A Compact CP Wearable Antenna backed by AMC Array for WBAN/WLAN Applications
Bibliographic record
Abstract
In this paper, a simple and compact wide-slot circularly polarized antenna backed by a 2×2 artificial magnetic conductor (AMC) array is presented for 5.8 GHz wireless body area network (WBAN) applications. An inverted T-shaped parasitic strip at the open end of a microstrip line extension and slot modification was applied to attain wideband CP. The total footprint of the proposed antenna is only 30.9 × 30.9 mm2board of semi-flexible Rogers RT-Duroid 5880 substrate. Full-wave EM simulation results have been presented in numerous studies, both in free space and in proximity to the human body. The integrated design provided an impedance bandwidth |S11| ≤ -10 dB of ~9.41-percent (5.57-6.12 GHz) and an AR bandwidth ≤ 3 dB of 9.8-percent (5.24-5.78 GHz). Furthermore, over a gap of 3 mm from the human body, the final design achieved peak gain and total efficiency enhancements of 8.5 dBi and 91.4%, respectively. A very low specific absorption rate, compact size, and high gain make the proposed design a good candidate for most off-body wearable applications.

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.
