Optically Transparent Reflectarray Antenna Design Integrated With Solar Cells
Bibliographic record
Abstract
A novel reflectarray antenna integrated with solar cells design is presented to operate in the satellite communications X-Ku band (10.7-12.7 GHz). The proposed design can be introduced as an add on feature to an existing solar cells' system ground stations. The balance between the antenna and solar cells functions is maintained using engineered optically transparent acrylic material to perform as reflectarray phase shifting as well as a transparent cover for solar cells. The design process starts by accurately modeling the solar cells effect over the radio frequency (RF) via experiments. Consequently, the reflectarray phase shifting unit cell makes use of different hole size staked perforated acrylic material incorporating the effect of the solar cells into the design. Moreover, oblique incidence analysis is rigorously incorporated into the design procedure to adequately implement the required phase shifts from the reflectarray unit cells. Furthermore, a square aperture reflectarray prototype of 11.5" side dimension is fabricated to prove the concept. The antenna provides a measured gain of 26.16 dB at 11.7 GHz. Also, the solar cells' energy harvesting is not significantly affected by the presence of the reflectarray antenna when the light source is normal to the reflectarray aperture surface.

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.
