On the Spectral Efficiency of a Sphere

By Mats Gustafsson and Sven Nordebo
Progress In Electromagnetics Research, Vol. 67, 275-296, 2007


In many cases it is desired to have both high capacity and small antennas in wireless communication systems. Unfortunately, the antenna performance deteriorates when the antennas get electrically small. In this paper, fundamental limitations from antenna theory and broadband matchingare used to analyze fundamental limitations on the spectral efficiency of an arbitrary antenna inserted inside a sphere.
