Patent ID: 8681062

Claim:
An antenna, comprising: a first ground pattern that is formed on a first printed wiring board; a second ground pattern that is formed on a second printed wiring board on which a feeding source, which outputs an electric current of a first frequency band and a electric current of a second frequency band higher than the first frequency band, is arranged; a hinge conductor member that is arranged on a hinge which connects indirectly the first printed wiring board and the second printed wiring board each other; and a current control circuit that is arranged on the first printed wiring board, flows the electric current of the first frequency band, and attenuates the electric current of the second frequency band, wherein the first ground pattern connects electrically with at least one out of a plurality of input and output ports, which the feeding source includes, through the current control circuit and the hinge conductor member, the second ground pattern connects electrically with another input and output port of the feeding source, the first ground pattern, the current control circuit, the hinge conductor member and the second ground pattern function as an antenna to communicate a signal of the first frequency band, and the hinge conductor member and the second ground pattern function as an antenna to communicate a signal of the second frequency band.
