Investigation on the phase centre of ultra wideband circular monopole antennas
Bibliographic record
Abstract
The phase centre of an UWB circular monopole antennas working over the frequency band from 3.1 to 13.5 GHz was determined. The displacement of the coordinate origin on the Z-axis that leads to a minimum change in the phase of the far field was calculated for different thetas ranges at phi =0, 45 and 90 degrees. It was found that although the antenna has a good impedance and radiation pattern bandwidths, its phase centre is moving on the Z-axis with changing the frequency. This movement is within different lambda ranges over the frequency band for different thetas ranges. This information is useful to better understand how well this antenna ill act and where the radiation will be coming from for different angles at different frequencies. More results for other UWB monopole antennas will be shown and discussed during the presentation of this paper in the conference.

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.
