Terminal device

A terminal device, comprising a radiating body of a communication antenna, a millimeter-wave antenna array being disposed on the radiating body;

• wherein
• the radiating body is a metal frame of the terminal device, at least two slots are disposed in a side of the metal frame to form the millimeter-wave antenna array;
• at least two antenna feedpoints are disposed on an inner side wall of the metal frame, and different antenna feedpoints in the at least two antenna feedpoints are disposed on side edges of different slots;
• the terminal device further comprises a signal reflection wall disposed inside the terminal device, a gap exists between the signal reflection wall and the at least two slots, and the signal reflection wall is formed by a metal wall of a battery chamber of the terminal device;
• the battery chamber is a structure accommodating a battery of the terminal device, the metal frame and the signal reflection wall are both electrically connected to a ground plate of the terminal device, and the signal reflecting wall is disposed opposite to the at least two slots.
