Abstract
ABSTRACT The design and fabrication process of a unique pneumatically controlled capacitive switch is described. The switch, developed for reconfigurable antennas, presents a low‐loss alternative switching mechanism, and avoids the issue of a complicated biasing layout associated with electrostatic actuation in the conducting layer. The closed state of the switch is created by a movable copper‐coated solid slug that bridges a gap in a microstrip line with capacitive coupling. The basis of the switching mechanism is pressurized air causing the physical displacement of the slug inside a confining dielectric channel. Repeatable switching between open and closed states by pneumatically controlling the position of the slug was demonstrated with the fabricated switch. The minimum pressure required to move the slug was measured. This switch was measured from 0.5 to 15 GHz using a Thru‐Reflect‐Line calibration to de‐embed the coax‐to‐microstrip transitions. Insertion loss of 0.2 dB and isolation of 25 dB have been achieved at 5 GHz. The successful fabrication and measurement of the switch demonstrates the viability of applying this technology in reconfigurable antenna designs. © 2014 Wiley Periodicals, Inc.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
