Dual Differential-Fed 2×2 Phased Array with Reconfigurable Polarization and Radiation Pattern Diversity
Bibliographic record
Abstract
A 2×2 phased array with simplified control of six polarization states and two sets of radiation patterns is presented. Implementing two single pole single throw switches (SPSTs) and three phase shifters results in six different polarization states, including 0°, 90°, ±45° linear polarization (LP), right-hand circular polarization (RHCP), and left-hand circular polarization (LHCP). Moreover, two types of radiation patterns, including a single main-beam at broadside and multi-beams (i.e., 4 Beams) are achieved using the proposed topologies. Configurations of monolithic microwave integrated circuits (MMICs) used in the feed network are presented. The antenna has an operating frequency band of 9.25−9.55 GHz. The peak realized gain for broadside main-beam and 4 Beams at 9.45 GHz are 12.47 dB and 6.57 dB, respectively. The radiation pattern and polarization diversity along with the compactness and relatively high gain of the proposed phase array, make it a suitable candidate for Radar and navigation systems.

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.
