Parabolic Reflector Antenna Design to Generate Pure High Order Vortex Modes at 24 GHz
Bibliographic record
Abstract
Parabolic reflector (PR) antennas are commercially applied to the two Wi-Fi frequencies of 2.4 and 5 GHz in this conference paper. For the generation of vortex waves, a high gain and directive antenna structure is proposed here with PR. It is a unique feature of electromagnetic (EM) waves to have vortex or orbital angular momentum (OAM). OAM technique (known as conical pattern with twisted phase plane) can theoretically increase radio frequency links' capacity and diversity with infinite characteristic mode numbers. On the other hand, it is challenging to implement it in practice due to divergence of pattern and reception quality and capability. Therefore, the PR structure can be considered a promising method to improve the vortex feature of a signal at the generation section. For a long-range dense link, a PR antenna at 24 GHz is designed to address issues related to high order vortex modes (mode 6). This frequency spectrum and other higher frequencies are used to increase the capacity of the backhaul network.

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.
