Broadband Circularly Polarized Antenna Based on Integrated Substrate Gap Waveguide
Bibliographic record
Abstract
This paper proposes a new broadband circularly polarized (CP) antenna for 5G millimeter waves based on the integrated substrate gap waveguide (ISGW). The broadband circularly polarized antenna etches a rectangular slot on the PEC on the upper surface of the ISGW, and then adds two rectangular perturbation patches of different shapes on the rectangular slot, thereby realizing circularly polarized wave radiation. To expand the 10dB return loss bandwidth and axial ratio bandwidth of the slot circular polarization antenna based on the substrate integrated gap waveguide, a new dielectric plate is added above the ISGW, and a cross-shaped patch is added above the dielectric plate. This cross-shaped patch not only functions as a parasitic patch but also circularly polarized radiation, thereby achieving the purpose of expanding the 10dB return loss bandwidth and axial ratio bandwidth of the circularly polarized antenna.

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.
