A portable terminal for DMB(Digital Multimedia Broadcasting) reception is provided to enable a main antenna and a terminal signal line to have different grounds, thereby increasing DMB reception sensitivity of the portable terminal for DMB reception. A main antenna(148) and a terminal signal line(154) are connected to a coupler(152). A DMB module(146) processes signals inputted through the terminal signal line and the main antenna by being connected to the coupler. A terminal port(156) is connected to the terminal signal line. Each of the main antenna and the terminal signal line has different grounds, respectively. The coupler and the terminal port are mounted on a PCB(Printed Circuit Board)(150). The terminal signal line is formed by an internal layer circuit of the PCB. |
