Compact and Broadband Transition of Microstrip Line to Finite-Ground Coplanar Waveguide
Bibliographic record
Abstract
In this paper, a compact and broadband transition of microstrip line to finite-ground coplanar waveguide (FGCPW) is proposed. Design rules are presented on the basis of simulation and measurement results. Both electric and magnetic fields are gradually transformed from microstrip line to FGCPW by tapering the signal conductor. The microstrip ground plane on the bottom side of the substrate is directly connected to the grounds of the FGCPW on the top side with metallic vias, providing an RF short-circuit for suppressing parasitic modes. Measured return loss is lower than -10 dB for a back-to-back structure from 0.04 GHz to 24 GHz with a low insertion loss of about 1.5 dB at 20 GHz. This kind of transition can find applications in highly integrated circuits and systems using both FGCPW and microstrip line techniques, and also offer easy and accurate measurements of FGCPW circuits with the help of simple coaxial adapters.

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.
