Corrugated SIW L-folded antipodal parabolic tapered slot antenna
Bibliographic record
Abstract
In this paper, corrugated SIW L-folded antipodal parabolic Tapered Slot Antenna (TSA) is proposed and demonstrated for the very first time. Compared to other reported SIW TSA, this design achieves foot-print reduction by a factor of nearly two and excellent radiation pattern symmetry. This structure can easily be designed to obtain either 45° or -45° polarization. Moreover, this single element shows advantages over other reported end-fire TSA for arrays, namely, it can achieve a lower spacing between elements to obtain reduced side-lobe level (SLL) and 45° or -45° polarizations as well as reduced coupling between adjacent elements. To feed this antenna, an L-Folded SIW (LFSIW) line is introduced. An L-junction from SIW to LFSIW is also proposed and studied. The gain of single L-folded element is 13 dBi compared to 15.1 dBi for the unfolded antenna. However, the folded antenna provides an 8.5 dB improvement in the coupling level between adjacent elements.

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; both teacher heads agree on what is shown here.
