Abstract

An electronic device is provided. The electronic device includes a housing and a display. The display is arranged in the inner space of the housing while being visible from the outside, and includes a curved side portion. The display includes a plurality of conductive mesh patterns that form an antenna. The plurality of conductive mesh patterns includes a first conductive mesh pattern arranged in a first portion of the display and a second conductive mesh pattern arranged on a second portion of the outer periphery of the first portion. The first conductive mesh pattern and the second conductive mesh pattern have different shapes.

First claim

What is claimed is:

1. An electronic device comprising:
a housing; and
a display disposed in an inner space of the housing while being visible from outside the housing and comprising a curved side surface portion,
wherein the display comprises a plurality of conductive mesh patterns which configure an antenna,
wherein the plurality of conductive mesh patterns comprise a first conductive mesh pattern disposed in a first portion of the display and a second conductive mesh pattern disposed in a second portion of an outer periphery of the first portion, and
wherein the first conductive mesh pattern and the second conductive mesh pattern have different shapes based on a sheet resistance of the antenna and an intersection angle of the plurality of conductive mesh patterns.

2. The electronic device of claim 1 , wherein the first conductive mesh pattern has a shape of a square or a rhombus.

3. The electronic device of claim 2 , wherein the second conductive mesh pattern has a shape of a rhombus having a longer length in a first direction.

4. The electronic device of claim 3 , further comprising:
a third conductive mesh pattern disposed in a third portion of an outer periphery of the second portion,
wherein the third conductive mesh pattern is configured to have a shape different from that of the first and the second conductive mesh pattern.

5. The electronic device of claim 4 , wherein the third conductive mesh pattern has a shape of a rhombus having a longer length in a first direction.

6. The electronic device of claim 5 , wherein the third conductive mesh pattern is configured to have a shape having a length in the first direction which is longer than that of the second conductive mesh pattern.

7. The electronic device of claim 4 ,
wherein the first portion comprises a center portion of the display,
wherein the second portion comprises an edge of the display, and
wherein the third portion comprises the curved side surface portion of the display.

8. The electronic device of claim 4 ,
wherein in case that a current of the antenna flows in the first direction, the second conductive mesh pattern and the third conductive mesh pattern are configured to have a length in the first direction and a length in a second direction orthogonal to the first direction, and
wherein the length in the first direction is different from the length in the second direction.

9. The electronic device of claim 8 , wherein the second conductive mesh pattern and the third conductive mesh pattern are configured such that the length in the first direction is longer than the length in the second direction.

10. The electronic device of claim 9 , wherein the second conductive mesh pattern is configured such that the closer to the first portion, the shorter the length in the first direction.

11. The electronic device of claim 9 , wherein the third conductive mesh pattern is configured such that the closer to the first portion, the shorter the length in the first direction.

12. The electronic device of claim 9 ,
wherein the display comprises a display panel, a polarizing layer disposed on the display panel, a dielectric layer disposed on the polarizing layer, a window disposed on the dielectric layer, and a flexible printed circuit board (FPCB) electrically connected to the dielectric layer, and
wherein the first to the third conductive mesh patterns are configured on the dielectric layer.

13. The electronic device of claim 1 ,
wherein the first conductive mesh pattern has a shape of a rhombus having the longer length in a first direction, and
wherein the second conductive mesh pattern has a shape of a hexagon.

14. The electronic device of claim 13 , further comprising:
a third conductive mesh pattern disposed in a third portion of the outer periphery of the second portion,
wherein the third conductive mesh pattern has a shape of a hexagon having the longer length in the first direction.

15. The electronic device of claim 14 , wherein, in case that a current of the antenna flows in the first direction, the third conductive mesh pattern is configured to have a shape having a length in the first direction longer than that of the second conductive mesh pattern.
