Patent ID: 11532898

Abstract:
Multiband multiple input multiple output (MIMO) dual polarised antenna assembly (100) comprising: dual polarised lower band antenna elements (10,20) mounted to ground plane (50) and located proximal to ground plane peripheral sides (50), the location of the lower band antenna elements (10, 20) defining lower band peripheral boundary; dual polarised upper band antenna elements (200, 210) mounted to ground plane (50) and nested within the lower band peripheral boundary; upper feeding network (130) connecting opposing pairs of lower band radiating elements (11, 12, 21, 22) of the dual polarised lower band antenna elements (10,20) and feeds the lower band antenna elements (11, 12, 21, 22), the upper feeding network (130) located within the lower band peripheral boundary; and lower feeding network (140) positioned below upper feeding network (130) and feeds the dual polarised upper band antenna elements (10, 20) via upper feeding network using pair of ultra-wideband duplexers (20A, 20B).
