Mixed boundary semicircular and 120 degrees -sectoral microstrip antennas
Bibliographic record
Abstract
120 degrees -sectoral microstrip antenna and mixed boundary semicircular antennas are analyzed using the Green's function approach and segmentation methods. The sectoral microstrip antennas with sectoral angles less than 180 degrees can be used to reduce mutual coupling between elements for the same interelement spacing. The mixed boundary microstrip patch antennas appear very promising for building arrays where mutual coupling between elements can be controlled by having various combinations of electric and magnetic walls for elements. The Green's functions of mixed boundary sectoral elements have been developed using the method of expansion in a series of eigenfunctions. The computed input VSWRs (voltage standing wave ratios) and bandwidths agree well with experimental results. The 120 degrees -sectoral antenna has more bandwidth (3.6%) than the circular antenna (3%) and is smaller in size. The large difference in bandwidths of two mixed boundary semicircular antennas suggests that the straight edges radiate more than the circular edges.>

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
