Abstract
MIMO dual-polarised antenna assembly arranged in a nested arrangement. The antenna assembly comprises a ground plane and a dual-polarised lower band antenna elements mounted to the ground plane proximal to peripheral sides of the ground plane. The location of the lower band antenna elements defines a lower band peripheral boundary. The antenna assembly comprises (1) dual-polarised upper band antenna elements mounted to the ground plane, nested within the lower band peripheral boundary, (2) an upper feeding network configured to connect opposing pairs of lower band radiating elements of the dual polarised lower band antenna elements and feed the lower band antenna elements, the upper feeding network being located within the lower band peripheral boundary, and (3) a lower feeding network positioned below the upper feeding network, and is configured to feed the dual polarised lower band antenna elements via the upper feeding network using a pair of ultra-wideband duplexers.
