A novel orthogonal linearly polarized directional antenna for ultra wideband applications
Bibliographic record
Abstract
In this paper, a novel ultra wideband (UWB) Vee dipole antenna with dual linear orthogonal polarization is introduced. The antenna consists of a 4-arm Vee dipole antenna with a novel arm shape fed by two coaxial cables with UWB baluns. The antenna occupies a volume of (0.44 λL× 0.44 λL× 0.44 λL) without the coaxial balun. The boresight gain of the antenna reaches 12 dB with the cross polarization level of less than 30 dB and back lobe level of about 12 dB. The effect of including ground plane and director elements on the performance of this antenna is studied. The preliminary results of this study show that this antenna can be a good candidate medical imaging and as a feed for wideband reflector antennas such as in the Square Kilometer Array (SKA) project.

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.
