Abstract
An antenna assembly for transmitting a radio signal from a radio signal transmitting-device includes an antenna unit comprised of a dipole driven antenna member for transmitting a radio signal from the radio signal transmitting device. A radiation shielding member shields a user from a portion of the radio signal transmitted by the driven antenna member. The antenna unit may be pivotally mounted so that it is disposable at selectable positions relative to the shielding member. The dipole driven antenna member may include a first and a second segment made from a metal foil. The radiation reflector directs a portion of the radio signal away from the user toward an open transmission area, so as to extend a transmission range of the antenna assembly. At least some of the RF signal that is emitted from the driven antenna member toward the user is blocked by the radiation shielding member. Thus, the inventive antenna assembly has a compact construction, prevents unwanted exposure of the user to RF radiation, and provides an enhanced and extended transmission signal to enable improved communication.
