A novel investigation on printed stretchable WLAN antennas
Bibliographic record
Abstract
In this paper an investigation on the realizability of the fully printed stretchable antennas has been reported. A novel stretchable conductive ink has been developed and utilized in the printing process. A conductivity of 849 S/cm and stretchability up to 300 % is achieved for the ink. The functionality of the ink at the WLAN band is tested by measuring two bowtie slot and patch antennas. The resonance frequency of the patch antenna shifts from 5.7 GHz to 3.5 GHz by stretching its longitudinal length to 65 % more than its original dimension. It is also feasible to stretch the bowtie slot up to 110 % more than its initial length while its resonance frequency moved from 5.2 GHz to 2.6 GHz. The agreement between the simulation and measurement results show that the proposed ink is very useful for the fabrication of the stretchable RF/Microwave circuits and antennas.

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.
