Millimeter-Wave Magneto-Electric Dipole Isolation Enhancement using Superstrate-Based Decoupler
Bibliographic record
Abstract
This work presents a superstrate-based decoupler to increase the isolation between two closely spaced Magneto-Electric (ME) dipoles in the 52–64 GHz millimeter wave (MMW) frequency band. The decoupler consists of a single row of 15 vias, and a copper plate carefully inserted into a high-permittivity superstrate between the two-element MIMO antenna. The vias help to mitigate the surface coupled waves in the antenna substrate, while the copper plate and the high-permittivity superstrate help to alter the space permittivity, disturb the space coupling, and increase the isolation. This combination improved the proposed antenna's isolation by a maximum of 31 dB over the 52–64 GHz bandwidth (14.3%) in the H-Plane, with a very close edge-to-edge spacing of 0.62 mm (0.12λ), where λ is the free-space wavelength at the center frequency of 60 GHz. Additionally, the superstrate-based decoupler structure improved the antenna's bandwidth (52–70 GHz), without distorting the radiation pattern.

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.
