Design and Fabrication of Nonplanar Yagi–Uda Antennas Based on a Partially Conductive Filling Method
Bibliographic record
Abstract
In this letter, a rapid and easy fabrication approach of nonplanar Yagi-Uda antennas is presented. The presented nonplanar Yagi-Uda antenna has a three-layer configuration and consists of several fully and partially-filled vias including one pair of radiator vias, two partially-filled reflector vias, and two partially-filled director vias. All vias are fully or partially filled by the silver conductive polymer (silver conductive epoxy, or SCE). This new partial filling scenario is realized by squeezing a certain amount of SCE in the vias using an accurate pipette. A nonplanar Yagi-Uda antenna prototype is designed and fabricated to work within the X-band. A good agreement is achieved between the measured and simulated results, which confirms the reliability and robustness of this fabrication approach. The measurement results show that for a Yagi-Uda antenna with just two directors, a gain of 10.2 dBi is achieved.

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.
