A Multi-Beam Antenna Using a Partially Reflective Surface for 5G Applications
Bibliographic record
Abstract
This paper presents a multibeam Fabry-Pérot cavity (FPC) antenna capable of radiating at different angles from broadside. The proposed design consists of a metallic wall, a main radiator with a tilted beam, and a metasurface that functions as a partially reflective surface (PRS) positioned above the structure. The metasurface is designed to generate multiple beams by leveraging a ray-tracing-based analysis, where the resonance condition is satisfied at predefined beam angles. This approach eliminates the need for complex and bulky radiators, active elements, or mechanical adjustments, thereby simplifying the design while enhancing functionality. The antenna demonstrates simultaneous dual-beam radiation at elevation angles of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\theta_{\text {beam }, 1}=20^{\circ}$</tex> and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\theta_{\text {beam }, 2}=42^{\circ}$</tex> with a gain of 11 dBi at 27 GHz. This performance highlights the capability of the metasurface-enhanced FPC to achieve efficient beam steering without additional complexity. The findings suggest that this approach is promising for advanced communication systems requiring high-gain, multibeam radiation pattern.

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.
