Abstract
Mechanically reconfigurable antennas have the potential to provide a large range of antenna reconfiguration and to have a lower cost than other reconfigurable technologies. Solid state devices in the RF signal path can cause distortion and power limiting, but such issues can be averted by keeping them out of the direct RF signal path. In this paper, new smart material technologies, namely electro-active polymers and shape memory alloy actuators, are presented as potential candidates to implement mechanically reconfigurable antennas. A review of some proof-of-concept reconfigurable antenna prototypes using these technologies is presented, including the advantages and disadvantages for the antenna applications.

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
