  • Abstract
    Superdirectivity has been a controversial idea to increase the resolving power of an antenna aperture and hence increase the number of spatial degrees of freedom. In this paper, we take into account both radiated power and reactive power, and show that superdirectivity does not have a drastic impact on the total number of spatial-temporal degrees of freedom in wireless channels.
