“…[5][6][7] Printing technologies are reliable in terms of scalability, cost-effectiveness, efficiency, and high throughput, so their widespread adoption is essential for low-cost electronics devices, particularly for printed RFID antennas. Currently several different printing techniques are used for the fabrication of electronic devices, such as printed diodes, [8,9] transistors, [2,10] sensors, [11,12] and antennas. [13,14] Another significant advantage of printing techniques is the ability to print on environmentally friendly cellulose-based paper substrates.…”

Printing technologies have emerged as a viable method for the fabrication of various electronic components, including sensors, actuators, energy harvesters, thin‐film transistors and circuits, as well as antennas. However, printing processes have limitations in terms of surface roughness and thickness. Printing conductive structures on novel substrates, such as cellulose‐based sustainable paper, also leads to further challenges linked to the high surface porosity and ink carrier absorption. Herein, the variability of paper‐based printed antenna performance due to different printing processes, ink carrier absorption, and temperature is investigated. The resonance frequency and gain of different printed antennas (e.g., screen, inkjet, and dispense‐printed) are compared in terms of surface roughness, thickness, and resonance frequency. Screen‐printed antennas show better performance compared to other printed antennas. The results show that the resonance frequency of antenna shifts 20, 30, and 50 MHz for screen printed, dispense printed, and inkjet printed respectively, from the nominal 2.6 GHz. In the case of the inkjet‐printed antenna, a clear effect of skin depth is observed, due to the 0.91 thickness. Furthermore, it is demonstrated that the permittivity/dielectric constant of the paper substrate is significantly influenced by ink carrier absorption and temperature variance.

The low‐temperature‐processed amorphous oxide semiconductors (AOSs) exhibit remarkable potentials in large‐area, flexible, and hybrid‐integrated electronics, while the performance and stability of AOS devices highly depend on the proper manipulation of abundant native defects in AOS, especially for AOS Schottky barrier diode (SBD) with the naturally defective metal–semiconductor interface. Here, a hydrogenated‐InGaZnO SBD with a hydrogen‐rich passivation layer (PL) is reported. With the hydrogenation effectively suppressing interface defects and meanwhile donating electrons, a near‐ideal Schottky contact and more‐conductive drift region are simultaneously achieved, as proven by the perfect ideality factor of 1.08, a Schottky barrier height of 0.87 eV, a high rectification ratio ≈4.5 × 108. Moreover, such sophisticated hydrogenation is self‐stabilized by the bilayer structure of PL, contributing to the record‐high stabilities under harsh environmental and electrical stresses.
