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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
