Abstract

A portable terminal is provided. The portable terminal includes a back surface on which a battery-mounting groove is formed; and a receiving-side resonant antenna arranged around the battery-mounting groove on the body. The receiving-side resonant antenna is arranged parallel to at least three sides of the battery-mounting groove.

Claims

1. A portable terminal comprising:

a body having a back surface;

a battery mounting groove formed on the back surface;

an accommodation groove formed on the back surface around a circumference of the battery mounting groove, the accommodation groove having a shape and a depth of a receiving-side resonant antenna, the receiving-side resonant antenna attached to the accommodation groove; and

an electromagnetic shielding member provided on the body, wherein the electromagnetic shielding member comprises;

a first shielding portion attached to an inner wall of the accommodation groove between the battery mounting groove and the receiving-side resonant antenna; and

a second shielding portion attached to a bottom surface of the accommodation groove between the receiving-side resonant antenna and a circuit device.

2. The portable terminal as claimed in claim 1, wherein the second shielding portion extends from the first shielding portion.

3. The portable terminal as claimed in claim 1,

wherein the receiving-side resonant antenna is attached to the electromagnetic shielding member.

4. The portable terminal as claimed in claim 1, further comprising an insulation member provided to wrap the receiving-side resonant antenna.

5. The portable terminal as claimed in claim 1, wherein the circuit device comprises a main circuit board which is accommodated inside the body and on which a receiving circuit unit is disposed, the receiving-side resonant antenna being connected to the receiving circuit unit.

6. The portable terminal as claimed in claim 5, wherein the receiving circuit unit includes a charging control circuit chip.
