To provide a mobile wireless communications device, having antenna design which can be incorporated as a sub-assembly, having at least a keyboard circuit board for restraining the complexity.
The mobile wireless communication device contains a housing and a main circuit board (67), which is accommodated in the housing and has a circuit network on it. The keyboard circuit board (44) is accommodated in the lower housing (47) and has a keyboard (44a) and a keyboard circuit network (44b), connected to the circuit network on the main circuit board on it. An antenna (44c) on the keyboard circuit board is formed as an antenna, is placed at the lower housing, has a conductive trace pattern that forms an antenna circuit (44d), and is connected to the circuit network on the main circuit board. The keyboard circuit board (44), preferably, is provided with a flex circuit.
