A novel miniaturized V-shaped monopole antenna for GSM/WiMAX/WLAN applications
Bibliographic record
Abstract
Abstract This paper presents a novel miniaturized triple band V-shaped antenna (VSA). The miniaturization and the triple-band operation are obtained by performing two V-shaped turns on the metallic strip. The proposed antenna is printed on a single FR4 substrate and fed using the coplanar waveguide (CPW) technique. It operates in three frequency bands, [1.6–1.95 GHz], [2.8–4.4 GHz] and [5.4–5.8 GHz], with stable bidirectional radiation patterns in both E- and H-planes. A prototype of the designed antenna is fabricated and tested where the observed good agreement between simulated and experimental results indicates that the proposed structure, having a reasonably compact size of 0 . 0166 λ 0 2 $\text{0}{\text{.}0166\lambda }_{0}^{2}$ , is suitable for GSM [1800 MHz], WiMAX [3.4–3.77 GHz] and WLAN [5.725–5.825 GHz] 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.
