Abstract
Defected Ground Structure (DGS) is relatively a new area of research and applications associated with printed circuits and antennas. This chapter addresses the fundamentals of the DGS from its evolution and modeling to the state-of-the-art applications. The DGS geometries reported so far include simple shapes such as rectangular dumbbell, circular dumbbell, spiral, "U", "V", "H, cross, concentric rings, etc. Also different complex structures like split ring resonators, or fractals have been examined. To stop the higher harmonics at the input of the microstrip element, proper bandstop characteristics in the feeding network have been explored using different DGS configurations. The DGS has been implemented to improve or modify the radiation properties of microstrip patches. Placing the DGS in between the two microstrip patches also has some useful applications in reducing mutual coupling between them.

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 it
