Abstract
To provide an antenna assembly that forms part of an antenna module coupled to a control unit as part of a wireless communication system.SOLUTION: A wireless communication system comprises one or more cross-polarized antenna assemblies with optimized propagation delays forming part of an antenna module having two primary vertical polarizations. Isolation or crosstalk in each antenna module is minimized by implementing sectored plane isolation and a correlation enhancer, in the form of a ground plane aperture structure.SELECTED DRAWING: Figure 1
