Study and design of ultra-wideband quasi-Yagi antenna based on monopole printing
Bibliographic record
Abstract
Design of a broadband quasi-yagi antenna based on monopole printed loaded hypersurface. The antenna is fed by a microstrip line and consists of a notched rectangular monopole, a reflector loaded with branches, a pilot, and a hypersurface unit. The impedance bandwidth of the antenna is extended by increasing the length of the reflector, notching the rectangular monopole as well as the floor, and the antenna gain is enhanced by adding a high refractive index hypersurface periodic structure on the right side of the antenna. Simulation results show that the antenna has good radiation performance in the operating frequency band 2.53~4.34 GHz, VSWR<2, and the peak gain of the antenna reaches 16.9 dBi, which has the characteristics of wide bandwidth and high gain, and the designed antenna is suitable for the environment of mines and tunnels, and meets the design requirements.

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.
