Compact printed monopole tag antennas for UHF RFID applications
Bibliographic record
Abstract
In this paper, three compact printed monopole antennas are designed for use in UHF RFID that contain a chip with input impedance of 8.2-J61Ω. The challenges in the design of these antennas are conjugate matching of the antenna to the chip while achieving a small layout area. Inductive coupling via a printed loop is employed to eliminate the need for a matching circuit with lumped components. For each antenna, the loop area and proximity of it to the radiating body is optimized to obtain a relatively wide band (on the order of 940 MHz, from 530 MHz to 1.47 GHz) matching. Of the three designs, the proposed 3D meander monopole offers the smallest foot print and yields a 70% area reduction in comparison to a folded printed dipole that is commonly used in RFIDs.

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.
