360-degree beam steering antenna based on subsrate integrated frequency selective structure
Bibliographic record
Abstract
In this paper, we propose a new method for designing mm-wave beam steering antennas with dual polarization and 360° azimuth beam steering angular range. To achieve 360° beam steering, we have added several new features to our previous 180° beam steering antennas based on reconfigurable substrate integrated frequency selective structures and PIN diodes. First, transitions from radial waveguides to microstrip lines are designed to feed the radiating elements. Then, the microstrip lines are bent to leave space for RF connectors. In the next step, meander-line microstrips are optimized for equal-phase and equal-amplitude excitations of the radiating elements. Finally, holes are inserted in the printed circuit board in order to place the RF connectors. Based on the proposed design methodology, a dual polarized 360° beam steering antenna operating at 28 GHz is presented. Full-wave simulation results are shown to validate the proposed concept and an antenna prototype was fabricated.

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.
