Abstract: A mobile terminal includes: a terminal body having a display unit; a band connected with both ends of the terminal body; and an antenna radiator installed in the band.

Abstract: A flux cored wire for duplex stainless steel and a manufacturing method thereof are provided. The flux cored wire can include a sheath and a flux filled into the sheath. The flux cored wire comprises about 24.0-30.0 wt % Cr, about 7.0-10.5 wt % Ni, about 2.0-4.0 wt % Mo, about 0.10-2.50 wt % Cu, about 0.40-1.00 wt % Si, about 1.5-3.0 wt % Mn, about 0.10-0.30 wt % N compound (converted value of N), and the remainder including Fe and inevitable impurities on the basis of the total weight of the wire. The flux comprises about 6.50-12.00 wt % of TiO2+SiO2+ZrO2+Al2O3, about 0.10-0.50 wt % of Li2O+K2O+Na2O, about 0.10-2.00 wt % of the other oxides, and about 0.10-0.50 wt % of metal fluoride (converted value of F) on the basis of the total weight of the wire. The flux can be filled into the sheath at a ratio of about 26-35%.
