Modified Meander Line Broadside Scanning Periodic Leaky Wave Antenna With Gain Enhancement Antenne à ondes de fuite périodique, à ligne en méandre modifiée, avec balayage latérale et gain amélioré
Bibliographic record
Abstract
In this work, a meander line (ML) periodic leaky wave antenna (LWA) is proposed with gain improvement and broadside scanning capability. A longer ML length is taken in a fixed unit cell period to improve the gain. A longer ML brings more space harmonics (SHs) in the radiation region. Therefore, the geometry of the ML is modified to obtain impedance matching at SHs transition frequencies at 8.35 and 10.45 GHz. The antenna covers the frequency range from 8 to 11 GHz in the X-band with the optimized broadside frequency (<inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$f_{B}$ </tex-math></inline-formula>) at 9.4 GHz. A maximum gain of 15.5 dBi is achieved in <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$6.25\lambda _{0}$ </tex-math></inline-formula> antenna length. This antenna is a potential candidate for use in modern wireless communication where high gain is required in a small footprint area.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
