A mobile communication terminal comprises a shell, and a backfire antenna which includes a main board disposed in the shell and having a transmitting circuit and a receiving circuit on the main board; a main antenna element coupled to the transmitting circuit and the receiving circuit on the main board; and a backfire resonator located at a side of the shell deviated from a user's head, and coupled to the main board and the main antenna element, in which the backfire resonator is fed by the main board from a position on the main board deviated from a center of the main board. The mobile communication terminal according to embodiment of the present disclosure may cause most electromagnetic waves to radiate towards a direction deviated form the user, thus reducing radiation and harm thereof to the user, strengthening the signal received by the base station, and improving the communication quality.
