Abstract

In a portable radio communication apparatus comprising an insulating case having an inner surface and a printed board housed in the insulating case, an antenna conductive film is coated on a predetermined region of the inner surface of the insulating case. A conductive ground film is coated on the remaining region of the inner surface of the insulating case with a constant gap from the outer periphery of the antenna. A first conductive member connects the antenna film with the conductive ground film. A plurality of second conductive members connects the conductive ground film with a ground pattern of a radio communication circuit on the printed board. A feeding member connects the antenna with an antenna terminal pad of the radio communication circuit.
The second conductive members and feeding member are conductive rods.
