description PCT No. PCT/IB96/00649 Sec. 371 Date Apr. 15, 1998 Sec. 102(e) Date Apr. 15, 1998 PCT Filed Jul. 4, 1996 PCT Pub. No. WO97/02621 PCT Pub. Date Jan. 23, 1997An antenna assembly (10) has a rotatable antenna arm (15) with an active portion (20) and a switching portion (25), a ground plane (30) and an inductive loop element (35) connected to the ground plane. In a first position of the arm (15), the arm is generally parallel to the ground plane (30) and the switching portion (25) is connected to the inductive loop element (35), forming a transmission line antenna. In a second position of the arm (15), the arm is extended away from the ground plane (30) and the switching portion (25) is disconnected from the inductive loop element (35), thus forming a whip antenna.
