Abstract
An apparatus can include a substrate, a first antenna panel, a second antenna panel and a wall isolator. The first antenna panel can be coupled on the substrate and comprising an array of first antenna elements. The second antenna panel can be coupled on the substrate comprising an array of second antenna elements. The wall isolator can be coupled on the substrate. The wall isolator can include a first EBG element and a second EBG element. The first EBG element can be positioned along an edge of the first antenna panel for a length of the substrate and configured to reduce surface wave propagation from the array of first antenna elements. The second EBG element can be positioned along an edge of the second antenna panel for a length of the substrate and configured to reduce surface wave propagation from the array of second antenna elements.
