Pattern reconfigurable Yagi‐Uda antenna with seven switchable beams for WiMAX application
Bibliographic record
Abstract
Abstract In this paper, a pattern reconfigurable printed Yagi‐Uda antenna with linear polarization is presented. The proposed design consists of three parts, including a driving element centered between two other parasitic elements. To achieve pattern reconfigurability, the approach of Yagi‐Uda configuration is employed, where the positions of the director and reflector are exchanged using PIN diodes. The proposed antenna employing six PIN diodes is designed to radiate the main beam at seven scanning angles (−60°, −40°, −20°, 0°, 20°, 40°, and 60°). The beam tilt depends on the size of the antenna's partial ground plane. The proposed design is simple in structure realized on a single substrate board of dimensions 75 × 70 mm2. The measured peak directivity obtained at various scanning angles is about 6.5 dB. The simulated and measured results are in good agreement. The proposed reconfigurable antenna is suitable for WiMAX applications operating around the frequency of 3.6 GHz.

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.
