Design and characterization of a miniaturized patch antenna for passive UHF RFID applications
Bibliographic record
Abstract
A low profile RFID (radio frequency identification) tag consisting of a compact microstrip patch antenna for operation at the ultra high frequency (UHF) RFID band, ranging from 860–960 MHz, is proposed. The patch is backed by a mushroom-type Electromagnetic Band Gap (EBG) structure in order to achieve an area reduction of 29.11% in comparison with a conventional patch design. The RFID chip is integrated on the patch via an inset feed line that is positioned in a way to deliver the conjugate impedance matching between the antenna and the chip. The frequency response of the assembled tag was obtained by measuring the reflected power in the ON and OFF states of the chip and subtracting them. The maximum reading range of the tag was found to be around 11 m in two test scenarios of free standing tag and tag attached on a metallic surface.

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.
