Millimeter-Wave ME-Dipole Array Antenna Decoupling Using a Novel Metasurface Structure
Bibliographic record
Abstract
A novel customized π-shaped split-ring resonator metasurface arranged in two configurations is presented to decouple 1×2 and 1×4 Millimeter-Wave (MMW) Magneto-Electric (ME) Dipole in the H-Plane with 1.6 mm (0.32λ at 60 GHz) inter-element spacing. The metamaterial unit cell is first designed to inhibit the propagation of coupled surface waves within the bandwidth of interest. A 5×2 arrangement of this unit cell is carefully positioned on the top and bottom of the superstrate with 1 mm spacing (0.2λ at 60 GHz) between the antenna and the superstrate. In the 1×2 array, a maximum measured mutual coupling reduction of 53 dB is observed within the 52-66 GHz bandwidth (23.7%). To further demonstrate the uniqueness of the metasurface, an 11×2 configuration of this unit cell is arranged as a superstrate for the 1×4 ME-dipoles. A maximum measured mutual coupling reduction of 40 dB is achieved without a considerable effect on the radiation characteristics. Parametric analysis is performed to confirm the uniqueness of this new decoupling structure. The proposed antenna exhibits measured high total efficiency (> 89%), high gain (> 8 dB), low envelope correlation coefficient (<0.0003), and very good radiation characteristics throughout the entire bandwidth. The fabricated prototype antenna is measured to validate the simulation results. The proposed antenna is a good recommendation for V-band millimeter-wave MIMO applications like radar research.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
