Wideband and high‐gain EBG resonator antenna based on dual layer PRS
Bibliographic record
Abstract
ABSTRACT A wideband and high‐gain electromagnetic band‐gap resonator antenna for X‐band operation is presented in this paper. A dual‐layer partially reflective surface with a wide frequency band from 8.3 to 11 GHz is proposed to enhance the 3‐dB gain bandwidth of a simple planar antenna. The measured results indicate that the proposed antenna possesses a relative 3‐dB gain bandwidth of about 33.33%, from 7.95 to 11.13 GHz, with a maximum gain of 13.57 dBi. Moreover, the measured impedance bandwidth is about 35.53%, from 7.8 to 11.17 GHz, which fairly covers the 3‐dB gain bandwidth. Hence, the proposed structure surpasses conventional techniques for widening the 3‐dB gain bandwidth. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:98–101, 2017

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.
