Abstract
Abstract A wideband circularly polarized single‐patch single probe‐fed patch antenna is investigated for applications of GPS L5, L2 and Galileo E5a, E5b bands. The wideband circular polarization (CP) is achieved by corner‐truncated square patch and insertion of a thick air layer between the radiating patch and the ground plane. A conducting circular disc is etched on the back side of the substrate to compensate the long inductive probe. The obtained 3‐dB axial ratio (AR) CP bandwidth for 25 and 28.5 mm air layer are 5.9% (71 MHz) and 6.4% (77 MHz), respectively. The later covers the all lower L bands of GPS and Galileo. The realized antenna gain reaches 6.45 dBi over the 3‐dB AR bandwidth. The measured and simulated results are in excellent agreement. © 2012 Wiley Periodicals, Inc.

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 it
