Abstract (en)
A portable radio device includes a first casing (210), a second casing (211), a connection portion (212b) which connects the first casing with the second casing so as to freely rotate, a first antenna element (214) which is provided in the first casing, a second antenna element (221) which is provided in the second casing, and a feeding portion (220a,220b) which has one end electrically connected to the first antenna element through the connection portion and the other end electrically connected to the second antenna element. The connection portion has an electric conductivity, and the connection portion is arranged away from the second antenna element at a distance. The first antenna element, the connection portion and the second antenna element form a dipole antenna.
