Integrated Polarization Converter for Planar Cross-Polarized Millimeter Wave Components
Bibliographic record
Abstract
In the millimeter wave (mmW) band, it is possible to excite signals in printed circuit boards or PCB where the electric field is parallel to the plane of substrate and bounded by the upper and lower conducting layers of the PCB. Based on this concept, dually polarized mmW components have been developed recently to double the capacity of those components. The integration of dually polarized and conventional single polarized components on one substrate creates a significant bottleneck. The solution for this bottleneck is the design of an integrated polarization converter which fully rotates the horizontally polarized field. This rotation converts the horizontal field to be vertical to be easily fed to the rest of the circuit with minimum loss. The polarization conversion is achieved by artificially induced skew anisotropy, which is realized by drilling tilted holes in the conventional isotropic substrate. This theoretical concept for polarization conversion is developed in this paper. The design procedures along with a simulation example are presented. Fabrication methodologies and different variations of prototypes are discussed.

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.
