“…35 More recently, meander inductors and fully printed inductors have been shown with Q's approaching five. 36,37 A 25 nH inductor with a Q approaching nine was also shown in 2014. 38 All of these printed inductors utilize nanoparticle ink as well as a sintering temperature greater than 150 0 C. In order to make repeatable, quality RF components by inkjet, a robust metal ink with high conductivity is required.…”

Currently, silver nanoparticle based inkjet ink is commercially available. This type of ink has several serious problems such as a complex synthesis protocol, high cost, high sintering temperatures (~200 0 C), particle aggregation, nozzle clogging, poor shelf life, and jetting instability. For the emerging field of printed electronics, these short comings in conductive inks are barriers for their wide spread use in practical applications. Formulating particle free silver inks has potential to solve these issues, and requires careful design of the silver complexation.The ink complex must meet various requirements, such as in-situ reduction, optimum viscosity, 2 storage and jetting stability, smooth uniform sintered films, excellent adhesion, and high conductivity. This study presents a robust formulation of silver-organo-complex (SOC) ink, where complexing molecules act as reducing agents. The 17 weight percent silver loaded ink was printed and sintered on a wide range of substrates with uniform surface morphology and excellent adhesion. The jetting stability was monitored for 5 months to confirm that the ink was robust and highly stable with consistent jetting performance. Radio frequency inductors which are highly sensitive to metal quality were demonstrated as a proof of concept on flexible PEN substrate. This is a major step towards producing high quality electronic components with a robust inkjet printing process.

“…The 3-D EM model of the octagonal spiral inductor, which is built in HFSS, includes an additional top air box that is required for defining the boundary of the EM enclosure. And around the octagonal spiral inductor there is a ringshaped ground plane, which is the replacement for background metallization and serves as the current return path [13]. The distance between octagonal spiral inductor and ground ring is fixed at 50 µm, and the width of the ground ring is about 100 µm.…”

“…Some discrete inductors have already been fabricated on polyimide substrates, but they operate in relatively low frequencies and cannot be monolithically integrated with flexible TFTs and PIN diodes [11]. In addition, other flexible substrate-based approaches, such as design and modeling of high-Q coplanar waveguide (CPW) inductors, low-cost CPW meander inductors utilizing ink-jet printing, and vertically-integrated inkjet-printed high-performance inductors [12,13,14], have been reported. However, to date, there has been very little investigation into the characterization of spiral inductors on flexible substrates.…”

This paper describes the design and fabrication of flexible radiofrequency inductors integrated on a polyethylene terephthalate substrate. Experimental and modeling results for the RF responses of flexible inductors are reported. Investigations and analysis have been conducted on the effects of layout and process parameters on the frequency responses of inductance, quality factor and self-resonant frequency of the spiral inductors. The influence of bending strain on the performance of spiral inductors is also investigated based on measurement and modeling results. The analysis provides guidelines for designing the flexible spiral inductors towards the flexible monolithic microwave integrated circuits on a plastic substrate. Keywords: characterization, flexible, plastic substrate, quality factor, selfresonant frequency, spiral inductor Classification: Electron devices, circuits and modules References

“…Inductors designed by using fractal geometry could potentially solve this problem. Fractal inductors were first reported in [4][5][6] but suffer from anticurrent pathways. An intuitive study of mathematically defined fractal space-filling inductors was carried out in [7][8][9].…”

This paper presents fractal-based inductors for industrial, scientific, and medical applications in a frequency range of 3-500 MHz. The proposed inductors are designed based on the Hilbert space-filling curve and omega-shaped space-filling curve. The fractal inductors are designed and simulated by using a full wave high frequency structural simulator. The Hilbert curve-based fractal loop inductor and omega curve-based fractal loop inductor achieve improvements in the inductance value of 21% to 31% and 11% to 30.88%, respectively, over reported standard inductors. The printed inductors are constructed on 3.2 mm RT/Duroid 5770 substrate and measured with a network analyzer (E8363B). It was found that the experimental results are almost in good agreement with the simulation results. It was also observed that the proposed fractal inductors have poor radiating power, indicating no significant electromagnetic radiation.
