Coplanar waveguide‐fed rose‐curve shape UWB monopole antenna with dual‐notch characteristics
Bibliographic record
Abstract
In this study, a new design of a planar ultra‐wideband (UWB) monopole antenna with a rose‐curve contour shape is proposed. The rose‐curve circumference of the monopole is expressed in polar coordinates as: . This function enables a flexible and easy to control layout, which directly affects the antenna's response. The arguments of the function are specified based on a simple deterministic design rule and the outputs of a parametric study. The antenna covers the 3.1–11 GHz band and has an ultra‐miniaturised size of 864 mm 3 when realised on a RT/Duroid 6010LM substrate of 0.635 mm thickness. To add dual‐notch characteristics to the proposed antenna, a complementary dual‐band split ring resonator inclusion is etched on the antenna's patch near the feeding line. The inclusion is designed to operate at the two Wi‐Fi and ISM frequency bands, 3.5 and 5.8 GHz, respectively. These centre band frequencies are determined using a new hybrid method that utilises the resonant and non‐resonant design approaches of metamaterial structures. Simulated and measured return loss values, radiation patterns and gain values for the proposed antennas (with and without notching) are in very good agreements, and demonstrate satisfactory performance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
