic strategies, and techniques, nanoscale physicochemical properties, defining specific industrial applications in the various fields of applied nanotechnology. This work expansively reviews the recent developments of semiconducting metal oxide gas sensors for environmental gases including CO 2 , O 2 , O 3 , and NH 3 ; highly toxic gases including CO, H 2 S, and NO 2 ; combustible gases such as CH 4 , H 2 , and liquefied petroleum gas; and volatile organic compounds gases. The gas sensing properties of different metal oxides nanoparticles towards specific target gases have been individually discussed. Promising metal oxide nanoparticles for sensitive and selective detection of each gas have been identified. This review also categorizes metal oxides sensors by analyte gas and also summarizes the major techniques and synthesis strategies used in nanotechnology. Additionally, strategies, sensing mechanisms and related applications of semiconducting metal oxide materials are also discussed in detail. Related applications are innumerable trace to ultratrace-level gas sensors, batteries, magnetic storage media, various types of solar cells, metal oxide nanoparticles applications in catalysis, energy conversion, and antennas (including microstrip and patch-type optically transparent antennas), rectifiers, optoelectronic, and electronics.

“…This opens up a new horizon where paper-thin antennas throughout the microwave spectrum can be pasted onto RF transparent windows of automobiles or buildings to radiate effectively into space. This is similar but with a different approach to the previous research efforts [7], [8] where microstrip antennas used optically transparent metallization, while this approach uses membrane-thin slot radiator with ordinary and nontransparent metallization but small ground plane.…”

A microstrip line on very thin membrane substrate (0.05 mm) is slot-coupled through a thick air substrate (12.7 mm) to excite an L-band radiating patch element. A breadboard unit achieved a relatively wide bandwidth of 100 MHz (8%). Very narrow coupling slot is used with aspect ratio of 160 (conventional slot aspect ratio is between 10 to 30). This new feed design makes the thin-membrane or inflatable array antenna technology more practical. It reduces the number of thin-membrane layers required for a dual-pol wide-band inflatable array from three layers in a previous design to two layers. In addition, this technology allows the thin-membrane array antenna elements to be readily integrated with thin-membrane-mounted transmit/receive (T/R) modules. Calculation shows that, without the patch, the microstrip line and slot combination can also radiate as a paper-thin (0.05 mm) radiator at the L-band frequencies.

An optically transparent antenna with directional radiation pattern is proposed in this paper. This antenna consists of a radiation patch above the transparent glass substrate and a frequency selective surface acting as the ground of microstrip antenna on the back of the glass. The frequency selective surface (FSS) performs well as ground in the working frequency range to achieve directional radiation pattern. A SMA connector is used to feed the antenna. The antenna can operate at the on-board dedicated short-range communication band from 5.725 GHz to 5.85 GHz. Simulations and measurements are carried out to study the antenna performances in terms of impedance matching, gain, and radiation patterns. Both of the simulation and measurement results are shown to illustrate the good performance of the proposed antenna. It is very suitable for car network communication scene.
