Dual-band millimeter-wave interleaved antenna array exploiting low-cost PCB technology for high speed 5G communication
Bibliographic record
Abstract
In this paper, a novel dual-band co-aperture antenna array with high bandwidth is presented. The proposed frequency bands of interest are E-band and LMDS which can work simultaneously in a dual-band mm-wave radio to achieve high throughput. The distribution network is based on the combination of Substrate-Integrated-Waveguide (SIW) and stripline technologies. These feed networks co-exist in a low-cost PCB with 4 metal layers with minimal interference. The SIW distribution network feeds slot apertures with a special offset from the center axis of the waveguides, while the stripline lines excite U-shaped patch antennas by vertical vias. A 4×4 dual-band E-band/LMDS array prototype is presented to validate the concept. The dual-band antenna array is approximately 12mm×12mm in size realized on a Rogers 4350 substrate. Measured results versus simulations have been presented and discussed. This dual-band technique can be a great candidate for the multi-Giga-bit/s (Gbps) cellular applications for 5G communication and is compatible with low cost multilayer technologies.

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.
