An Antenna Advance for Cognitive Radio: Introducing a Multilayered Split Ring Resonator-Loaded Printed Ultrawideband Antenna with Multifunctional Characteristics
Bibliographic record
Abstract
In this article, we present a new design concept for a multifunctional antenna providing single/dual frequency-notched ultrawideband (UWB) capability and its complementary multiple narrow-band functionality from a printed coplanar waveguide (CPW)-fed annular-ring monopole antenna (ARMA). We achieved the proposed multiple antenna configurations by loading square split-ring resonator (SRR) pairs of different dimensions beneath the substrate and above the superstrate, along with copper strips suitably positioned on the CPW feeding section of the antenna. The proposed antenna is compact, because of SRR loading in the substrate and superstrate, which provide seven different antenna functionalities/responses originating from a single radiating annular-ring monopole printed on a dielectric substrate.

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.
