Abstract
A novel high-gain circular microstrip radiator is proposed. The antenna consists of two circular discs, in a stacked configuration, designed to operate in TM11and TM13modes. The patches are designed, so that the resonant frequencies for both modes converge into a single frequency. It is found that by simultaneous excitation of both resonant modes, high gain and low sidelobe level (SLL) can be obtained in the radiation patterns. Excitation is done using a single coaxial feed. The fundamental working principle of the antenna is based on the superposition of radiated far fields of the TM11and TM13modes. At first, through a pattern synthesis, using different far field mode amplitude ratios, it is shown that the substrate dielectric constants can be selected for both layers such that it leads to low SLL. Next, for practical antenna design, the mode excitation, input impedance, and radiation properties of the TM13mode are studied. For sound understanding and explanation, the edge voltage ratio at the aperture and mode amplitude ratio in the far field are calculated and their effects on SLL and peak directivity are discussed. Finally, the measurements results are provided in support of simulations.

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.
