1. A radio frequency device, including:
a substrate;
a first radiating element;
a second radiating element;
a first transmission line on a first major surface of the substrate, the first transmission line coupled to the first radiating element;
a second transmission line adjacent to the first transmission line and on the first major surface of the substrate, the second transmission line coupled to the second radiating element; and
a metasurface decoupling element printed on the first major surface of the substrate, where the metasurface decoupling element is arranged between the first transmission line and the second transmission line.
