Abstract
An apparatus includes a substrate, a first antenna panel, a second antenna panel, and an antenna isolator. The first antenna panel is coupled on the substrate and includes an array of first antenna elements. The second antenna panel is coupled on the substrate and includes an array of second antenna elements. The antenna isolator is coupled on the substrate and including a plurality of walls extending outwardly from the substrate along a length of the substrate between the first antenna panel and the second antenna panel. The antenna isolator reduces reduce wave propagation between the array of first antenna elements and the array of second antenna elements.
