Frequency notched balanced antipodal tapered slot antenna with very low cross‐polarised radiation
Bibliographic record
Abstract
The authors present the design and realisation of balanced antipodal tapered slot antenna (BATSA) with frequency notched ultra‐wideband impedance characteristics, very high gain and extremely low cross‐polarised radiation. The proposed antenna comprises a central elliptic conductor sandwiched between two elliptic conductors etched on two dielectric substrates both of which acts as the ground planes and thereby provide an electromagnetic balance for the radiating electric field. The proposed BATSA is fed by a microstrip line. The microstrip section is followed by the radiating flared section of the antenna. The notch frequency is achieved by introducing a quarter wavelength spur line in the feeding microstrip line of the antenna. The fabricated prototype of the antenna was characterised for impedance and radiation performance revealing a very good correspondence with simulation results. Radiation pattern characterisation confirms high gain in the end‐fire direction and very low cross‐polarisation compared to antipodal tapered slot antenna.

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.
