In an embodiment, as shown in FIG. 1, the number of the branch antenna body 23 is two, including a first branch antenna body 231 and a second branch antenna body 232, and the first branch antenna body 231 is disposed at all On the first surface S1 of the antenna support 22, the second branch antenna body 232 is disposed on the second surface S2 of the antenna support 22, the first branch antenna body 231 and the second branch antenna body 232 Form a coupled antenna.

Further, as shown in FIG. 2, a feeding point F1 is provided on the second branch antenna body 232, and the feeding point F1 separates the second branch antenna body 232 into a first branch part B1 and a second branch part B1. The branch part B2, the first branch part B1 is used to support the transmission and reception of the antenna signal of the first frequency, and the second branch part B2 is coupled with the first branch antenna body 231 to support the transmission and reception of the antenna signal of the second frequency.

That is, the part between one end D1 of the second branch antenna body 232 and the feeding point F1 is the first branch part B1, and the other end D2 of the second branch antenna body 232 is between the feeding point F1 The part is the second branch part B2. The feeding point F1 is used for connecting with a feed source and used for feeding. The feeding point F1 substantially divides the second branch antenna body 232 into the first branch part B1 and the second branch part B2 These two parts.
