Additively-Manufactured, Magnetically Controlled, Frequency and Polarization Reconfigurable Phased Array Antenna
Bibliographic record
Abstract
An additively manufactured phased array antenna is presented in this work that provides simultaneous reconfiguration in frequency, polarization, and beam direction solely in response to magnetic tuning of the underlying ferrite substrate. This design obviates the need for integrated active components, which have been fundamental elements enabling tuning operation in traditional reconfigurable array antennas. The array element of the proposed array antenna consists of a waveguide-based phase shifter, realized by printing metallic walls on a ferrite substrate, which is then monolithically integrated with a printed circular patch antenna. Depending on the magnitude and polarity of the applied magnetic field (solenoids) to the patches, the array antenna can operate in a linearly polarized (LP) mode at 7.2 GHz or in dual circularly polarized (CP) modes in two continuously tunable frequency bands, 5.9–6.5 GHz and 7.6–7.95 GHz. Simultaneously, when magnetic field is applied to the phase shifters, continuous beam steering within ±25° of the boresight can be realized (±35° when fully saturating the ferrite at the phase shifters). To the best of the authors’ knowledge, this is the first implementation of an additively manufactured and fully magnetically controlled array antenna of this versatility.

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.
