Cross‐slot coupled elliptical patch antenna circularly polarized for localization
Bibliographic record
Abstract
Abstract This paper reports a circularly polarized cross‐slot coupled elliptical patch antenna for implementation in a new radio‐frequency identification and localization system currently under development. The radio‐frequency localization system in this work is composed of a reader and a semiactive tag (a battery feeds the tag to increase its reading range but the backscattering modulation principle is used to decrease its power consumption). The overall system is designed in the ISM frequency band of 5.8 GHz. This frequency band is a good compromise that permits a large bandwidth and a good range for use in a local positioning system (∼10 m). This antenna is to be used by the reader as its radiation pattern is semispherical. It provides the circular polarization required by the targeted application to allow the tag identification within any physical position. The antenna bandwidth and axial ratio were enhanced using a proper design and a cross‐slot feeding of the patch. © 2006 Wiley Periodicals, Inc.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
