Abstract
A novel switched-beamforming antenna designed using active frequency selective surfaces (AFSS) is presented. The antenna consists of two parts: a source with an omnidirectional radiation pattern and a novel active triangular frequency selective surface (ATFSS) surrounding the source. Each unit cell in the ATFSS structure contains two diamond shaped patches connected with each other by a high-frequency pin-diode. The ATFSS elements are designed using CST microwave studio. The pin-diodes are applied to achieve beam switching. By switching the applied biasing voltage, the ON and OFF states of the ATFSS exhibit reflection and transmission characteristics in the operating WLAN band. By arranging the AFSS unit cells in a triangular structure with three panels and choosing different combinations of the diode states, the beam switching at various azimuthal directions is achieved. To validate this concept, the proposed antenna is fabricated and measured. A good agreement between simulations and measurements in terms of beam directions, reflection coefficient, and gain has been achieved @5.8 GHz.

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 it
