Ultra‐wideband DRA integrated with narrow‐band slot antenna
Bibliographic record
Abstract
A new ultra‐wideband (UWB) antenna integrated with a narrow‐band (NB) antenna has been designed and fabricated. The UWB antenna consists of a U‐shaped dielectric resonator fed by a microstrip line. In addition, the proposed structure integrates an NB slot with the same polarisation. The electromagnetic analysis is carried out by using two commercial software tools. To validate the proposed concept, experimental measurements have also been performed. The measured results show that the dielectric resonator antenna (DRA) provides a wide bandwidth from 2.94 to 11.34 GHz (covering the UWB spectrum, 3.1–10.6 GHz) while the slot antenna provides a 2:1 voltage standing wave ratio bandwidth for 5.71–6.13 GHz. Moreover, the proposed design allows an efficient integration with very good isolation between the two ports (transmission coefficient S 21 <−20 dB in the whole operating frequency band).

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.
