An SICL-Fed Compact Magnetoelectric Dipole Antenna for 5G Millimeter Wave Bands
Bibliographic record
Abstract
A compact magnetoelectric (ME) dipole antenna element is proposed for design of wide beam steering arrays in the 5G millimeter wave (mm-wave) bands n257, n258 and n261. The antenna employs an substrate integrated coaxial line (SICL) based feed. The SICL line is transformed into a coplanar waveguide (CPW) to enable feed for ME dipole antenna. With adoption of a U-shaped shorting strip and SICL-CPW-based feed, the element achieves an -10 dB impedance bandwidth (IBW) of 22.4% at the center frequency (f0) of 26.8 GHz. Notably, the antenna offers ~ 100° of 3 dB beamwidth and a compact size of 0.32Ao x 0.32Ao, where Ao is free space wavelength at f0. Using full-wave simulations, an 8-element uniform linear array (ULA) is shown to exhibit fractional IBW of 19%, max gain > 15 dBi with large beam steering angles up to 56°. The antenna can be easily fabricated using standard four layer printed circuit board (PCB) technology on Rogers 5880 dielectric laminates.

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.
