Antenna and wearable electronic product

Abstract

The invention discloses an antenna and a wearable electronic product. The antenna comprises a first antenna, a second antenna and an isolation part arranged at the tail end of the first antenna and the tail end of the second antenna, wherein the isolation part has serpentine wiring. The isolation part has serpentine wiring so that the path of radiation current is prolonged, the current of the first antenna and the current of the second antenna can be attenuated to a large extent under the action of the isolation part, and the isolation degree of the first antenna and the second antenna is improved. It can be seen from this that the antenna is simple in structure without changing the shape of the original radiation unit of the antenna, and the isolation degree of the two antennas can be obviously improved without occupying too much space for the miniaturized wearable electronic product with tight layout space. The technical scheme does not need to change the antenna mold, and the debugging and testing periods are short. Finally, the additionally arranged isolation part increases the area (or length) of the main ground radiated by the antenna and improves the antenna efficiency.

Description

technical field [0001] The invention relates to the technical field of antenna isolation, in particular to an antenna and a wearable electronic product. Background technique [0002] Wearable electronic products, such as smart watches and smart bracelets, are widely used in people's lives. Wearable devices usually need to interact with other terminal devices to realize corresponding functions. Therefore, multiple frequency band antennas need to be installed on wearable devices. [0003] For wearable devices, the size is usually small, and external antennas are rarely used, and built-in antennas are generally used, which makes the product highly integrated. Due to the small size of the wearable device itself and the small internal space, when two antennas are arranged in it, the isolation between the antennas is a problem that cannot be ignored. [0004] In order to improve the isolation of the antenna, in the prior art, the shape of the radiation element of the antenna may...

AI Technical Summary

Problems solved by technology

Whether changing the shape of the antenna's radiating element or changing the grounding position of the antenna's feed point requires enough space to be realized, which is obviously not suitable for application in miniaturized wearable electronic products. Therefore, the improvement effect of the above two methods not obvious
