A Compact Implantable MIMO Antenna for Wireless Capsule Endoscopy
Bibliographic record
Abstract
In this paper, a compact and polarization diversity enabled implantable MIMO antenna system is developed for a 915 MHz band. The proposed antenna system comprises two elements: both radiating elements are circularly polarized (CP). Antenna-I of the suggested design works at LHCP, and the second Antenna works at right-handed CP (RHCP). Furthermore, both antennas radiate power in different directions to enable radiation pattern diversity, a key factor for non-static devices. Despite the compact size (9.01 mm3) of the proposed design, it possesses a significant isolation. The high isolation is realized using a thin substrate and slotted ground plane. Both antennas of the MIMO system possess a bandwidth of 10.5% and AR bandwidth of 10.35% at 915 MHz. Additionally, it sustains a gain of -24.6 dBiC at the resonant frequency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
