Abstract

The present invention is directed towards a Multiple-Input Multiple-Output (MIMO) omnidirectional antenna. The Multiple-Input Multiple-Output (MIMO) omnidirectional antenna comprising three or more column sets, where the three or more column sets are arranged in a centrosymmetric arrangement about a centre point of the antenna. Each column set comprises two or more antenna columns and each of the antenna columns mounts a plurality of radiators thereon. Each antenna column receives no more than two signals to be transmitted, and, each of the antenna columns is arranged to be axisymmetric about a radially-directed axis created between the centre point of the antenna and a transverse cross-sectional midpoint on the antenna column. Therefore, each radiation pattern established by each of the three or more column sets is centrosymmetric about the centre point of the antenna, and, is axisymmetric about the radially-directed axis. This is advantageous as the MIMO omnidirectional antenna can fit within a radome of relatively small diameter, whilst the radiation plot coverage provided by the MIMO omnidirectional antenna will be relatively uniform across a microcell where the MIMO omnidirectional antenna is deployed. Moreover, as no phase shifting is utilised, there will be little ripple effect on the radiation plot coverage and all of the ports of the MIMO omnidirectional antenna will have a substantially similar gain.
