“…It should be noted that photolithography is a subtractive process, in which the desired patterns are obtained via the removal of materials through etching, cutting, drilling, and grinding. [ 58–62 ] Typically, the production process involves multiple procedures, such as photoresist coating, patterning, developing, chemical etching, and cleaning, [ 63 ] as displayed in Figure a. It is expensive due to the multiple‐step processes involved, a number of which must be performed in a cleanroom environment.…”

on several nonplanar objects and worn by humans, they must be mechanically flexible. Moreover, to maintain the abundance of such wireless devices in a smart city and still maintain the aesthetics, it is desirable that they be optically transparent. Finally, to afford this IoT revolution, in which billions of devices are required, the cost of an individual device must be extremely low. As displayed in Figure 1, this new form of transparent RF electronics can help in many smart city applications without affecting the functions of the existing structures where they will be deployed. For example, specially designed periodic structures, namely reconfigurable intelligent surfaces (RIS), can enhance the 5G and beyond communication by increasing the coverage area, spectrum, and energy efficiency. [7] Transparent RIS integrated on buildings, cars, and train windows can optimize the reflection and transmission characteristics of the 5G signal according to the user positions via tunable and switchable devices. [8] Transparent antennas on cars can provide diverse connectivity for radio, GPS, television, smartphones, and so on while maintaining aesthetics. [9][10][11] This can likewise serve as a mainstream technology for autonomous cars, which would rely on radar antennas on the car body. Another example is a transparent frequency selective surface (FSS), which is a periodic structure for selectively shielding from unwanted frequency bands while allowing the bands of interest to pass through. [12][13][14][15][16][17] Other examples of transparent RF electronics include RF circuits, [18] EM absorbers, [19][20][21] RF shielding, [22][23][24][25] and RF energy harvesting. [26,27] A highly suitable approach to realize this new form of mechanically flexible and optically transparent RF electronics is via printing technologies. Printed electronics (PE), as the name suggests, are electronic devices manufactured using traditional printing technologies. Compared with conventional fabrication techniques, such as milling, photolithography, and etching, [11,18,20,28,29] printing has many merits that make it suitable for the subsequent generations of electronics, such as ease of mass production with simple procedures, lower costs, higher throughput, and the ability to work with flexible materials and substrates. PE technologies allow for the direct deposition of various materials, including conductors, semiconductors, and dielectrics, among others, on different flexible substrates to form 2D and 3D patterns. PE has been widely

“…There are various methods of fabricating meshes utilizing microfabrication such as inkjet printing, laser etching, electroplating, and so on [20,21]. The shape of the mesh is mainly used in the form of a square [14][15][16][17][18][19].…”

This paper presents a systematic parameter study on mesh pattern for optically transparent flexible antenna with feedline. In implementing a transparent flexible antenna using a metal mesh, transparency and performance of antenna and feedline are opposite factors. To understand how both elements are affected by the design parameters of the mesh, we analyze the performance of the feedlines and antennas according to the design parameters of diamond and square meshes. Moreover, the effect of the difference in the shape of diamond mesh and square mesh on performance is analyzed. The measured results of the fabricated samples offer the feasibility of implementing transparent feedlines and antennas with similar performance to nontransparent feedlines and antennas.
