Abstract

An antenna device according to an embodiment may include a dielectric layer, a radiator and a transmission line which are disposed on an upper surface of the dielectric layer and formed in a mesh structure. A mesh line width of the transmission line may be thicker than a mesh line width of the radiator.

First claim

What is claimed is:

1. An antenna device comprising:
a dielectric layer; and
a radiator and a transmission line which are disposed on an upper surface of the dielectric layer and formed in a mesh structure,
wherein a mesh line width of the transmission line is thicker than a mesh line width of the radiator,
wherein the mesh line width of the transmission line is from 3.0 μm to 7.0 μm, and the mesh line width of the transmission line is smaller than a value obtained by multiplying the mesh line width of the radiator by 2.6.

2. The antenna device according to claim 1 , wherein the mesh line width of the transmission line is smaller than a value obtained by multiplying the mesh line width of the radiator by 2.2.

3. The antenna device according to claim 1 , wherein an area of the transmission line is a value or less obtained by multiplying a reference area by 0.1,
wherein the reference area is calculated by multiplying a sum of a length of the radiator and a length of the transmission line by a width of the radiator.

4. The antenna device according to claim 1 , further comprising a ground layer disposed on a lower surface of the dielectric layer.

5. The antenna device according to claim 1 , further comprising a signal pad connected to an end of the transmission line.

6. The antenna device according to claim 5 , further comprising a ground pad disposed around the signal pad to be separated from the signal pad.

7. The antenna device according to claim 6 , wherein the signal pad or the ground pad has a solid structure.

8. The antenna device according to claim 1 , further comprising a dummy pattern disposed on an upper surface of the dielectric layer.

9. The antenna device according to claim 8 , wherein the dummy pattern is arranged around the radiator and the transmission line.

10. The antenna device according to claim 8 , wherein the dummy pattern is formed in a mesh structure.

11. The antenna device according to claim 10 , wherein the mesh line width of the dummy pattern is the same as the mesh line width of the radiator.

12. The antenna device according to claim 8 , wherein the dummy pattern is electrically separated from the radiator and the transmission line.

13. A display device comprising the antenna device according to claim 1 .
