PURPOSE: A combination antenna device/stylus pen is provided to achieve improved user convenience by eliminating the need of stylus pen for pressing the touch screen of portable radio terminal. CONSTITUTION: An antenna device(300) installed to a housing(100) of a main body of a terminal, includes a helical antenna(310) fixed to the main body of the terminal, and a rod antenna(320) arranged to be extendable/retractable from/into the helical antenna. The rod antenna has a contact portion(321) which is formed sharp to press the touch screen of the terminal, and the helical antenna is arranged to be detachable from the housing of the main body of the terminal, such that the rod antenna is used as a stylus pen if needed. The helical antenna is screw-coupled to a fixing piece installed to the housing of the main body of the terminal. The helical antenna has a protrusion(311) protruded from the outer periphery of the helical antenna, and the housing has a groove(111) for loading the protrusion. Thus, the helical antenna is snap-fit structured so as to be attachable from the terminal.
