Polarization‐reconfigurable microstrip antenna with a fixed frequency band using a single switch
Bibliographic record
Abstract
ABSTRACT This article proposes a reconfigurable microstrip antenna that changes its polarization with only a single switch at a single frequency band. The antenna consists primarily of a square ring and a square patch, with a foam layer. When the connection status between the square ring and the ground is changed between shorted and open status, the linear polarizations are switched. The resonant frequency of the antenna using a single switch reported previously has been shifted, but the proposed antenna in this article exhibits a fixed resonant frequency. The design principle is as follows: The square‐ring printed on the dielectric substrate has inherent narrow bandwidth, but we found that its polarization‐switching characteristics existed over the broad band. The square patch is placed above the square ring, and it provides a broad bandwidth while maintaining polarization diversity. The performance of the antenna is successfully demonstrated via simulation and measurement. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:57–60, 2014

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.
