Compact Circularly Polarized Wideband Wearable Slot Antenna for WBAN/WLAN Applications
Bibliographic record
Abstract
In this paper, a new compact single-layer circularly polarized (CP) slot antenna useful for wearable applications is proposed. The overall size of the antenna is 34.9mm×34.9mm× 0.64mm which is almost 0.23λ0× 0.23λ0× 0.004λ0at the lowest frequency of the operating bandwidth. The antenna 10-dB impedance bandwidth of 33.6% (2.03 - 2.85 GHz), and 3-dB axial ratio bandwidth of 22% (2.34 - 2.92 GHz), make the antenna a good candidate for wireless body area network (WBAN) and wireless local area network (WLAN) applications. The antenna is co-planar waveguide (CPW)-fed, with a rectangular slot on the top, and four rectangular strips at the bottom sides of the substrate, to improve the performance of the antenna in terms of axial ratio. The maximum right handed circular polarization (RHCP) gain of the antenna is 3.2 dBic, occurring at 2.4 GHz and boresight.

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.
