Disclosed is an antenna using a slit of which length can be controlled. Embodiments of the present invention are to provide an antenna which is formed inside a metal case by embedding dielectrics into multi-stage slits arranged in the metal case. The antenna according to an embodiment of the invention comprises: a feeding line which is connected to a ground pad connected to a case, and a feeding pad to receive a signal for the feeding from a PCB; a radiator which is formed on the case and comprises one or more slits wherein a dielectric is embedded; and a plurality of switching terminals to control the resonant frequency of the slit. |
