Abstract
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 antennaincludes a first ground pattern, a second ground pattern, a hinge conductor memberand a current control circuit. The first ground patternis formed on a first printed wiring board. The hinge conductor memberis arranged on a hinge Z which connects indirectly the first printed wiring boardand a second printed wiring boardeach other. The current control circuitis arranged on the first printed wiring board. The current control circuithas 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 sourceto the second ground patternand flows into the first ground patternthrough the hinge conductor memberand the current control circuit. 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 sourceto the second ground patternand flows until reaching the current control circuitthrough the hinge conductor member. 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.
