A gain enhancement of compact UWB antenna based on a single FSS layer
Bibliographic record
Abstract
Abstract The present work introduces a novel low‐profile antenna for UWB applications through the use of a frequency‐selective surface (FSS). The FSS reflector uses a 7 × 7 array with a unit cell of 12.4 × 12.4 mm. By incorporating this periodic structure, the antenna's peak gain reaches 11 dBi, covering a UWB frequency range from 3.01 GHz to 13.5 GHz. Both FSS and UWB antennae are printed on the same type of substrate (FR4‐epoxy). The gap between the FSS layer and antenna is a half wavelength (18 mm) to obtain the best performance. The fabricated optimized antenna prototype shows a reasonable accord between numerical and experimental results. These results are compared to the existing literature designs. Overall, the proposed antenna system has reduced complexity and size, while offering a very wide bandwidth and high gain, making it a good candidate for imminent wideband and high‐gain wireless communication systems.

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.
