A <scp>circularly polarized</scp>, high aperture efficiency metasurface antenna
Bibliographic record
Abstract
Abstract A circularly polarized, high aperture efficiency antenna based on metasurface (MTS), inexpensively fabricated using a standard printed circuit board (PCB) technology, is presented. An array of 8 8 cross‐shaped resonators was designed to operate at 3.1 GHz with a 12 cm 12 cm (i.e., 1.24 1.24 ) footprint size. Each resonator was double fed (by two lines) with appropriate phases to achieve circular polarization. Full characterization of the designed antenna was achieved using full‐wave simulations. The MTS antenna was fabricated using a multilayer PCB technology and experimentally tested. A good agreement between the simulation results and measurements was observed. According to the measurements, with a realized gain of 11.1 dBi, the antenna has an aperture efficiency of 66.7%, which is high compared to many other antennas.

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.
