A printed quasi‐<scp>Y</scp>agi antenna with dual‐stub‐loaded parasitic strip director for bandwidth enhancement
Bibliographic record
Abstract
ABSTRACT A novel printed quasi‐Yagi antenna with dual stubs loaded on a parasitic strip director has been presented. The impedance bandwidth is analyzed and compared when we add or eliminate the parasitic strip director. Then, two open stubs are loaded on the strip to excite an additional resonant mode, which lead to a wider impedance bandwidth. To demonstrate the effectiveness of this design, an antenna prototype is fabricated and tested. Experimental results show that the antenna provides a bandwidth ranging from 4.4 to 9.3 GHz and within the whole band larger than 4.1 dBi gain is achieved. Additionally, the proposed antenna presents a stable end‐fire radiation directivity and low cross‐polarization level at different frequencies with a compact structural size of 35 mm × 26 mm. © 2016 Wiley Periodicals, Inc.

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.
