Abstract

According to various embodiments of the disclosure, an electronic device may include: a housing, a rollable display, a shielding case disposed inside the housing and surrounding at least a part of the rollable display, and including a first opening accommodating the rollable display, and a first antenna structure including at least one antenna disposed in an area outside the shielding case.

First claim

What is claimed is:

1 . An electronic device comprising:
a housing; a rollable display; a shielding case disposed inside the housing and surrounding at least a part of the rollable display, and including a first opening to accommodate movement of the rollable display; and a first antenna structure including at least one antenna disposed in an area outside the shielding case.

2 . The electronic device of claim 1 , further comprising a second antenna structure including at least one antenna disposed in an area inside the housing,
wherein at least a part of the second antenna structure is disposed to face the first antenna structure.

3 . The electronic device of claim 2 , further comprising an antenna bridge disposed between the housing and the shielding case and electrically coupling or connecting the first antenna structure and the second antenna structure to each other.

4 . The electronic device of claim 3 , wherein one end of the antenna bridge is directly coupled or connected to a part of the second antenna structure, and another end of the antenna bridge is directly coupled or connected to a part of the first antenna structure.

5 . The electronic device of claim 3 , wherein one end of the antenna bridge is directly coupled or connected to a part of the second antenna structure, and another end of the antenna bridge is disposed apart from a part of the first antenna structure by a specified distance and coupled or connected to the part of the first antenna structure.

6 . The electronic device of claim 1 , further comprising a battery disposed inside the shielding case and configured to allow the rollable display to be wound around the battery.

7 . The electronic device of claim 1 , wherein the housing includes a second opening through which the rollable display is accommodated into the housing or withdrawn from the housing, and
wherein the first opening of the shielding case is disposed in parallel to the second opening.

8 . The electronic device of claim 7 , wherein the shielding case has a substantially cylindrical shape, and
wherein the first antenna structure is located opposite the first opening with respect to an outer surface of the shielding case.

9 . The electronic device of claim 2 , wherein a first resonant property of the first antenna structure or the second antenna structure in a slide-in state of the rollable display is similar to a second resonant property of the first antenna structure or the second antenna structure in a slide-out state of the rollable display.

10 . The electronic device of claim 1 , wherein the shielding case comprises a conductive material configured to limit an electromagnetic effect between the first antenna structure and the rollable display.

11 . The electronic device of claim 2 , wherein an antenna frequency band range provided by electrical coupling between the first antenna structure and the second antenna structure is larger than an antenna frequency band range provided by the first antenna structure or the second antenna structure.

12 . The electronic device of claim 1 , wherein the shielding case includes a cylindrical conductive structure comprising a conductive material and a dielectric layer disposed to surround an outer surface of the conductive structure and comprising a non-conductive material, and
wherein the first antenna structure includes a first part and a second part symmetrical horizontally or vertically with respect to a first axis perpendicular to a rotation axis of the rollable display.

13 . The electronic device of claim 12 , wherein the first antenna structure includes a part from which an area of the dielectric layer of the shielding case is removed and a conductive structure is exposed.

14 . The electronic device of claim 1 , wherein the shielding case includes a cylindrical conductive part comprising a conductive material, and
wherein the first antenna structure includes an area of the conductive structure and a slot part surrounded by the conductive part.

15 . The electronic device of claim 2 , further comprising a circuit board disposed between the housing and the shielding case and on which a communication circuit electrically coupled to the first antenna structure or the second antenna structure is mounted.
