An apparatus of antenna with heat slug and its fabricating process are provided, in which the antenna with heat slug can be realized with a single sheet or double sheets of metal. A dual-band antenna module with a mask cover is taken as an example to realize the apparatus. Each single sheet of metal can be achieved by simply cutting and bending a metal plate. Thereby, it is a simple and low-cost fabricating process. In the known fabricating process of integrated circuit, the heat slug and the antenna can be combined in a module at the same step. Therefore, integrating the antenna with heat slug in a fabricating process needs not to develop a new process.
