V‐band millimeter‐wave microstrip to rectangular waveguide transition
Bibliographic record
Abstract
Abstract This article proposes a novel millimeter‐wave microstrip (MSL) to WR 12 standard rectangular waveguide transitions. These dissimilar structures are interconnected via a substrate integrated waveguide (SIW). The MSL and the SIW are integrated on the same ceramic substrate of 9.9 relative permittivity and 125 μm thickness. The MSL was first transformed into an air‐filled rectangular waveguide, and then a stepped impedance or horn transformer was used to match the WR12 standard rectangular waveguide. The central frequency of operation is 61 GHz as required in V‐band wireless communications applications. Commercial Finite Element Method Software and High Frequency Structure Simulator (HFSS) was used to perform the design and the optimization. The S parameter measurements of the back‐to‐back connected transitions show an insertion loss less than 1.5 dB and a return loss better than −10 dB over a 4 GHz band from 60 to 64 GHz. The high performance, the compact size, and the simple fabrication, enable similar transitions to be employed in a number of other millimeter‐wave applications. © 2013 Wiley Periodicals, Inc.

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.
