Abstract
A new dielectric resonator antenna (DRA) is introduced for ultrawideband applications. Three methods of a Z-shaped dielectric resonator, a bevel feeding patch, and an air gap between the DR and the ground plane are used to obtain an ultrawideband impedance bandwidth. The effective dielectric constant and the -factor can be reduced by introducing the air gap. The bevel-shaped feeding mechanism provides a smooth impedance transition from one resonant mode to another. Furthermore, the results show that by applying a Z-shaped DRA, the electric field inside the dielectric is reformed over the desired bandwidth leading to improve the matching. A comprehensive parametric study is carried out using CST to optimize the bandwidth of the proposed antenna. The measurement results demonstrate that the proposed DRA provides an ultra bandwidth of about 120%, ranging from 2.5 GHz to 10.3 GHz for the reflection coefficient less than .

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 it
