A novel printed monopole antenna for future ultra‐wideband communication systems
Bibliographic record
Abstract
Abstract In this letter, a novel microstrip line‐fed printed monopole antenna for ultra‐wideband (UWB) short‐range wireless communications is proposed. The proposed antenna consists of a trapezoidal‐shaped patch with two elliptical‐shaped cuts from its edge forming a bell‐shaped cut. Experimental results shows that the designed antenna operates over impedance bandwidth 3.2–11.4 GHz for return loss S11 < −10 dB, which almost covering the UWB frequency bandwidth. Moreover, the antenna has a good omnidirectional radiation patterns in the H‐plane with good gain flatness over the frequency range of interest. The antenna transmission characteristics at different receiving angles are also measured. By embedding a simple narrow U‐shaped slot in the radiating microstrip patch, a notch in the frequency band of 5.0–6.0 GHz is obtained. The proposed antenna is considered a good candidate for UWB short‐range wireless communication systems avoiding the interference of the existing wireless systems. © 2011 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.
