Magneto-Electric-Dipole-Based Leaky-Wave Radiating Structure with Reduced Frequency-Dependent Beam Squint
Bibliographic record
Abstract
Frequency-induced beam squint is probably the biggest hurdle in some cases that limits the application of leaky-wave antennas (LWAs) and leaky-wave radiating structures (LWRSs) to communication systems. In this paper, we derive a frequency-phase condition of guided-wave radiation elements in an LWA or LWRS to prevent beam squint from frequency scanning. It is found out that magneto-electric (ME) dipoles can be used as radiation elements which possess the required frequency-phase condition in a considerable wide band. Over this band of interest, the main lobe direction of the obtained LWA or LWRS based on the ME dipole can be constant. A simulated LWA prototype demonstrates its beam is fixed at -14° from 16.9 GHz to 17.9 GHz with a well suppressed effect of beam squint over the operation band.

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.
