ABSTRACT:
An antenna assembly for a cellular telephone reduces electrical signal interference caused by the close proximity of the antenna to the user's head. The antenna assembly includes a coil antenna mounted on the top of a telescoping rod member. Only the coil antenna is adapted for transmitting and receiving electrical signals. The coil antenna is electrically connected, via a coaxial cable, to a telephone transceiver circuit board. In operation, the telescoping rod member is extended until the coil antenna is positioned at a height above the user's head to minimize the transmission of electrical signals toward the user's head.
