Wideband FSS as reflector for circularly polarized millimeter-wave antenna
Bibliographic record
Abstract
A wideband frequency selective surface (FSS) resonating at V-band frequency is proposed in this paper. It can be used as reflector for circularly polarized millimeter-wave antennas. The FSS unit cell is having two similar spiral shapes separated by a substrate at the center. It provides a wideband width of 20 GHz from 50 GHz to 70 GHz for both TE and TM modes. The proposed FSS is used as a reflector for a CPW fed circular polarized 4 × 1 circular slot array antenna. The antenna array with 13 × 5 FSS panel is simulated to obtain an impedance bandwidth of 33%. Indeed an enhanced gain of 10.2 dBi is obtained and axial ratio maintained less than 3 dB in 55–65 GHz band of frequency.

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.
