Multi-port Slot Array Antenna for Millimeter-wave Direction Finding and Beam-forming Applications
Bibliographic record
Abstract
A simple multi-port antenna structure is proposed which can be used for direction finding (DF) and beam-forming applications in the receive and transmit modes, respectively. The proposed antenna offers unique functionalities in both receive and transmit modes. For DF applications in the receive mode, the beam-scanning laws of each antenna array is engineered to cover a given sector of space and the back-end of the system will feature a power sensing mechanism to monitor the power received at all ports. In the transmit mode, the proposed antenna can be used for beam-forming applications by engineering the individual port excitation and the antenna sub-arrays. The proposed antenna structure characteristics are demonstrated using full-wave simulations at 58-61 GHz based on circularly polarized slot arrays using substrate integrated waveguide (SIW) technology. Initial results show the antenna features high angle of arrival (AoA) resolution and a wide sector coverage, making it a good candidate for 5G wireless systems.

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.
