A compact circular slot UWB antenna with multimode reconfigurable band‐notched characteristics using resonator and switch techniques
Bibliographic record
Abstract
Abstract In this article, we propose a circular slot ultrawideband (UWB) antenna with multimode reconfigurable dual band‐notched characteristics. By using a two‐stage T‐shaped stepped impedance resonator (TS‐TSIR) and a parallel stubs loaded resonator (PSLR), dual band‐notched function is achieved to reject worldwide interoperability for microwave access, WLAN, and X‐band signals. The multimode reconfigurable band‐notched characteristic is realized by integrating four switches onto the TS‐TSIR and the PSLR. Simulated and measured results show that this antenna, with multimode reconfigurable characteristics and dual band‐notched function, can operate from 2.7 to 12 GHz (VSWR<2), which includes the entire UWB band. This antenna maintains omnidirectional radiation patterns that is suitable for UWB applications. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:570–574, 2014

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.
