“…The power level of the VNA was set to -17.0 dBm and the uncorrected S-parameters were measured for each device from 0.1 GHz to 20 GHz. We adopted a multiline Thru-Reflect-Line calibration [6] technique to characterize the propagation constant and reflect reflection coefficient of the CPW lines.…”

Abstract-This paper describes the computer-aided-design (CAD)-assited microwave characterization of coplanar waveguide (CPW) lines formed by ink-jet printed technology on flexible polyethylene terephthalate (PET) substrates. A spacemapping technique is used to link the measured results with simulations and the mapping is used to extract the electrical properties of the ink and supporting dielectric spacer employed during measurements. Results indicate that the losses in lines are predominantly due to the loss tangent of the substrate and the conductivity of the ink. Estimates of the conductivity of the ink and the dielectric constant of the spacer used during measurement were obtained as 2.97 × 10 7 2.97 × 10 7 2.97 × 10 7 S/m, and 1.79 respectively.

“…The same trend was further pushed to produce antennas by brush painting of metallic nanoparticles on wood substrates [6], by inkjet printing on cardboards [7] and on foam [8]. This has made possible the ease of fabrication of active electronics devices on diverse types of low-cost substrates without the need of masks, alignment steps and etching [9], which has sharply lowered the fabrication costs. Another advantage of replacing solid substrate by more suitable ones is in increasing the system reliability especially for applications which may be used in harsh environments such as military ones.…”

Inkjet printing is a low‐cost technique suitable to fabricate flexible electronic devices using solutions of conductive nanoparticles on any type of substrate without material waste as in conventional etching techniques. In this study, a low‐profile wideband coplanar waveguide‐fed monopole antenna operating at 20 GHz is designed and printed using silver nanoparticle ink on polyethylene terephthalate (PET) and on Epson paper substrates. The effects of varying the drop spacing (DS) of the ink on the conductivity of the printed films as well as on the antenna parameters were fully investigated by numerical simulations and by measurements. A conductivity of 1.8 × 107 Ω−1 m−1 was obtained for the films printed on PET using a DS of 30 µm leading to superior antenna performance with an achieved gain and antenna radiation efficiency of 1.67 dB and 96%, respectively. In addition, the size reduction reached 99%. On the other hand, antennas on Epson paper substrate show an |S11| bandwidth <−10 dB extending from 17.18 up to 24.3 GHz, leading to a fractional bandwidth of 34.34%.
