“…The radiation patterns, gain, and efficiency of the proposed antenna are measured using the Satimo StarLab System at KAUST. [44][45][46][47] It should be noted that it is not possible to use the gun heater inside the Satimo StarLab System for measurement. As a proof of concept, to carry out the measurements in the chamber, a simple biasing circuit is designed to supply DC current of 50 mA to activate the VO 2 switch, as shown in Figure 11.…”

This article proposes an additive manufacturing compact (30 × 36 × 0.125 mm3), flexible, and reconfigurable antenna with the ability to switch between wideband and dual‐band for wireless electronic devices used in the fifth generation (5G) systems and wireless local area network (WLAN) systems. The antenna consists of a folded branch line and an inverted L‐shape branch as radiator, and a slot on the ground plane. A vanadium dioxide (VO2) switch is screen‐printed on the folded branch line to reconfigure the operation frequencies. The antenna is optimized to operate for a wide bandwidth between 2.46 and 4.3 GHz when the VO2 switch is in the “OFF” state. The antenna exhibits dual narrow‐bands at frequencies of 2.4 and 5.2 GHz when the VO2 switch is heated up to 85°C or when a DC current of 50 mA is applied. Simulation and measurement show that the performance of the antenna remains relatively stable under different bending conditions in both the “ON” and “OFF” states of the switch. The operating frequencies can be independently controlled, and a guideline is discussed to design the antenna for other frequencies.

“…The radiation patterns, gain, and efficiency of the proposed antenna with severe bending of R=20, ∞, and -20 mm are measured using the Satimo StarLab System at the King Abdullah University for Science and Technology (KAUST) [42,43]. As the antenna has a wide bandwidth of 1.77-6.95 GHz, we select the frequencies of 2.4, 3.5, and 5.2 GHz to study the radiation patterns.…”

A flexible, wideband, and screen-printed antenna is proposed. The antenna is coplanar-waveguide (CPW) and composed of two inverted L-shape elements, a matching stub, and a defected ground structure (DGS), with a total area of 55 × 40 × 0.125 mm3. Studies show that the DGS can significantly increase the antenna bandwidth from 30% to 119% without sacrificing the size. The antenna has a wide measured bandwidth of 1.77-6.95 GHz, and a measured peak gain and efficiency in the ranges of 2.5-5.9 dBi and 60%-90%, respectively. Furthermore, both simulation and measurement confirm that the performance of the antenna is relatively stable under the bending conditions with various curvature radii.

“…Furthermore, PE technologies are being rapidly adapted by the RF community, and some RF designs have recently been presented using printing methods. [31][32][33][34][35][36][37][38][39][40] However, PE also suffers from some limitations. As compared to the conventional clean roombased technologies, such as photolithography, PE processes have somewhat lower resolution, thus feature sizes are in the range of microns.…”

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
