Embodiment approach

[0036] According to an exemplary embodiment of the present invention, there is also provided a display device including the antenna device. Applications of the antenna device are not limited to display devices, and the antenna device may be applied to various objects or structures such as vehicles, home appliances, buildings, and the like.

[0037] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, those skilled in the art will appreciate that such embodiments described with reference to the accompanying drawings are provided for further understanding of the spirit of the present invention and do not limit the subject matter to be protected as disclosed in the detailed description and the appended claims.

[0038] figure 1 with figure 2 are a schematic cross-sectional view and a schematic top plan view showing an antenna device according to an exemplary embodiment, respectively.

[0039] refer to figure 1 w...

Embodiment 1

[0094] On the top surface of the glass dielectric layer (0.7T), an alloy (APC) of silver (Ag), palladium (Pd), and copper (Cu) is used to form radiation patterns and transmission lines having a grid structure. The wires included in the mesh structure are formed to have a line width of 2.5 μm and The thickness (or height) of , and the grid structure is formed with rhombus-shaped unit cells. The length of the X-axis diagonal (short diagonal) of the diamond-shaped unit cell is 150 μm, and the length of the Y-axis diagonal (long diagonal) is 250 μm.

[0095] The long diagonals of the diamond-shaped unit cells of the mesh structure were formed to be inclined at an angle of 2° with respect to the first direction (Y-axis direction).

Embodiment 2

[0097] The antenna device was formed by the same method as in Embodiment 1, except that the long diagonals of the rhombic unit cells of the mesh structure were formed to be inclined at an angle of 10° with respect to the first direction (Y-axis direction).

Abstract

An antenna device according to an embodiment of the present invention includes a dielectric layer and an antenna pattern disposed on a top surface of the dielectric layer. The antenna pattern includes a grid structure. A grid structure of the antenna pattern includes unit cells arranged repeatedly, and a diagonal line of each unit cell is inclined with respect to a width direction or a length direction of the antenna device. Provided is an antenna device having reduced pattern visibility and improved transmittance and signal sensitivity.

Description

[0001] Cross References and Priority Claims to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0161017 filed with the Korean Intellectual Property Office (KIPO) on December 5, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to an antenna device and a display device including the antenna device. More particularly, the present invention relates to an antenna device including a radiation pattern and a display device including the antenna device. Background technique [0004] With the development of information technology, wireless communication technologies such as Wi-Fi, Bluetooth, etc. are combined with display devices such as in the form of smart phones. In this case, the antenna may be combined with the display device to provide a communication function. [0005] With the rapid development of mobile communication technology, an antenna...
