Frequency scanning long slots array in a ridge gap waveguide technology
Bibliographic record
Abstract
Two different radiating mechanisms are implemented using the ridge gap waveguide (RGW) technology for the design of a frequency scanning antenna with high gain; through a number of radiating slots array. A Quasi-TEM horn of a shaped ridge is designed as a guiding structure to direct the propagating waves in the enclosed air gap between the ridge and the top radiating metallic plate. The first well known mechanism is to introduce one guided wavelength separation between the slots to assure that the slots are in phase. The drawback of such mechanism is the presence of undesired grating lobe. In order to eliminate the grating lobe, another mechanism is introduced, which is newly implemented here in the RGW technology. A non-radiating longitudinal slot is used to split each slot into two halves. Each half is then displaced along the non-radiating slot by a half wavelength. At the feed end, a phase shifter of 180° is introduced. This new arrangements allows a distance of a half wavelength between each two neighboring slots and thus eliminating the grating lobe.

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.
