Dual-Polarized Cosecant-Squared Beam-Shaped Array Antenna for mmWave Mobile Communications
Bibliographic record
Abstract
Mobile communication in the millimeter-wave (mmWave) band offers high data rates but requires complex, power-intensive beamforming systems. This paper presents a cost-effective cosecant-squared ($csc^{2}$) beam-shaped array antenna designed to reduce beamforming complexity and power consumption for base station applications. A compact, dual-polarized waveguide array antenna is developed operating between 37 GHz and 42 GHz. The$csc^{2}$radiation pattern is achieved by optimizing both amplitude and phase weights. Amplitude weights are generated using a dual-mode unequal ratio power splitter, while phase weights are obtained through dielectric rod loading. This ensures uniform power distribution to all users, regardless of distance from the base station. A Rotman lens is also incorporated for azimuth beam steering. The prototype is fabricated with 3D printing and PCB technologies and has been tested for beam-shaping and beam-forming performance.

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.
