Abstract: Disclosed are an antenna and a wearable electronic product. The antenna comprises a first antenna, a second antenna, and an isolation portion provided at the tail of the first antenna and the tail of the second antenna, and having a serpentine trace. Since the isolation portion has a serpentine trace, a path of a radiation current is extended, so that the current of the first antenna and the current of the second antenna can be attenuated to a greater extent under the action of the isolation portion, thereby improving the isolation between the first antenna and the second antenna. Therefore, by using this technical solution, the structure is simple, and the shape of an original radiation unit of the antenna does not need to be changed. Moreover, for a miniaturized wearable electronic product having a compact layout space, the isolation between two antennas can be significantly improved without occupying more space. According to this technical solution, an antenna mold does not need to be changed, and the debugging and test cycles are short. Finally, the added isolation portion increases the area (or length) of a main ground of the antenna, and therefore improves the efficiency of the antenna.
