1. An antenna module comprising:
a dielectric substrate;
a first layer arranged on a front surface of the dielectric substrate, and comprising a radiator region having a first metal mesh grid and a dummy region having a dummy mesh grid comprising a plurality of patterns; and
a second layer arranged on a rear surface of the dielectric substrate and configured to allow a second metal mesh grid to operate as a ground,
wherein the plurality of patterns constitute a first metal line to a fourth metal line, the first metal line and the third metal line are lines parallel to each other, the second metal line connects the first metal line to a first end portion of the third metal line, and the fourth metal line is connected to a second end portion of the third metal line, and
side surface radiation at the first layer is prevented by a capacitive component between the plurality of patterns of the dummy mesh grid on the first layer and the second metal mesh grid on the second layer and an inductive component of the second metal mesh grid on the second layer.
