Packaged Microstrip Line Feed Network on a Single Surface for Dual-Polarized 2<sup>N</sup>×2<sup>M</sup> ME-Dipole Antenna Array
Bibliographic record
Abstract
A packaged microstrip line feed network on a single substrate surface is presented in the Ka-band for a 4 × 4 dual-polarized array with a capability to be expanded to higher order 2N× 2M, where N and M are integer numbers larger than 1. A dual-polarized aperture-coupled magneto-electric dipole antenna is designed as a single element with 20% bandwidth of -10 dB reflection coefficients, ports' isolation better than 35 dB, cross polarization less than -25 dB within the main beam view-range of 30°, and gain of 8 dBi. A 4 × 4 array is implemented that maintains a bandwidth of 16.7% at 30 GHz with a maximum gain of 19.3 dBi.
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.
