Gain and Bandwidth Enhancement of 2×2 Square Dense Dielectric Patch Antenna Array Using a Holey Superstrate.
Bibliographic record
Abstract
Gain enhancement and bandwidth improvement of a 2 × 2 square dense dielectric patch antenna using a holey superstrate are proposed. This aperture-coupled antenna is fed by a conventional power divider. A dielectric superstrate layer is utilized to enhance the antenna gain. Moreover, by drilling a set of identical circular holes in the superstrate layer, the antenna bandwidth is improved, and the sidelobe level is decreased. The proposed antenna is fabricated and tested. The prototype yields an impedance bandwidth of 15.35% from 26.5 to 30.8 GHz. The proposed antenna exhibits a flat measured gain of about 16 dBi over all the bandwidth with a high simulated radiation efficiency of 92%. Furthermore, the sidelobe levels of the antenna are -15.8 and -21 dB in the E-plane and H-plane, respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
