Metasurface Antenna for Gain and Bandwidth Enhancement in 28 GHz Radio-over-Fiber System
Bibliographic record
Abstract
A dual layer metasurface antenna designed for 28 GHz gain and bandwidth enhancement has been integrated with a radio-over-fiber system to demonstrate successful transmission of a 16-QAM 5G NR signal. Measured results for the magnitude of the reflection coefficient and gain of the fabricated metasurface antenna are presented. Good matching along with gain and bandwidth enhancement has been achieved for the 28 GHz mm-wave band. Subsequently a 5G radio-overfiber demonstration is used to evaluate the impact of the improved antenna on EVM (error vector magnitude) performance. Inclusion of a metasurface superstrate reduces the measured EVM from 3.73% to 2.68%. By leveraging the strengths of both metasurfaces and radio-over-fiber, network operators can achieve high-capacity, reliable, and cost-effective communication infrastructures.

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.
