A portable wireless apparatus 100 connects, with a thin coaxial cable 121, electrical signals of first and second circuit members 111 and 112 housed within first and second casings 101 and 102 that are openably/closably joined by a third casing 103 comprising a hinge portion 104, connects the first and second circuit members 111 and 112 with a connecting element 122 via a reactance-switchable reactance element 123, and comprises, at the second casing 102 near the hinge portion 104, first, second and third antennas 131, 132 and 133. Even if the first casing 101 is rotated by approximately 90 degrees within substantially the same plane, favorable antenna characteristics are attained at a given frequency by switching the connection impedance of the first and second casings 101 and 102 depending on the respective used frequencies for each state of the terminal. Thus, it becomes possible to provide a portable wireless apparatus in which inter-casing connection is established in an ideal manner by switching the connection impedance between the casings at a given frequency, and in which favorable antenna characteristics are attained at given frequencies for each given state. |
