Dual Complementary Source Magneto-Electric Dipole Antenna Loaded With Split Ring Resonators
Bibliographic record
Abstract
In this paper, a magneto-electric (ME) dipole antenna excited by two slots through a printed ridge gap waveguide (PRGW) is presented. This antenna, which operates in the Ka-band, is considered as a dual complementary source (DCS), and exhibits a higher gain and a wider impedance bandwidth, compared to conventional ME dipoles. The proposed antenna has an impedance matching bandwidth with |S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> | <; -10 dB from 24.5 to 40 GHz with a stable gain of 10±1 dBi over the 25-35 GHz band. Moreover, by integrating horizontally three layers, each with an array of 4 × 10 split-ring resonator (SRR) unit cells on top of the DCS-ME dipole antenna, the realized gain is increased while maintaining the impedance bandwidth of the antenna. The antenna was fabricated and measured to confirm the simulation results. The fabricated prototype has a size of 1.1 × 1 × 0.58 λ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> (at 30 GHz) and exhibits a measured impedance bandwidth in excess of 50%, from 24 to 40 GHz, a maximum measured gain of 14.2 dBi at 35 GHz, and a measured radiation efficiency of 93% at 30 GHz.

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.
