1. An antenna device, comprising:
a dielectric layer;
a radiation pattern disposed on a top surface of the dielectric layer;
a signal pad electrically connected to the radiation pattern; and
a ground pad spaced apart from the signal pad and having an isolation space, wherein a length of the isolation space is greater than a length of the signal pad,
wherein the length of the isolation space is 2 to 300 times the length of the signal pad,
wherein the ground pad comprises:
a pair of protruding bars extending in a length direction of the antenna device and facing each other in a width direction of the antenna device; and
a connection bar extending in the width direction and connecting the protruding bars.
