The problems that the module volume is increased and a placing space requirement on the antenna is high due to the antenna design of the traditional NB-IOT module are solved. The NB-IOT module comprises a NB-IOT module, a shield cover and an antenna; the shield cover is located above the NB-IOT module, and theshield cover and the antenna are in composite design to be used as a shield case as well as a radio frequency antenna; when being used as the shield case, the clutter interference of the surrounding environment can be shielded for the NB-IOT module so that the NB-IOT module can work stably; when being used as the radio frequency antenna, a good infinite radio frequency transceiving function can beprovided for the NB-IOT module, thereby guaranteeing the normal wireless communication function of the module; by adopting the composite design, the volume of the module cannot be increased, an operation of preparing a single placing area for the antenna is avoided, thereby realizing the miniaturized design of the module and facilitating the mounting on a terminal.
