<P>PROBLEM TO BE SOLVED: To provide a hinge-incorporated antenna device, in which two-foldable portable radio equipment is automatically opened by pressing a button and which operates as an antenna. <P>SOLUTION: In the hinge-incorporated antenna 101, a one-push hinge 102 made of metal is connected to a power supply part 104 via an antenna element 103. One end part of an almost cylindrical fixed part 102a of the one-push hinge 102 is concentrically connected to a similarly almost cylindrical sliding part 102b in a rotatable state, and a button part 102c is connected to the other end part of the fixed part 102a. One end part of an electrical length correcting element 103a is electrically connected to the surface of a side face part of the fixed part 102a via a connection part 103d of an antenna element 103, and a resonance element 103b is connected to the other end of the electrical length correcting element 103a. A connection point between the electrical length correction element 103a and the resonance element 103b is connected to the power supply part 104 via an electric supply line 103c. <P>COPYRIGHT: (C)2009,JPO&INPIT |
