New trends in planar antenna research
Bibliographic record
Abstract
New antenna concepts are reviewed and discussed. The main focus of this review paper is on some recent activities by the authors at the Royal Military College of Canada and Queen's University in Kingston. Topics include surface-wave launcher (SWL) sources for novel feeding of quasi-optical circuits and new planar antennas at millimeter-wave frequencies. In these configurations, a bound cylindrical TM 0 surface-wave (SW) mode is excited on a grounded dielectric slab (GDS). Planar antenna designs include leaky-wave antennas (LWAs) for pencil-beam, conical-sector and broadside radiation. In addition, end-fire radiation is also possible by reshaping the ground plane realizing a novel surface-wave antenna (SWA). Arrayed placement of such SWLs can also achieve SW beam steering on the guiding surface. By varying the relative phase difference or effective weighting distribution between SWL elements, the generated SW field distribution can be steered and controlled. Using such a novel SWL array, far field beam patterns can be shaped and controlled at a single frequency. These SWLs offer new possibilities for planar antenna feeding systems and novel circuit configurations.

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.
