Abstract (en)

[origin: EP1898490A1] In order for antenna characteristics of a combination of an antenna and a passive element to avoid the influence of the length of a circuit board in which the antenna and the passive element are disposed, a mobile communication terminal capable of being folded includes a first casing and a second casing, in which a power feeding antenna 16 is provided in a first circuit board included in the first casing and a passive antenna 26 is provided in a second circuit board included in the second casing. Further, a switch is provided between the second circuit board and the passive antenna 26 and, the passive antenna is connected only when the terminal is in a predetermined state.
