Structure for supporting antenna

The invention relates to a structure for supporting an antenna used in a portable terminal. Although the invention has been developed with the intention of applying the result thereof to a portable terminal such as a cellular telephone, the invention can be widely applied to various appliances using the antenna. A structure for supporting an antenna is composed of an antenna-supporting member which is formed under a radiator and shaped into a cylinder, an antenna-inserting portion which includes the first cylindrical space for accommodating the antenna-supporting member, locking claws which are connected with a lower end of the antenna-supporting member and interlocked with a lower edge of an inner wall of the first cylindrical space, and a rubber bush which includes a through hole, through which the antenna-supporting member passes, and is inserted between the radiator and the antenna-supporting member. An upper part of the antenna-inserting portion includes the second cylindrical space, which is concentric with the first cylindrical space and has an internal diameter larger than that of the first cylindrical space, and a lower part of the rubber bush fits into the second cylindrical space.
