“…* * based on previous paper tanδ measurements [39]; † α for a Kapton substrate losses to aerosol-jetted silver ink lines [22], it can be seen that despite being fabricated on lossier and rougher substrates, and containing an embedded DC-blocking capacitor of up to 44 pF capacitance, the realized screen-printed microstrip lines exhibits lower losses up to 50 GHz. In addition, compared to the only reported printed DC-blocking capacitively-coupled transmission line, [18], the proposed lines exhibit significantly improved insertion losses, as well as a very uniform phase and magnitude response over a 10× wider bandwidth. In addition, based on the simulated and measured response of the proposed line, it is anticipated that the operation bandwidth of the line is higher than 50 GHz.…”

“…Furthermore, despite the growing popularity of additively-manufactured microwave components including multi-layered microstrip lines operating up to 10 GHz [17], there are no reported broadband DC-blocking lines implemented using additive manufacturing on low-cost flexible substrates. To explain, while paper-based capacitively-coupled coplanar waveguides were realized for 1-5GHz applications, their measured S 21 response was highly unstable with an insertion loss over 2 dB/cm, as low as 5GHz, with a non-uniform phase response [18].…”

In this paper, a novel multi-layered microstrip line with built-in parallel-plate capacitors is proposed for DC-blocking applications, with its transmission characteristics measured up to 50 GHz. The microstrip lines are fabricated via screen printing directly onto polyurethane films laminated on standard textile substrates which would otherwise be unsuitable for printing. Compared to a standard microstrip line on the same substrate, the proposed 10 cm-long line on felt (with an embedded 44 pF capacitance) suffers from less than 0.1 dB higher insertion loss up to 4 GHz. Furthermore, varying the overlapping length of the lines and hence the capacitance enables the realization of DC blocking and −3 dB high-pass filtering with pass-bands starting between 88 MHz and 1.2 GHz. This is achieved without altering the cut-off frequency of the microstrip line's mode-free propagation, measured up to 50 GHz, exhibiting a low attenuation of 0.32 dB/mm at 50 GHz on a felt fabric substrate. Compared to a lumped capacitor, the proposed microstripembedded printed capacitor demonstrates a significant improvement in mechanical reliability, withstanding over 10,000 bending cycles, and RF power handling with under 6 • C temperature rise at 1 W. The lines are fabricated on two textile substrates and their transmission characteristics were measured up to 50 GHz, which represents the highest frequency characterization of textile-based lines to date, demonstrating a stable group delay and insertion losses. Based on the proposed multi-layered integration method, low-cost screen-printed microstrip-embedded capacitors on textiles can be used for microwave applications up to mmWave bands.INDEX TERMS Additive manufacturing, capacitors, DC block, high-pass filter, microstrip lines, printed capacitors, radio frequency (RF), textile capacitors, transmission lines.This article has been accepted for inclusion in a future issue of this journal.

This research unveils a transformative methodology for fabricating flexible printed circuit boards (PCBs), focusing on the unique attributes of filter paper substrates. A meticulous parametric exploration scrutinizes critical aspects such as buckling resistance, charging current, plating time, and electrode configurations for copper electroplating. Key findings highlight the exceptional stability of copper electroplating on filter paper, exhibiting robust resistance against environmental variations and bending angles spanning +180° to −180°. Utilizing higher pencil grade material and maintaining a minimum 4 cm distance with a voltage range of 3 to 1.44 V ensures uniform, controlled plating without burning, optimizing the electrode area below 1 cm2for enhanced practicality. The research underscores the longevity and durability of copper‐plated filter paper, with negligible resistance changes even after 1000 folds. Over a year, the shelf‐life assessment emphasizes the excellent stability of electroplated filter paper. Practical applications, including fully functional circuits and a bio‐degradable piano, underscore the versatility and real‐world feasibility of the proposed electroplating technique.
