A planar cavity based antenna by leaky parallel-plate wave guiding and practical surface-wave launching
Bibliographic record
Abstract
A dual-layer antenna that utilizes bound surface waves for leaky wave excitation is presented for microwave and millimeter-wave applications. Specifically, by placing a superstrate dielectric layer and ground plane on top of a base grounded dielectric slab a resonant cavity can be realized defining a parallel-plate guiding structure. Antenna leakage can be achieved by an annular `bull-eye' grating of slots etched in the top ground plane for two-side beam scanning. In addition, a single pencil beam at broadside can be observed over a large radiating bandwidth (21.9 GHz to 23.9 GHz) with measured antenna gain values > 12.6 dBi from 22.3 GHz to 23.7 GHz. Essentially the bidirectional field distribution on the aperture is excited by a non-directive surface-wave launcher (SWL) source embedded in the bottom ground plane. This dual-layer structure and printed SWL feed may be useful for new parallel-plate wave guide configurations and other planar leaky-wave antennas.

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.
