Problems solved by technology

Therefore, the existing technical solutions are not compatible with 2G GSM900, GSM1800, 3G WCDMAB1 2100 and other frequency bands on the same wire at the same time
Moreover, the products of the existing technical solutions have strong radiation to the human body, limited communication functions, and low performance; some smart watches directly cancel the 2G / 3G communication function in order to improve user experience, and users cannot directly communicate with the outside world in real time with such smart watches. Communication, the user acceptance of such products is not high

Abstract

The invention provides a multi-band antenna and a smart watch employing the multi-band antenna. The multi-band antenna comprises a radiation part, a grounding point and a feeding point, wherein the grounding point and the feeding point are connected to the radiation part separately; the radiation part comprises a first radiation part extending outside from the feeding point, a second radiation part connected to the first radiation part and a third radiation part; and the third radiation part is parasitized from the first radiation part or the second radiation part and is connected to the grounding point. The smart watch can be compatible with the multi-band antenna for 2G / 3G communication in a limited space design; a user can communicate and access the Internet in real time; the measures of reducing radiation to a human body are taken into account by employing the routing layout of the antenna; and the requirements of a product on electromagnetic radiation SAR to the human body are met while the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of antennas and watches, in particular to a multi-frequency antenna and a smart watch using the multi-frequency antenna. Background technique [0002] In the wireless communication process, the antenna is an essential and important element. With the miniaturization of communication equipment, it is inevitable that the antenna design must be miniaturized accordingly. With the maturity and wide application of 3G / 4G networks and the perfection of 5G technology, the requirement for adding communication functions to small smart devices is increasing, and the requirements for communication quality are getting higher and higher, represented by smart watches How to integrate a mature 2G communication antenna and a widely used 3G communication antenna in a limited space has become a problem for designers. [0003] At present, smart watches are often equipped with multiple antennas to support various communication f...
