1. An antenna assembly comprising:
- a substrate having a ground plane comprised of a conductive material;
a first antenna element mounted to the substrate and coupled to the ground plane;
a second antenna element mounted to the substrate and coupled to the ground plane;
a third antenna element mounted to the substrate and coupled to the ground plane; and
a plurality of features etched into the ground plane, each of the features having a respective length and a respective width;
wherein the respective length and the respective width of the features are selected to increase isolation between the first, second, and third antenna elements;
wherein at least one of the first, second, or third antenna elements includes an antenna portion that is mounted to the substrate and oriented perpendicular to the substrate, the antenna portion having an enclosed slot in which a perimeter of the enclosed slot is entirely within the antenna portion.
