A Controlled Reception Pattern Antenna Array With Dual-Mode Circular Microstrip Antenna Elements for Increased Angular Availability
Bibliographic record
Abstract
Planar-controlled reception pattern antenna (CRPA) arrays suffer from low null resolution at low elevation angles, which results in a diminished angular space available for reception. The null resolution becomes even worse as the array aperture size is shrunk in modern compact CRPAs. Nonplanar arrays have been used to address this issue, but they are high profile and bulky. A novel planar solution, specifically suited for compact arrays, is proposed in this communication. We show that by utilizing concentric dual-mode TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> -TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> circular microstrip antenna elements in an array, an angular availability similar to a spherical array can be achieved. This is demonstrated by studying the array nulling performance in many Monte Carlo trials with randomly polarized interferers, where the adapted array patterns are computed using a simple null-steering algorithm.

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.
