A novel miniaturized UWB antenna with four band‐notches
Bibliographic record
Abstract
Abstract In this article, an effective design method is presented to design a miniaturized UWB antenna with four band‐notches. By carefully integrating C‐shaped slots, L‐shaped open circuit stub, and T‐shaped parasitic strip onto the primitive miniaturized antenna, four band‐notches (VSWR > 2) could be achieved at 3.38–3.65 GHz, 4.95–6.05 GHz, 7.42–7.78 GHz, and 8.1–8.9 GHz to reject WiMAX, WLAN, X‐band satellite communication, and ITU 8 GHz band signals. Simulated and measured results show that this antenna could operate from 3.15–11.1 GHz (VSWR < 2), and maintain omnidirectional directivity patterns at H‐plane. Moreover, the proposed antenna has a very compact size of 18.6 × 22 × 1.5 mm3. © 2013 Wiley Periodicals, Inc.

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.
