Abstract: A multi-standby portable terminal reduces interference of the transmitting antenna by skewing electromagnetic waves of others antennas. The terminal includes: a plurality of communication modules for transmitting and receiving RF signals of different frequency bands to and from the plurality of RF communication networks; and a controller for controlling the plurality of communication modules so as to be coupled to an RF communication network selected by a user, via a communication module corresponding to the selected RF communication network. The controller performs a control operation such that the communication module corresponding to the selected RF communication network radiates electromagnetic waves corresponding to a frequency band of the selected RF communication network, and remaining communication modules radiate electromagnetic waves of frequency bands that differ from those of respective corresponding RF communication networks.
