The first intermediate antenna 320 is formed on the inner surface of the cover 203. However, the first intermediate antenna 320 is disposed so as not to overlap the electronic components disposed in the terminal main body so as not to interfere with transmission and reception of a signal. For example, the power supply unit 222 may be formed so as not to overlap the power supply unit 222.

The first intermediate antenna 320 is formed in a loop of the main antenna 310. Since the first intermediate antenna 320 transmits a signal to a relatively adjacent second intermediate antenna 330, the first intermediate antenna 320 may be formed in a short loop compared to the main antenna 310. Both ends of the loop of the first intermediate antenna 320 are connected to both ends of the loop of the main antenna 310 to receive the signal.

The second intermediate antenna 330 is formed on the surface opposite to the surface facing the cover 203 of the rear case 202, that is, the surface facing the inside of the terminal body. Accordingly, the first and second intermediate antennas 330 are disposed with the rear case 202 interposed therebetween. In order to improve performance of wireless communication, the first and second intermediate antennas 320 and 330 may be formed to overlap each other.

Accordingly, the main antenna 310 detects a change in magnetic flux outside the terminal body and generates a signal. The signal is transmitted to the first intermediate antenna 320 which is electrically connected to the main antenna 310. The first and second intermediate antennas 320 and 330 transmit the signal to the second intermediate antenna 330 using wireless communication, and the signal is transmitted to the circuit board 281.

A ferrite sheet (not shown) may be formed on the main antenna 310 overlapping with the power supply unit 222. The ferrite sheet limits the interference to the magnetic flux change generated by the power supply unit 222. More specifically, the ferrite sheet removes the noise for receiving the flux change.

The mobile terminal may further include a blocking unit 206. The blocking unit 206 is formed to block water that may flow into the terminal body and flow between the power supply units 222. That is, the coupling portion protruding from the inner surface of the blocking portion 206 is formed, the rear case 202 is formed with a groove, the coupling portion is a structure that is fitted into the groove. The coupling portion may be formed of an elastic material to block the incoming water. That is, the waterproof function of the mobile terminal can be improved.

Since the main antenna 310 transmits a signal using the first and second intermediate antennas 320 and 330, a contact for implementing an electrical connection is unnecessary, which is advantageous for the waterproof function.

In addition, the cover 203 is detachably formed, and a plurality of covers in which various kinds of antennas are implemented may be used in combination with the terminal body. Therefore, the mobile terminal having various wireless communication functions can be implemented only by replacing the cover 203.

Accordingly, the main antenna 310 for implementing wireless communication according to an embodiment of the present invention does not require a contact for electrically connecting with the circuit board 281 disposed inside the main body of the terminal. Since the contact formed by protruding the cover 203 and the rear case 202 is unnecessary, a simple structure and an additional design can be easily formed.
