Wideband Cup Dielectric Resonator Antenna With Stable Omnidirectional Patterns
Bibliographic record
Abstract
A wideband omnidirectional cup dielectric resonator antenna (CDRA) is designed by utilizing three modes (DR TM01δ, coil, and monopole modes) for the first time. It deploys the modified coil feeding structure comprising four coil segments and two close-by probes. The four coil segments provide an equivalent magnetic-current loop and the two probes act as an electric monopole. Thus, the modified feeding structure can excite the DR TM01δ mode and two neighbor resonances extending the operating bandwidth. All of these modes have omnidirectional characteristics. To verify the idea, a CDRA is designed, fabricated, and measured. The CDRA is 0.61λ0×0.32λ0 (where λ0 is the free-space wavelength at the center frequency) with a bandwidth of 67.7% (3.28-6.64 GHz). The antenna has stable omnidirectional radiation patterns, high radiation efficiencies, and a low cross-polarized level within the operating bandwidth.

How this classification was reachedexpand
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.
