摘要：An electronic device () has a multi-state antenna ground structure () integratedinto the device housing. Configuration of the electronic device () for use in one of at leasttwo operable configurations automatically causes a switching of the ground structure to
improve antenna efficiency. Metal plates () are secured within movable portions () of thedevice housing such that in a first configuration the metal plates are in close proximityand act as a low impedance path for switching the ground structure to a first state. In asecond configuration of the electronic device () the plates are separated an act as a highimpedance path for switching the ground structure to a second state.
