Patent ID: 8774856

Claim:
A multi-standby portable terminal that can be coupled to a plurality of radio frequency (RF) communication networks, comprising: 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 a selected RF communication network of the plurality of RF communication networks, via a communication module of said plurality of communication modules corresponding to the selected RF communication network, and for controlling a switching to a frequency band of the selected RF communication network; wherein the controller is configured to perform a control operation in which 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 a remainder of communication modules other than the communication module corresponding to the selected RF communication network radiates electromagnetic waves of frequency bands that differ from those of respective corresponding RF communication networks, wherein each of the plurality of communication modules comprises a first antenna pattern tuned for operation in the frequency bands for each of the communication modules and a second antenna pattern formed separately from the first antenna pattern to have frequency bands differing from the first antenna pattern, and wherein when the first antenna pattern of a first communication module corresponding to the selected RF communication network radiates electromagnetic waves to communicate with the selected RF communication network, the second antenna pattern of other communication module radiates electromagnetic waves in order to skew the electromagnetic waves of the first antenna pattern of other communication modules.
