Patent ID: 6980160

Claim:
An antenna structure, comprising: a first radiation element with a first element drive contact; an RF drive contact coupled to an RF signal interface; and a moveable antenna element moveable between a first position and a second position, the moveable antenna element comprising a second radiation element, the moveable antenna element configured to: while in the first position, form a first conductive path between the RF drive contact and the first element drive contact while conductively isolating the RF drive contact from the second radiation element, thereby presenting a first impedance for the RF signal interface, and while in the second position, conductively isolating the RF drive contact from the first element drive contact while forming a second conductive path between the RF drive contact and the second radiation element, thereby presenting a second impedance for the RF signal interface; wherein the RF drive contact comprises a first contact and a second contact, the first contact forming part of the first conductive path when the moveable antenna element is in the first position and the second contact forming part of the second conductive path when the moveable antenna element is in the second position.
