Ultrawideband Large Continuous Scanning NPRIM Leaky-Wave Antenna With Pole–Zero Cancellation-Based Suppressed Stopband
Bibliographic record
Abstract
This letter presents a novel metamaterial-inclined negative/positive refractive index microstrip transmission line (NPRIM-TL) that transforms into a novel leaky-wave (LW) an tenna design with large angle continuous beam scanning function alities. The arrangement in essence features composite right/left handed (CRLH) properties exhibiting frequency scanning ca pability from −86° to +74° through broadside. Incorporating matching stub with the NPRIM-TL-based unit cell, an unique pole-zero cancellation technique is further realized to benchmark the complete suppression of open stopband. A nine unit cell antenna model is manufactured and experimentally validated as a proof of concept for seamless beam scanning throughout the X band. The proposed antenna supersedes the previous prototypes by offering miniaturization (1.9λ0), ultrawide-bandwidth (72%), optimum gain (13 dBi), low sidelobe level (< − 15 dB), and suppressed cross-polarization (< − 20 dB), highlighting its prac ticality for next generation wireless communication 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.
