Abstract: An antenna device according to an embodiment of the present invention includes a dielectric layer, a radiator and a dummy electrode. The radiator is disposed on the upper surface of the dielectric layer. The radiator includes a first mesh structure, and the first mesh structure includes a first antenna electrode line and a second antenna electrode line which cross each other. The dummy electrode is spaced apart from the radiator by the separation region on the upper surface of the dielectric layer. The dummy electrode includes a second mesh structure, and the second mesh structure includes a first dummy electrode line and a second dummy electrode line which cross each other. 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.

Abstract: An antenna structure includes a dielectric layer, a radiation pattern on the dielectric layer and a signal pad on the dielectric layer. The signal pad includes a bonding region that is electrically connected to the radiation pattern and is configured to be bonded to an external circuit structure, and a margin region adjacent to the bonding region. Impedance mismatching is prevented by the margin region so that radiation efficiency is improved.
