Abstract

A portable terminal is provided, including a cover member which is detachably provided at a rear surface of a main body of a terminal, a resonant antenna for a reception unit provided inside of the cover member, a reception circuit unit provided inside of the main body, and a connection unit for connecting the resonant antenna for a reception unit with the reception circuit unit. The portable terminal efficiently receives the signal power provided from a charger by arranging the resonant antenna inside of the cover member, and minimizes the thickness of the portable terminal by providing the reception circuit unit inside of the main body of the terminal.

Claims

1. A portable terminal, comprising:

a cover member that is detachably provided on a back surface of a body of the portable terminal;

a receiving-side resonant antenna provided on an inner surface of the cover member;

a receiving circuit unit accommodated inside the body of the portable terminal; and

a connection device that electrically connects the receiving-side resonant antenna and the receiving circuit unit.

2. The portable terminal of claim 1, wherein the receiving circuit unit includes a wireless charging circuit.

3. The portable terminal of claim 1, wherein receiving-side resonant antenna is attached to the inner surface of the cover member.

4. The portable terminal of claim 1, wherein the receiving-side resonant antenna is configured as a receiving-side resonator.

5. The portable terminal of claim 1, further comprising a second cover member attached to the cover member and concealing the receiving-side resonant antenna.

6. The portable terminal of claim 5, wherein the second cover member is a shielding member that is interposed between the receiving-side resonant antenna and the body of the portable terminal.

7. The portable terminal of claim 1, wherein the connection device includes:

a connection pad fixed to the inner surface of the cover member while being connected to the receiving-side resonant antenna; and

a connection terminal exposed to the back surface of the body of the portable terminal while being electrically connected to the receiving circuit unit,

wherein the connection pad physically contacts the connection terminal when the cover member is coupled to the body of the portable terminal.

8. The portable terminal of claim 7, wherein the receiving-side resonant antenna is made of a copper plate and the connection pad is provided at an end of a flexible printed circuit board that extends from the receiving-side resonant antenna.

9. The portable terminal of claim 7, further comprising a battery-mounting groove formed on the back surface of the body of the portable terminal,

wherein the connection terminal is provided at a side of the mounting groove.

10. A portable terminal, comprising:

a body formed with a battery-mounting groove on a back surface of the body;

a cover member that is detachably provided on the back surface of the body of the portable terminal to open and close the battery-mounting groove;

a receiving-side resonant antenna provided on an inner surface of the cover member; and

a receiving circuit unit accommodated inside the body,

wherein, when the cover member is coupled to the body, the receiving-side resonant antenna is electrically connected to the receiving circuit unit, and the receiving circuit unit includes a wireless charging circuit.

11. The portable terminal of claim 10, wherein the receiving-side resonant antenna is attached to the inner surface of the cover member.

12. The portable terminal of claim 11, wherein the receiving-side resonant antenna is configured as a receiving-side resonatornator).

13. The portable terminal of claim 10, further comprising an electromagnetic shielding member interposed between the receiving-side resonant antenna and the body.

14. The portable terminal of claim 13, wherein the electromagnetic shielding member is attached to the inner surface of the cover member.
