Aerosol Jet Printed, Microwave Microstrip Ring Resonators for System-In-Package Applications
Bibliographic record
Abstract
This article presents the design, simulation, and fabrication of printed microstrip transmission line (TL) and microwave ring resonators using aerosol-jet printing for system-in-package applications. The printed TLs are 8 mm long and their S-parameters are measured over a wide bandwidth ranging from 1 to 26 GHz. Their insertion loss ranges between 0.02 dB/mm at 1 GHz and 0.56 dB/mm at 26 GHz. Ring resonators were designed and printed to operate at center frequencies of 15.5, 17.5, 19.5, and 21.5 GHz by tuning the size of the ring. Variability studies are carried out to evaluate the ability of the printing process to fabricate reproducible devices. The coupling gap is optimized in order to minimize the insertion loss in the ring resonators without compromisingQ-factor. The simulations show good agreement with the experimental results. The ability to print both conductors as well as dielectrics for the fabrication of microwave resonators demonstrate the potential for in-package integration of RF resonators for low-cost sensor applications.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
