Sidelobe Reduction of TM<sub>12</sub>Mode of Circular Patch via Nonresonant Narrow Slot
Bibliographic record
Abstract
A technique to reduce the E-plane sidelobe of the TM12mode of circular microstrip patch is presented. It involves the use of a single nonresonant narrow slot embedded at the patch center. The fundamental working principle is the linear superposition of the radiated field by the patch and the embedded slot. The sidelobe level (SLL) and the peak gain are found to be dependent on the slot length. Effects of various design parameters like slot length, dielectric constant and substrate thickness on SLL and peak gain are investigated. Measurements results are provided to confirm these findings. In addition to this, to show the merit and utilization of the proposed technique, a novel single layer, easy to design and fabricate high gain circular microstrip antenna configuration is also proposed. It is a simple slot loaded circular patch having a peak gain ~ 11 dBi with SLL as low as -20 dB. Depending upon the substrate parameters, peak gains as large as 13 dBi can be attained.

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.
