Abstract
The pursuit of wireless spectral efficiency draws on many different research areas. The area of largest potential impact is the deployment of multiport antennas. This is because it is the only technology that allows simultaneous sharing of the spectrum between many users, including full duplex operation in some circumstances. The spectral efficiencies of current communications system designs are still a long way from their information-theoretic limits, and similarly, current multi-element antenna designs seem to fall short of compactness limits. This invited paper, in tutorial style, touches on how wireless has reached this point, and the need to address grand challenges in information theory, communications techniques, networking, antenna elements and arrays, and signal theory. These aspects converge to set the scene for a new generation of adaptive antenna technology. The motivation is from basic energy and communications considerations. The design of compact multiport antennas requires an extension of classical performance metrics and new approaches to measurement and evaluation. Tools such as physics-based statistical channel and circuit models are likely to play a future role in the design of large-scale multiport 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.
