Abstract
A hybrid dielectric resonator antenna (HDRA) with a single-probe generating circular polarization (CP) simultaneously at X and Ku-bands is presented in this article. A novel hybrid structure of semi-circular patch and semi-cylindrical dielectric resonator (DR) of equal radius are combined with a single-point probe feed to achieve dual-functional wide CP bands. The asymmetric nature of the semi-circle and semi-cylinder produces two orthogonal modes in their respective bands for CP radiation. The measured impedance bandwidth obtained by the proposed structure is 36.49% (3750 MHz) at X-band and 14.23% (2100 MHz) at the Ku-band range of frequencies. Axial ratio (AR) bandwidth of 30.39% (3100 MHz) is obtained at X-band and 13.24% (1950 MHz) at Ku-band. The measured gains are 9.54 dBic at 9.6 GHz and 6.55 dBic at 15 GHz. An excellent agreement between the computed and measured results validates the design of the dual functional circularly polarized HDRA.

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 it
