Mode-Tunable OAM Antenna System with Polarization Selectivity Characteristic
Bibliographic record
Abstract
This paper presents a new Orbital Angular Momentum (OAM) antenna system with an innovative reconfigurable feeding network and dual-polarized antennas. The 2x4 feeding network generates phase gradients of 0°, 90°, and -90° at its outputs, enabling OAM modes 0, -1, and +1. By integrating a 2x2 uniform circular array with dual-polarized antennas and two copies of the proposed feeding network, the system supports six reconfigurable propagation types, ideal for smart OAM communications. Operating at 2.4 GHz, it achieves phase gradients with a maximum 4° imbalance, and input port reflection coefficients below -15 dB. All in all, the novel configuration of the feeding network, concept of combination of polarization and OAM modes, and ability to generate additional orthogonal reconfigurable beams can be highlighted as the novel parts of this paper.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
