    摘要: An object of the present invention is to provide an antenna feeding circuit, which requires no balance-unbalance converter and has a simplified structure. The object is attained, by an antenna feeding circuit, according to the present invention, in which micro-strips lines are constituted from one or more pair(s) of band conductors (5a, 5b) disposed on the outer surface of the cylindrical body (1) and an inner conductor (6) disposed on the whole of the inner surface of the cylindrical body (1). A 180 degree distributor (2) supplies electric power to the band conductors (5a, 5b) so that the phase difference between the currents in the band conductors (5a, 5b) is 180 degrees. Inutile current induced in the inner surface of the inner conductor can be cancelled out, because the inner conductor 6 is disposed on the whole of the inner surface of the cylindrical body (1).

    摘要: When the portable wireless device of the present invention is used, the second housing 3 with the antenna unit 4 telescopically received therein is turned about the hinge 2 to a spread position where the antenna unit 4 is spread out a sufficient distance away from the housing 1 and is extended from the second housing 3. Hence, during communication the antenna unit 4 is kept sufficiently far apart from the user's head 100 to provide improved transmission and/or reception characteristics.

    摘要: A wireless communication device whose impedance can be matched with an arbitrary load impedance and that can be broadened in operating frequency band even when choosing an input impedance of an IC chip freely is not possible. The wireless communication device includes: a first conductor; a second conductor disposed substantially parallel to the first conductor; a hole formed in the second conductor; a capacitive coupling mechanism disposed adjacent to the hole; and a communication circuit which has at least one of a radio wave transmitting function and a radio wave receiving function. The communication circuit is connected through the capacitive coupling mechanism to two sites on the second conductor that are near borders between the second conductor and the hole.
