Patent ID: 8355761

Claim:
A mobile terminal comprising: at least a first casing and a second casing which are coupled together in a manner in which a combined configuration of said first and second casings can be varied, said first casing having at least a radio circuit and a first antenna connected to said radio circuit, and said second casing having at least a second antenna, wherein said first casing has a feed element connected to said radio circuit, wherein when the combined configuration of said first and second casings is a predetermined configuration, said feed element of said first casing and said second antenna of said second casing are close to each other and are capacitively coupled together, so that said second antenna is connected with said radio circuit through said feed element via high-frequency waves, wherein said first casing has a configuration detection section for detecting the combined configuration of said first and second casings, and a switching circuit for, based on a control signal from said configuration detection section, connecting said radio circuit either to said first antenna or to said feed element, and wherein said switching circuit connects said radio circuit with said feed element when the combined configuration of said first and second casings is the predetermined configuration, and connects said radio circuit with said first antenna when the combined configuration of said first and second casings is a configuration other than the predetermined configuration.
