1. An antenna module, comprising:
a substrate;
at least one radiating element disposed on the substrate; and
a metamaterial structure disposed on the substrate, wherein the metamaterial structure and the at least one radiating element are located on a same side of the substrate, and the metamaterial structure includes:
a metamaterial substrate having a first surface and a second surface disposed opposite to each other, wherein the second surface faces the at least one radiating element; and
a plurality of first metal conductors and a plurality of second metal conductors, wherein the first metal conductors are disposed on the first surface and spaced apart at intervals from each other, the second metal conductors are disposed on the second surface and spaced apart at intervals from each other, the first metal conductors respectively correspond to the second metal conductors, and shapes of the first metal conductors are different from shapes of the second metal conductors.
