Abstract

fetched live from OpenAlex

The microstrip reflectarray is rapidly becoming an attractive alternative to the more traditional parabolic reflector antenna in some applications. Several variations of the microstrip reflectarray have been designed and fabricated. Amongst the many advantages of the microstrip reflectarray, there are also some serious shortcomings that need to be resolved, particularly the issue of limited bandwidth. The constricted bandwidth is largely attributed to: (i) the narrow bandwidth of the patch elements; (ii) the differential spatial phase delay due to an extended path length between the feed and the reflectarray, and (iii) the phase error related to the changes in patch size. In order to improve the bandwidth of the variable-patch-size reflectarray, the major parameter that governs the bandwidth performance of this class of reflectarray, namely the patch length, must be studied more thoroughly so that its effects on the phase variation can be determined. Such is the objective of the present paper.

Teacher imitation

Not 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.
