Abstract
Ultra-wideband (UWB) short-range communication systems are valuable in medical technology, particularly for implanted devices, due to their low-power consumption, low cost, and high data rates. Several emerging medical applications require that a miniature data acquisition device be implanted in the head to extract and wirelessly communicate brain activity to other devices. In such applications the antennas, a key component in a wireless implanted device, require extreme biocompatibility and limited size. This paper presents the design of a miniaturized UWB monopole microstrip antenna that is electrically suitable for implantation in the human head. The antenna is fed by a microstrip line on an FR4 substrate, has a size limited to 12mm×12mm, and is optimized against the effects of biological tissues. Optimization is performed numerically with HFSS. The return loss, radiation pattern and specific absorption rate (SAR) performance of the antenna are simulated and compared for three antenna sizes. Based on these results, a suitable UWB antenna is proposed for operation in an implanted neural recording device.

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
