Abstract
A compact disc ultrawideband (UWB) antenna with quintuple band rejections is proposed and demonstrated, which has a portrait shape and is therefore “portrait antenna.” The quintuple band-notched functions are achieved by utilizing C-shaped slots, nested C-shaped slots, U-shaped slots, and open-circuit stubs. It is demonstrated that the portrait antenna operating from 2.45 to 12 GHz (VSWR <; 2) has omnidirectional radiation patterns with a gain greater than 2 dBi, and also five stopbands (VSWR >; 2) of 3.27-3.57, 5.01-5.45, 5.55-6.05, 7.05-7.45 and 7.83-8.19 GHz are implemented simultaneously for rejecting WiMAX, WLAN, downlink of X-band satellite communication, and ITU 8-GHz band signals. Moreover, the antenna has a simple structure and a compact size.

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
