PURPOSE: A wireless modem in which an antenna can be moved is provided to obtain the optimum radio wave receiving sensibility by separating an antenna region from a PCB of a wireless LAN(Local Area Network) modem and freely adjusting the direction of an antenna. CONSTITUTION: A cylindrical bridge is connected so that it is possible for an antenna(205) to be rotated. Cylindrical bridges(200a,200b) are used for connecting a body to an antenna expanding board(215). Two cylinders are connected to the cylindrical bridges(200a,200b) on the same axis, and the cylindrical bridges(200a,200b) are connected to be rotated each other in a vertical direction of the axis.
