Monolithic-Integrated MEMS-Tunable Reflective Cell for Ku-Band Mobile Satellite Two-Way Connectivity
Bibliographic record
Abstract
This paper presents the design and measurement of a single-layer micro-electromechanical system (MEMS)-tunable reflective unit cell with orthogonally polarized dual bands for Ku-band mobile satellite connectivity. Six capacitive MEMS switches across each slot of a cross-slotted patch tune its reflection phase at 12 GHz (reception) with vertical polarization and 14 GHz (transmission) with horizontal polarization. This unit cell provides four phase states with overall phase swing of 200° and 180° and average reflection amplitude of -0.79 and -0.69 dB at the lower and upper bands, respectively. This unit cell can be used for generation of an independently controlled beam at each of its operating bands. A monolithic process is also developed for the fabrication of this reflective cell along with the dedicated dc bias network. For unit cell measurements, a custom-designed waveguide setup with four DC pins was fabricated for simultaneous and independent control of all MEMS switches. The measurement results are in good agreement with simulations.

How this classification was reachedexpand
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.
