US 2019/0348769 A1 · MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) OMNIDIRECTIONAL ANTENNA

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.

Dependent claims

A 4×4 Multiple-Input Multiple-Output omnidirectional antenna comprising a plurality of radiators mounted on six antenna columns, with each of the six antenna columns mounting a plurality of radiators;

each of the six antenna columns being substantially rectangular in shape such as to comprise side edges, a top edge and a bottom edge whereby the side edges are longer than the top and bottom edges;
each of the six antenna columns being positioned adjacent to two of the remaining antenna columns along its side edges, such that the six antenna columns are arranged to have a substantially hexagonal transverse cross-section.

An 8×8 Multiple-Input Multiple-Output omnidirectional antenna comprising a plurality of radiators mounted on twelve antenna columns, with each of the twelve antenna columns mounting a plurality of radiators;

each of the twelve antenna columns being substantially rectangular in shape such as to comprise side edges, a top edge and a bottom edge whereby the side edges are longer than the top and bottom edges;
each of the twelve antenna columns being positioned adjacent to two of the remaining antenna columns along its side edges, such that the twelve antenna columns are arranged to have a substantially dodecagonal transverse cross-section.
