This paper introduces a theory for assessing and optimizing the multiple-input-multiple-output performance of multi-port cluster antennas in terms of efficiency, channel correlation, and power distribution. A method based on a convex optimization of feeding coefficients is extended with additional constraints allowing the user to control a ratio be...

... the trade-off between total efficiency η and envelope correlation coefficient E 12 , the power ratio sweep is extended to β 12 , γ 12 ∈ [−0.5, 0.5], see Fig. 5, and problem (18) is solved at f = 735 MHz with κ 12 = 10. Total efficiency is depicted as a contour plot and envelope correlation is shown with ellipses of constant E 12 , see Appendix C. The figure also shows that not all combinations of power ratios lead to a feasible solution. The unfeasible solutions are bounded by a maximal ...
