Via-loaded Complementary Spline-based Periodic Leaky-wave Antenna for Broadband Radiation Coverage
Bibliographic record
Abstract
In this research, a unique design technique of one dimensional printed periodic leaky-wave antenna for Ku-band applications is proposed. A unique unit cell is configured based on substrate integrated waveguide (SIV) transmission line that successfully mitigates the open stop-band (OSB) issues providing high gain and significantly improved cross-polar level. The unit cell is composed of a splitted resonant spline slot and two inductive posts to achieve a perfect balanced condition at broadside along with suppressed stop band by exciting n = −1 spatial harmonic. The proposed antenna exhibits a single fan beam that is capable of scanning the visible space from near backfire to near endfire through broadside with the scan range of −46° to +46° within the frequency sweep of 12.1 to 17.41 GHz. Additionally, the inclusion of gap in the Spline slot significantly pulls down the cross polar level better than −28 dB at broadside. The maximum gain of 16.26 dBi and directivity of 17.2 dB are achieved over the band of applications.

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.
