A compact balanced antipodal bow‐tie antenna having double notch‐bands
Bibliographic record
Abstract
ABSTRACT A balanced antipodal bow‐tie antenna is presented for ultrawideband (UWB) applications. Bandwidth enhancement and size reduction are achieved by introducing staircase edging to the peripheral of the patch radiator, and by tapering the microstrip feed balun to generate balanced currents on each branch of radiator. The antenna provides band‐notch functionality by embedding dumbbell‐shaped slots within the radiator, and adding an open‐circuit L‐shaped meander stub. The small and low‐profile antenna can easily be fabricated on a single layer of FR4 substrate with dimensions of 26 × 31 × 1.6 mm 3 . Good correlation is obtained between the simulated and measured results. The antenna operates across 2.8–11 GHz to fully satisfy Federal Communications Commission's UWB specifications. In addition, the antenna provides notch‐bands across 3.3–4 and 5–6 GHz to minimize interference from the WiMAX and WLAN networks. © 2014 Wiley Periodicals, Inc.

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.
