FPC Antennas: C-band point-to-point communication systems
Bibliographic record
Abstract
A high-gain wide-band Fabry-Perot cavity (FPC) antenna is presented for C-band point-to-point communication systems. The proposed antenna utilizes a broadband aperture-coupled microstrip antenna (ACMA) as the source and multilayer frequency-selective surfaces (FSSs) as the superstrate. The experimental result shows that the proposed antenna achieves an impedance band from 4 to 5.4 GHz (30%) for ${\rm S}_{{\rm 11}}{\rm \leq-10}$ dB. The wide band is obtained through the merging of different resonance frequencies due to the patch, the coupling aperture, and the superstrate layer. The antenna also facilitates an enhanced broadside gain up to 14.2 dBi at 4.8 GHz with variations of less than 4 dB throughout the operating band by loading three layers of FSS superstrate. Furthermore, a parametric study is performed to provide antenna engineers with information about the design.

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.
