Abstract

In an embodiment, an electronic device may include a first cover covering an upper portion of a main body and containing a first antenna module disposed on a lateral portion thereof, a spacer member disposed over the first cover, and a second cover disposed over the spacer member. The first and second covers may be spaced apart from each other at a predetermined distance due to the spacer member, and a separation space between the first and second covers may be configured to operate as a second antenna module. It is therefore possible to guarantee high-efficiency wireless performance having iso-directionality without compromising the design of the electronic device. Other embodiments are also possible.

First claim

What is claimed is:

1. An electronic device comprising:
a first cover covering an upper portion of a main body and containing a first antenna module disposed on a lateral portion thereof;
a spacer member disposed over the first cover; and
a second cover disposed over the spacer member,
wherein the first and second covers are spaced apart from each other at a predetermined distance due to the spacer member, and
wherein a separation space between the first and second covers is configured to operate as a second antenna module.

2. The electronic device of claim 1 , wherein each of the first and second covers is made of a metallic material, and the spacer member is made of a non-conductive material.

3. The electronic device of claim 1 , wherein the first antenna module includes:
a slot formed in a part of the lateral portion of the first cover;
an antenna printed circuit board (PCB) disposed, at a position corresponding to the slot, near an inner surface of the lateral portion; and
a fixing member configured to fix the antenna PCB.

4. The electronic device of claim 3 , wherein the antenna PCB of the first antenna module is disposed vertically with respect to the first cover.

5. The electronic device of claim 4 , further comprising an area having no metallic material disposed above the antenna PCB.

6. The electronic device of claim 3 , wherein a width of the separation space between the first and second covers is greater than a width of the slot.

7. The electronic device of claim 3 , wherein the slot has a stepped portion formed along an edge of the slot, and a plate is mounted on and engaged with the stepped portion to close the slot.

8. The electronic device of claim 3 , wherein the antenna PCB includes a power feeder and an antenna pattern to operate the slot as an antenna.

9. The electronic device of claim 3 , wherein the fixing member has at least one engaging hole engaged with at least one engaging protrusion disposed around the antenna PCB.

10. The electronic device of claim 3 , wherein a ground layer is formed integrally with and extended from a lower portion of the antenna PCB to be perpendicular to the antenna PCB.

11. The electronic device of claim 3 , wherein the first antenna module further comprises a wall portion surrounding at least a part of the fixing member.
