Abstract

An electronic device includes a housing antenna formed from a conductive material. At least parts of a side member and a rear cover that constitute the housing of the electronic device are used as an antenna. Accordingly, radiation patterns generated by this antenna are formed on the rear surface of the electronic device as well as at the upper portion of the electronic device. It is therefore possible to perform wireless communication with higher accuracy.

First claim

What is claimed is:

1. An electronic device comprising:
a housing including a first plate, a second plate facing in a reverse direction of the first plate, and a side member surrounding the first and second plates, wherein at least a portion of the second plate is made of a conductive material;
a touch screen display exposed through the first plate;
a processor disposed between the first and second plates; and
a wireless communication circuit disposed between the first and second plates and electrically connected to the processor,
wherein the second plate has a rectangular shape including:
a first side having a first length and extending in a first direction;
a second side having a second length greater than the first length and extending in a second direction perpendicular to the first direction;
a third side having the first length and extending parallel with the first side in the first direction; and
a fourth side having the second length and extending parallel with the second side in the second direction,
wherein the second plate includes:
a first slit disposed between the first and third sides and extending in the first direction from a first position on the second side, as viewed in a top view of the second plate;
a second slit aligned with the first slit, extending in the first direction from a second position on the fourth side, and spaced apart from the first slit, as viewed in the top view of the second plate;
an opening formed in a portion of the second plate between the third side and at least one of the first and second slits, as viewed in the top view of the second plate;
a third slit extending from the second slit to the opening, as viewed in the top view of the second plate; and
a non-conductive material filling the first slit, the second slit, the third slit, and/or the opening, and
wherein the side member includes:
a conductive region extending from the first position to the second position along a portion of the second side, the first side, and a portion of the fourth side;
a fourth slit disposed at the first position corresponding to the first slit of the second plate; and
a fifth slit disposed at the second position corresponding to the second slit of the second plate.

2. The electronic device of claim 1 , wherein:
a first terminal of the wireless communication circuit is electrically connected to the second plate at a first point disposed adjacent to the fourth side and between the first side and the second slit, and
a second terminal of the wireless communication circuit is electrically connected to the second plate at a second point disposed adjacent to the fourth side and between the third side and the second slit.

3. The electronic device of claim 2 , wherein the wireless communication circuit includes a near field communication (NFC) integrated circuit (IC) that supplies a radio frequency (RF) signal to the first and second points.

4. The electronic device of claim 3 , wherein when the wireless communication circuit supplies the RF signal to the first and second points, a signal path is formed from the first point, through a portion of the second plate between the first and second slits, around a circumference of the opening, and to the second point.

5. The electronic device of claim 4 , further comprising:
at least one inductor electrically connected between the NFC IC and at least one of the first and second points.

6. The electronic device of claim 1 , wherein a first terminal of the wireless communication circuit is electrically connected to the second plate at a first point disposed adjacent to the third slit and between the second slit and the opening.

7. The electronic device of claim 6 , further comprising:
a wound coil having an axis perpendicular to the second plate and disposed in the housing adjacent the opening.

8. The electronic device of claim 1 , wherein the wireless communication circuit is configured to support a near field communication (NFC) protocol.

9. An electronic device comprising:
a housing including a first plate, a second plate facing in a reverse direction of the first plate, and a side member surrounding the first and second plates, wherein at least a portion of the second plate is made of a conductive material;
a touch screen display exposed through the first plate;
a processor disposed between the first and second plates; and
a wireless communication circuit disposed between the first and second plates and electrically connected to the processor,
wherein the second plate has a rectangular shape including:
a first side having a first length and extending in a first direction;
a second side having a second length greater than the first length and extending in a second direction perpendicular to the first direction;
a third side having the first length and extending parallel with the first side in the first direction; and
a fourth side having the second length and extending parallel with the second side in the second direction,
wherein the second plate includes:
a first slit disposed between the first and third sides and extending in the first direction from a first position on the second side, as viewed in a top view of the second plate;
a second slit aligned with the first slit, extending in the first direction from a second position on the fourth side, and spaced apart from the first slit, as viewed in the top view of the second plate;
an opening formed in a portion of the second plate between the first side and at least one of the first and second slits, as viewed in the top view of the second plate; and
a non-conductive material filling the first slit, the second slit, and/or the opening, and
wherein the side member includes:
a conductive region extending from the first position to the second position along a portion of the second side, the first side, and a portion of the fourth side;
a third slit disposed at the first position corresponding to the first slit of the second plate; and
a fourth slit disposed at the second position corresponding to the second slit of the second plate.

10. The electronic device of claim 9 , wherein:
a first terminal of the wireless communication circuit is electrically connected to the second plate at a first point disposed between the opening and the second slit, and
a second terminal of the wireless communication circuit is electrically connected to the second plate at a second point disposed adjacent to the fourth side and between the third side and the second slit.

11. The electronic device of claim 10 , wherein when the wireless communication circuit supplies a RF signal to the first and second points, a signal path is formed from the first point, through a first portion of the second plate surrounding the opening, a second portion of the second plate between the first side and the second slit, a third portion of the second plate between the first and second slits, a fourth portion of the second plate between the second slit and the third side, and to the second point.

12. An electronic device comprising:
