[0038] It should be noted that by connecting the opposite ends of the second antenna body 20 to the first antenna body 10 and the third antenna body 30 respectively, and by making an angle between the first antenna body 10 and the second antenna body 20, and between a partial structure of the third antenna body 30 and the second antenna body 20, the structural design of the antenna 100 can be reasonable, and the performance of the antenna 100 can be improved without increasing the structural size of the antenna 100, so that the volume of the antenna 100 can be reduced while meeting the performance requirements of the antenna 100 to meet the needs of miniaturization of the antenna 100. In addition, such an arrangement can make the second antenna body 20 suspended on the mainboard, that is, the second antenna body 20 can be located outside the surface of the mainboard to reduce the influence of the mainboard on the electromagnetic waves radiated by the antenna 100. The antenna 100 proposed in this application has a large bandwidth and high radiation efficiency, which is conducive to reducing the volume of the antenna 100 and reducing the area of ​​the clearance zone.
