A multistage antenna for a mobile communication terminal with a flexible helical coil unit is provided to prevent deformation and damage due to external shocks by an antenna wire and an antenna tube. A multistage antenna for a mobile communication terminal with a flexible helical coil unit includes a holder, a helical coil support, an upper coil support, a stopper, a wire stopper, and a wire fixing unit(20). The holder has a large cylindrical concave spring. The helical coil support supports a helical coil wound around a helical coil bobbin at a lower part, and fixes an antenna tube(6) at an upper part. The upper coil support has a small cylindrical concave spring, and supports the helical coil. The stopper is closely inserted into the large cylindrical concave spring of the holder, and fixes the antenna tube(6) at a lower part. The wire stopper fixes an antenna wire(4) at a lower part, and is closely inserted into the small cylindrical concave spring. The wire fixing unit(20) is inserted into an antenna head(3), and fixes an upper part of the antenna wire(4).
