The present invention relates to an integration module system of millimeter-wave and non-millimeter-wave antennas and an electronic apparatus, the system comprising a millimeter-wave antenna module and a non-millimeter-wave environment, the millimeter-wave antenna module forming a communication connection with the non-millimeter-wave environment for realizing reusing of the millimeter-wave antenna module to achieve a function of non-millimeter-wave antenna(s). The present invention proposes directly reusing a millimeter-wave antenna module, which is designed so that this module also has an antenna function of a non-millimeter-wave module, while an individual module's own volume does not need to be increased, and the module itself does not need to have additionally-added antenna traces, that is, with the same volume, a function of non-millimeter-wave antenna(s) may be further added. Therefore, it obviously helps to avoid an increase of the device's volume and improve compactness of the system and system design.
