Millimeter wave antenna suitable for 5G terminal

The invention relates to the technical field of 5G millimeter waves, and discloses a millimeter wave antenna suitable for a 5G terminal, which comprises a mobile phone bottom shell, a circuit substrate is mounted in the mobile phone bottom shell, a slot is formed in the inner top wall of the mobile phone bottom shell, and a millimeter wave antenna module is movably connected in the slot. The bottom of the back surface of the millimeter wave antenna module is movably connected with the top of the front surface of the circuit substrate. According to the millimeter wave antenna suitable for the 5G terminal, when the millimeter wave antenna module is damaged, the screws on the two sides of the U-shaped frames are screwed out, so that the two U-shaped frames around the mobile phone bottom shell are disassembled, and the opposite sides of the two insertion blocks are inclined planes and are matched with the gaps on the two sides of the millimeter wave antenna module; the millimeter wave antenna module can be pulled
