Abstract
The present invention relates to antennas for radio communications, and in particular although not exclusively to multiple input multiple output (MIMO) radio communications systems. An antenna arrangement comprising: a first, a second, and a third ground plane each arranged substantially perpendicular to the others; a first, a second, and a third antenna element associated with respectively said first, said second, and said third ground planes, each antenna element arranged to radiate in a predetermined polarization in elevation and azimuth with respect to said respective associated ground plane.
