Abstract
An electronic device () has a multi-state antenna ground structure () integrated into the device housing. Configuration of the electronic device () for use in one of at least two operable configurations automatically causes a switching of the ground structure to improve antenna efficiency. Metal plates () are secured within movable portions () of the device housing such that in a first configuration the metal plates are in close proximity and act as a low impedance path for switching the ground structure to a first state. In a second configuration of the electronic device () the plates are separated an act as a high impedance path for switching the ground structure to a second state.
