Wideband planar Goubau line integrated circuit components at millimetre waves
Bibliographic record
Abstract
This study provides the design, fabrication and test results of passive planar Goubau line (PGL) components compatible with active micro-strip circuits, in millimeter(mm)-wave frequency range (40–60 GHz). Such wideband passive components are of interest in designing wideband digital wireless communication equipment. Basic passive components of this study include: two PGLs with conductor strip widths of 50 and 260 µm, respectively, transitions from chosen PGLs to 50 Ω micro-strip circuit, PGL loads and PGL power divider/combiners. Active components such as planar micro-strip circuits can be placed in tandem with passive PGLs using above transitions to design wide band circuits from microwaves to mm waves. PGL is formed by a planar conductor deposited on a standard 0.254 mm (10 mil) planar alumina substrate (ceramic) as opposed to the standard Goubau line made with a circular conductor and a circular dielectric. Passive PGL components are designed, simulated, fabricated and measured with an automatic network analyser (ANA) and test fixture. Simulation and test data support PGL component designs. PGL components operate well over a wide frequency range (from 40 to about 60 GHz). Similar results are expected with PGL at other mm-wave frequencies (below 40 GHz and above 60 GHz) and at terahertz frequencies (above 100 GHz).

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.
