A new RFID monopole antenna using a compact AMC structure
Bibliographic record
Abstract
Abstract A new compact artificial magnetic conductor (AMC) based coplanar waveguide (CPW) antenna is presented for RFID applications. The antenna is designed with hexagonal ring and patch elements. The proposed AMC with an electrical size of 0.02 λ 0 is designed as a reflector for a monopole antenna which improves the antenna gain from 2 to 6.7 dBi. The monopole antenna is designed using cascaded hexagonal patch and ring elements. The simulated and experimental performance of the proposed antenna are presented in terms of return loss, gain and radiation patterns, with and without the presence of AMC. The performance of the antenna is evaluated at 868 MHz (European RFID Band). The obtained results exhibit good agreement. The proposed antenna provides compactness, cost efficiency, higher gain, and higher radiation efficiency (at 868 MHz).

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.
