The magnetic portion may be coated with an electrically conductive material, and one end of the built-in antenna and one end of the external antenna may include a metal portion, and the internal antenna may be electrically connected to a feed portion formed on one side of the substrate. When the external antenna is coupled with the magnetic portion, the internal antenna, the magnetic portion, and the external antenna are located on a virtual straight line perpendicular to the substrate, and the external antenna, the magnetic portion, The built-in antenna, and the power supply unit may be electrically connected.

The dual antenna for a terminal according to the present invention can simplify the antenna structure by electrically connecting two antennas to one feeder.

In addition, in the dual antenna for a terminal device according to the present invention, since the external antenna is coupled to the terminal device by magnetic attraction, foreign matter is not formed between the antenna and the terminal device, have.
