Wide‐b‐and circularly polarised slot antenna by using artificial transmission line
Bibliographic record
Abstract
A novel single‐feed wide band planar single layer circularly polarised (CP) slot antenna is presented. This low cost slot antenna consists of an L‐shaped feeding stub with metamaterial inspired complementary split ring resonator (MICSRR) and a wide 45° rotated symmetric square aperture. Broadband impedance and CP radiation bandwidth (BW) is achieved by using a novel artificial exciting stub with defecting CSRRs on it. By controlling the excitation phase of L‐shaped stub, a desirable circular polarisation can be generated and both impedance and CP BWs are considerably increased by up to 89%. The operating frequency ranges in S/C band about 1.5 octaves from 2.4–6.22GHz that covers most of the commercial wireless communication systems, such as WLAN (IEEE 802.11 (2.4/3.6/4.9/5/5.9GHz)), LTE and WiMAX (2.5/3.5/5.8GHz). The measured BWs of 3‐dB axial ratio and voltage standing wave ratio < 2 are around 91% (2.4–6.4GHz) and 89% (2.4–6.22GHz), respectively. The measured boresight gain is less than 6 dBic over the CP BW.

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.
