Analysis of Spherical Multiple-Input Multiple-Output Antenna

Kontakt: Čapek Miloslav – miloslav.capek(z)

Dislocate a given number of half-wavelength dipoles along a hypothetical spherical surface in such a way that the capacity is maximized. The optimal placement is given by the point group theory predicting that the group generators give the placement and the character letters determine the excitation. Derive the optimal positions and the feeding scenarios analytically and utilize them in numerical verification. For numerical solution, utilize alternatively method of moments evaluation with decomposition into so-called energy modes and their water filling equalization. To check the final solution, investigate capacity of some placement/feeding perturbations (should yield lower capacity).
