Design of an UWB antenna with WLAN band notch characteristic
Bibliographic record
Abstract
This paper presents an Ultra-Wideband miniaturized antenna with WLAN band notch characteristics, measuring only 22 mm×13 mm×0.8 mm, and achieves UWB operating characteristics of 4.12-18 GHz through optimization of the M-shaped multi-branch coupling slot structure. At 4.52 GHz, 9.68 GHz and 13.16 GHz, the S11 achieves excellent impedance matching performance of -28.5 dB, -37.88 dB and -24.4 dB respectively. Its wideband characteristics can be applied to satellite communications (C-band, 4-8 GHz) and military radar systems (X-band, 8-12 GHz) and space radio communication (Ku band, 12-18 GHz) and other fields. With a specially designed notch function, the antenna achieves active signal suppression in the 5.8 GHz (5.030-5.835 GHz) band where the WLAN operates, effectively avoiding co-frequency interference with the WLAN system. This antenna demonstrates its unique application value in multi-band integrated systems and electromagnetic compatibility scenarios, as well as in scenarios such as IoT devices, medical electronics, avionics systems, satellite relay communication systems, and military equipment that requires covert communication, which need to operate independently in complex electromagnetic environments.

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.
