ABSTRACT:
A mobile phone includes a main body, a cover member and an antenna assembly having a radiating metal strip and a matching circuit. The radiating metal strip has a feeding leg and a short-circuit leg coupled electrically to the matching circuit in such a manner that the latter provides impedance matching for the antenna assembly. A switching unit couples the cover member pivotally on the main body, and determines whether the mobile phone is in a first operating mode or a second operating mode. Either in the first or second operating mode, the antenna assembly in the mobile phone has similar characteristic by virtue of the impedance matching provided by the matching circuit.
