ANTENNA ASSEMBLY AND COMMUNICATIONS DEVICE

摘要

An antenna assembly has a rotatable antenna arm with an active portion and a switching portion, a ground plane and an inductive loop element connected to the ground plane. In a first position of the arm, the arm is generally parallel to the ground plane and the switching portion is connected to the inductive loop element, forming a transmission line antenna. In a second position of the arm, the arm is extended away from the ground plane and the switching portion is disconnected from the inductive loop element, thus forming a whip antenna.
