1. An antenna device, comprising:
a dielectric layer comprising a separation region defined on an upper surface thereof;
a radiator on the upper surface of the dielectric layer, the radiator comprising a first mesh structure, wherein the first mesh structure includes a first antenna electrode line and a second antenna electrode line which cross each other; and
a dummy electrode spaced apart from the radiator by the separation region on the upper surface of the dielectric layer, the dummy electrode comprising a second mesh structure, wherein the second mesh structure includes a first dummy electrode line and a second dummy electrode line which cross each other,
wherein a spacing distance between the first dummy electrode line and the radiator is different from a spacing distance between the second dummy electrode line and the radiator at the separation region,
wherein the first dummy electrode line and the first antenna electrode line extend in the same direction, and a first spacing distance is defined between the first dummy electrode line and the first antenna electrode line adjacent to each other at the separation region,
wherein the second dummy electrode line and the second antenna electrode line extend in the same direction, and a second spacing distance is defined between the second dummy electrode line and the second antenna electrode line adjacent to each other at the separation region,
wherein the first spacing distance is greater than the second spacing distance.
