<p>The present invention enables to restrain the enlargement of the wireless communication apparatus and prevent the manufacturing processes from increasing and to increase the frequency bands which can be used by the wireless communication. An antenna 1 includes a first ground pattern 3, a second ground pattern 4, a hinge conductor member 5 and a current control circuit 6. The first ground pattern 3 is formed on a first printed wiring board 7. The hinge conductor member 5 is arranged on a hinge Z which connects indirectly the first printed wiring board 7 and a second printed wiring board 8 each other. The current control circuit 6 is arranged on the first printed wiring board 7. The current control circuit 6 has a function to flow the electric current of a first frequency band and attenuate the electric current of a second frequency band. An electric current of the first frequency band flows from a feeding source 10 to the second ground pattern 4 and flows into the first ground pattern 3 through the hinge conductor member 5 and the current control circuit 6. A part, on which the electric current of the first frequency band flows, functions as an antenna which communicate the signal of the first frequency band. An electric current of the second frequency band flows from the feeding source 10 to the second ground pattern 4 and flows until reaching the current control circuit 6 through the hinge conductor member 5. A part, on which the electric current of the second frequency band flows, functions as an antenna which communicate the signal of the second frequency band.</p> |
