The present disclosure provides an electronic apparatus including a main body, a sliding seat, a middle frame and four first antenna radiators. The main body may have a receiving space defined therein. An opening may be formed in the main body to communicate with the receiving space such that the receiving space can be communicated outside via the opening. The sliding seat may be received in the receiving space and movably connected to the main body such that the sliding seat can have a capability of being moved out from or retracted into the receiving space via the opening. The middle frame may be received in the receiving space. Four first antenna radiators may be disposed on the middle frame and the sliding seat respectively. The four first antenna radiators may have a capability of operating at a first frequency band.
