Problems solved by technology

[0004] In the existing watch antenna, since the performance of the antenna is related to the width of the gap between the first gap and the metal shielding layer of the display screen, the frequency band of the antenna covers the position of the connecting part of the parasitic part, the inductance value of the inductance in the connecting part The size, the grounding part of the antenna radiation body and the position of the feeding part are all related, and the implementation is relatively complicated

Embodiment Construction

[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0028] see figure 1 with figure 2 , the present invention proposes a watch antenna, comprising at least:

[0029] A slot 2 on the metal watch case 1, a feeder part 3 on the slot 2, a PCB 6 with a transmitting circuit and a receiving circuit.

[0030] Wherein, the slot 2 is a non-metallic material, and the absolute value of the difference between the length of the slot 2 and half of the central wavelength is less than or equal to the preset threshold; The feeder part on the upper part is connected and connected with one side of the slot 2.

Abstract

The invention discloses a watch antenna and a watch. The watch antenna at least comprises a gap formed in a metal watch shell, a feed part positioned on the gap, and a printed circuit board (PCB) with a transmitting circuit and a receiving circuit, wherein the gap adopts a non-metallic material; the absolute value of the difference value between the length of the gap and half of a central wavelength is less than or equal to a preset threshold value; and the feed part positioned on the gap is connected with a feed part on the PCB through a radio frequency cable, and connected with one edge of the gap. By adoption of the scheme, the antenna is realized through the gap in the metal watch shell; the bandwidth of the antenna is only associated with the position of the feed part on the gap, so that the performance of the antenna is only associated with the position of the gap in the metal watch shell and the length of the gap; and therefore, the antenna is realized simply.

Description

technical field [0001] The invention relates to the field of wearable devices, in particular to a watch antenna and a watch. Background technique [0002] Smart wearable devices are entering people's lives. People's requirements for product experience are getting higher and higher, and all-metal watches have a good texture, which is the general trend of the development of wearable devices. [0003] Existing watch antennas include: a printed circuit board (PCB, Printed Circuit Board), connecting parts and a metal frame used as the antenna radiation body; wherein, the metal frame is arranged around the PCB board, and a The first slit, the metal frame is also provided with a feeder part and a grounding part connected to the PCB board through the first slit; the metal shielding layer of the display screen is suspended on the PCB board, and the metal shielding layer of the display screen is connected to the PCB board through the connecting part The connection is grounded, a sec...
