The invention provides a
router with an antenna built in and a middle frame structure thereof. The
router with the antenna built in comprises a first shell, a second shell, a
printed circuit board (PCB), an antenna, a
light guide column, and a middle frame structure, wherein the antenna is installed in the middle frame structure, the antenna is coupled with the PCB, the first shell and the secondshell enclose to form an
accommodation cavity, the outer side wall of the
accommodation cavity is an arc, the middle frame structure, the antenna, the
light guide column and the PCB are all accommodated in the
accommodation cavity, the first shell and the second shell are connected with the middle frame structure separately, a splicing seam is formed between the first shell and the second shell, the
peripheral wall of the
light guide column props against the inner side wall of the accommodation cavity and is exposed out of the splicing seam, a ribbon-shaped
light source is arranged on the surface, close to the annular light guide column, of the PCB in an annular manner, and the ribbon-shaped
light source faces the light guide column. Through adoption of
router with the antenna built in andthe middle frame structure thereof, the antenna is arranged in the router in diversified manners, the internal structure of the side, close to the accommodation cavity, of the two shells is simplified, a mold structure
processing the shell is simplified, so that the router shell is easier to process and realize.
