Cavity-excited Ferroelectric Lens Antenna for Low-Sidelobe Beam Steering
Bibliographic record
Abstract
Utilizing the technique of cavity excitation, this paper proposes a novel beam steering antenna with low sidelobe level. The whole beam steering antenna consists of two parts, i.e., a parallel plate waveguide based ferroelectric lens and a cavity-type feeding source. By independently tuning the DC bias voltage of each column of the ferroelectric lens, the beam of feeding source can be effectively collimated and steered in the far-field. By eliminating the spillover radiation at lens edge, low-sidelobe beam steering can be implemented. Full-wave simulated results show that the proposed antenna can achieve sidelobe levels of -34 dB at 0° steering angle and -25 dB at 30° steering angle. Without involving the complex feeding networks, the proposed lens antenna provides a promising alternative of complicated phased array antennas.

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.
