Abstract
Multiport antenna architectures that are well isolated, both within and across multiple frequency bands, not only support multiple technologies such as multiple-input--multiple-output and carrier aggregation, but also ease the design of the RF front end. In this letter, the theory of characteristic modes (TCM) is applied in a systematic manner to isolate the ports operating in the same frequency band and in different frequency bands, the latter of which is a new application of TCM. Moreover, by quantifying the amount of isolation between the multiple ports via the electromagnetic isolation method, the use of TCM as a decoupling tool for multiple antenna systems is verified. A four-port chassis-mode antenna is presented that features high levels of interband and intraband decoupling in three bands, two of which are below 1 GHz. The antenna is experimentally verified, and the measured port parameters and radiation patterns are found to match well with simulations.

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 it
