Abstract

The invention discloses a watch antenna device and an electronic watch. The watch antenna device comprises a metal frame, a PCB and a mode separating circuit, wherein the PCB is provided with a metal layer and gaps for gap radiation between the PCB and the metal frame. The mode separating circuit is used for a radiation mode for exciting a radiation signal between the metal frame and the PCB and a degenerate mode circuit thereof and furthermore is connected between a signal input for feeding a signal to the metal frame and feeding points on the metal frame. Compared with the prior art, the watch antenna device provided by an embodiment of the invention can expand spectral bandwidth. The watch antenna device can be used as the antenna device of the intelligent watch.

Description

technical field [0001] The invention relates to antenna technology, more specifically, to a watch antenna device and an electronic watch. Background technique [0002] With the development of wireless communication technology, antenna technology is also developing rapidly. Devices supporting wireless communication are becoming more and more diverse. In recent years, wearable devices have been increasingly favored by users. Smart watches, in particular, are widely used and are becoming more and more popular among users. [0003] Usually, a smart watch is an accessory of a mobile device such as a mobile phone, and it cannot independently realize a call or exchange data with the Internet. But, for example, users expect smartwatches to be able to independently communicate wirelessly in order to track children's whereabouts, make emergency calls, and more. Therefore, people began to study smart watches that can carry out independent calls and Internet data exchange. [0004]...
