Abstract

An antenna assembly includes a circuit board, a substrate extended from one side of the circuit board, a conductive member provided the other side of the circuit board, and a GPS antenna connected to the conductive member and arranged opposite to the second side of the substrate, one or more antenna devices and a GSM antenna are disposed on the circuit board and arranged opposite to the GPS antenna for preventing the GPS antenna and the antenna devices and the GSM antenna from being interfered or affected by each other and for allowing the antenna assembly to suitably transmit and receive the signals.
