Antenna module and electronic device comprising thereof

1. An electronic device comprising:

a housing;

a plate attached to the housing to form an inner space together with the housing and including a flat portion facing in a first direction and a curved portion extended from an edge of the flat portion and forming an obtuse angle with the first direction; and

an antenna module positioned in the inner space,

wherein the antenna module includes:

a first partial layer having a first size,

a second partial layer including a first antenna pattern, having a second size smaller than the first size, and stacked on the first partial layer, and

a third partial layer including a second antenna pattern, having a third size smaller than the second size, and stacked on the second partial layer, and

wherein, when viewed from the first direction, the third partial layer overlaps at least a portion of the flat portion, and at least a portion of the second partial layer overlaps at least a portion of the curved portion.

2. The electronic device of claim 1 ,

wherein the first partial layer includes a first region exposed by a difference between the first size of the first partial layer and the second size of the second partial layer,

wherein the second partial layer includes a second region exposed by a difference between the second size and the third size, and

wherein the third partial layer includes a third region facing in the first direction.

3. The electronic device of claim 2 , further comprising:

a support member fixing the antenna module to a printed circuit board disposed in the housing,

wherein the first region has a shape of engaging with a portion of the support member.

4. The electronic device of claim 2 , wherein a distance between the flat portion and the third region is smaller than a distance between the curved portion and the second region.

5. The electronic device of claim 2 , wherein the first region overlaps at least a portion of the flat portion, when viewed from the first direction.

6. The electronic device of claim 2 ,

wherein the antenna module has a first thickness in the third region,

wherein the antenna module has a second thickness smaller than the first thickness in the second region, and

wherein the antenna module has a third thickness smaller than the second thickness in the first region.

7. The electronic device of claim 1 , wherein the second partial layer includes at least one dipole antenna.

8. The electronic device of claim 7 , further comprising:

a wireless communication circuit configured to transmit/receive a signal having a frequency between 3.5 GHz and 100 GHz by using the dipole antenna.

9. The electronic device of claim 7 , wherein the first partial layer or the third partial layer includes at least one S-patch antenna for improving a straightness of a signal which is transmitted/received through the dipole antenna.

10. The electronic device of claim 1 , wherein the third partial layer includes at least one patch antenna.

11. The electronic device of claim 10 , further comprising:

a wireless communication circuit configured to transmit/receive a signal having a frequency between 3.5 GHz and 100 GHz by using the patch antenna.

12. The electronic device of claim 1 , further comprising:

a side bezel structure, formed of a metal material, to which the plate is attached,

wherein the side bezel structure includes an injection structure of a polymer material, which is disposed at a location corresponding to the antenna module.

13. The electronic device of claim 1 , wherein the antenna module further comprises a network layer.

14. The electronic device of claim 13 , wherein the network layer comprises:

at least one dielectric layer; and

at least one ground layer.

15. The electronic device of claim 14 , further comprising a radio frequency integrated circuit (RFIC),

wherein the RFIC is electrically connected with an antenna element of the antenna module through a feed part formed within the dielectric layer.
