Ultra-Wideband Microstrip to Substrate Integrated Waveguide (SIW) Vertical Transition
Bibliographic record
Abstract
an ultra-wideband vertical microstrip to substrate integrated waveguide (SIW) transitions is proposed for Three-dimensional (3-D) densification. The corner formed by the two different transmissions lines and electrical walls can easily transform the E-field of the dominant mode in the microstrip line to the SIW mode. An equivalent model based on the lumped element is proposed to estimate the initial parameters and to study the performances of the structure. Based on this model, two configurations are built. In the first configuration, the SIW line is on the same side of the microstrip line (MSL) and in the second one, it is integrated into the side of the ground plane. For experimental validation, two back-to-back prototypes MSL-SIW-MSL transitions are fabricated, with a SIW line acting as a bridge. The measured results agree well with those in the simulations, showing a return loss better than 10 dB over the entire 22 - 50 GHz frequency range with a maximum insertion loss of 1.8 dB.

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.
