Abstract
This study presents an ultraminiaturized implantable in-band full-duplex (IBFD) antenna, designed for wireless capsule endoscopy (WCE) applications. Through the integration of semicircular slots and shorting pins, the antenna achieves a small volume of 7.17 mm3 (<inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\pi \times $ </tex-math></inline-formula> (3 mm)<inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{2} \times 0.254$ </tex-math></inline-formula> mm), surpassing the state-of-the-art in compactness. Simulations of the proposed design are conducted within a human body phantom to demonstrate the antenna’s operation at 2.45 GHz. Radiation patterns from both ports are nearly omnidirectional, and an isolation level of greater than 28 dB is achieved. Our results indicate that the antenna can establish reliable wireless communication over distances exceeding 8 m, with a 10-dB margin at both ports. The specific absorption rate (SAR) values at 2.45 GHz are found to be 29.7 W/kg at 1 W input power. Experimental validation using minced pork demonstrated a good agreement with simulation results.

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
