1. An antenna module comprising:
a circuit board;
a radiation pattern formed on at least one surface of the circuit board and patterned in a loop shape so that an empty space part is formed at a central part thereof;
a first shielding sheet stacked on an upper surface of the circuit board so as to include a region corresponding to the empty space part, and comprising at least one crack that is formed to extend inward from an edge; and
a second shielding sheet stacked on a lower surface of the circuit board so as to include a region corresponding to the empty space part, and comprising at least one crack that is formed to extend inward from an edge,
wherein the first shielding sheet and the second shielding sheet are disposed on both surfaces of the circuit board such that areas thereof corresponding to the empty space part overlap each other,
wherein in each of the first shielding sheet and second shielding sheet, a region overlapping the radiation pattern is not formed to be separated into multiple pieces, and
wherein the at least one crack extends from the edge of each of the first shielding sheet and the second shielding sheet so as not to be formed in the region overlapping the radiation pattern.
