Thus, the insulation seat 600 is used to keep the insulation between the first metal base 310 and the low-frequency radiator 420, thereby improving the intermodulation index; meanwhile, the through hole of the insulating base 600 also prevents the electrical connection between the first metal base 310 and the second metal base 410 from being affected. Of course, the first metal base 310 may also be electrically connected to the low frequency radiator 420 by riveting or the like. The insulating base 600 may be made of an insulating material such as rubber or plastic.

On the basis of any of the above embodiments, the low frequency radiating unit 400 further includes a feeding component, and the feeding component is coupled with the low frequency radiator 420 for feeding. Therefore, the low-frequency radiator 420 is coupled and fed by the feeding component, so that the low-frequency radiator body does not need to be electroplated, and the production cost is further reduced. Meanwhile, the low-frequency radiator 420 and the high-frequency radiator 320 both adopt a coupling feed form, and the second metal base 410 is simultaneously used as a common ground point (a welding point of the first ground body and the second ground body) of the first radio frequency transmission member and the second radio frequency transmission member, thereby simplifying a feed structure of the dual-frequency radiation structure 100, avoiding excessive feed transfer, reducing welding spots, and improving assembly efficiency and intermodulation reaching rate.
