Comparison between CRLH zeroth-order antenna and series-fed microstrip patch array antenna
Bibliographic record
Abstract
A metal-insulator-metal (MIM) composite right/left-handed (CRLH) series-mode zeroth-order resonant antenna (ZORA) optimized for the 24 GHz ISM band is presented and compared to a series-fed patch array (SFPA) antenna. The CRLH ZORA exhibits superior performances for relatively short lengths (≪ 3λ 0 ) whereas the SFPA may performs better, depending on the specific design, when the length is very long (≫ 5λ 0 ), so that the resonant antennas operate as leaky-wave antennas with a leakage factor proportional to the density of the radiators along the structure. To our knowledge it the first time that the leaky-wave operation of an electrically very large “resonator” has been explicitly identified. The ZORA is particularly recommended for average electrical sizes in the order of 2λ 0 , where it should be systematically superior to a SFPA.

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.
