Broadband Dual-Polarized Cup Dielectric Resonator Antenna With Stable Omnidirectional Radiation Patterns
Bibliographic record
Abstract
A broadband dual-polarized cup dielectric resonator antenna (CDRA) with stable omnidirectional radiation patterns is presented in this correspondence. Both omnidirectional horizontally polarized (HP) and vertically polarized (VP) radiation patterns can be attained by exciting electric-dipole/TM01δmode, TE011+δmode using a coil feeding structure and a planar feeding network, respectively. The coil feeding structure motivates the CDRA's mode and another equivalent electric dipole at nearby frequency to the CDRA mode to extend the bandwidth. A broadband TE011+δmode is excited by the planar feeding network using a double-tuned method. The CDRA is 0.48 λ0×0.18 λ0(λ is the free-space wavelength at the center frequency). A prototype is fabricated and measured, achieving an HP bandwidth of 14.5% and a VP bandwidth of 29.8%. The overlapping bandwidth is 14.5% (3.26-3.77 GHz). The proposed antenna can be used in various wireless communications.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
