Investigation Into the Vertical Monopole-Like Radiation Mechanism of a Horizontal Dipole on a Periodic Patch-Loaded Grounded Slab
Bibliographic record
Abstract
It was recently demonstrated that a horizontal dipole radiates with a vertical monopole-like radiation pattern when placed near a two-dimensional periodic patch-loaded grounded slab (PLGS). Such a structure has been proposed as a low-profile surface-wave antenna. In this letter, we examine the radiation mechanism of such an antenna. It is indicated in this letter that the vertical monopole-like pattern is generated by the vertical common-mode current flowing on the outside of the coaxial cable feeding the short dipole, and not from the dipole itself. In this manner, the unbalanced horizontal dipole closely resembles a classic T antenna. Furthermore, we examine the propagation characteristics of the surface wave on the PLGS and discuss its contribution to the overall radiation of this antenna. We find that, in the lower frequency range, the PLGS appears insignificant to the antenna radiation. The investigation is carried out by the use of a full wave method-of-moments simulation.

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.
