Embodiment Construction

[0024] Combining the aforementioned background technology, it can be seen that in the antenna design of wearable devices, the design space of the antenna is generally small, and the space of the reference ground is limited, which makes the design of wearable device antennas in lower frequency bands difficult. In order to overcome this difficulty, the present invention provides an antenna device for a wearable device and the wearable device.

[0025] Specific embodiments of the antenna device for a wearable device and the wearable device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0026] see figure 1 , figure 1 What is shown is a schematic structural diagram of an antenna device for a wearable device provided by an embodiment of the present invention. combine figure 1 It can be seen that the antenna device includes: a PCB (Printed Circuit Board, printed circuit board) board 1 , a first antenna 2 , a secon...

Abstract

The invention discloses an antenna apparatus for a wearable device and a wearable device. The antenna apparatus is composed of a first antenna, a second antenna, a first change-over switch, and a radio frequency unit. The first change-over switch and the radio frequency unit are arranged on a PCB; and one end of the first change-over switch is connected with the second antenna and the other end isconnected to the radio frequency unit or a reference ground on the PCB in a switchable manner. If the first antenna works at a frequency band less than a preset threshold, the radio frequency unit isused for controlling the other end of the first change-over switch to be switched to the reference ground. And the radio frequency unit is also used for controlling the other end of the first change-over switch to be switched to the radio frequency unit when receiving an instruction for indicating the second antenna to receive and send signals. According to the antenna apparatus, the second antenna in a non-working state is used as an extended reference ground of the first antenna in a working state, so that the receiving and sending performances for signals with the frequency bands less thanthe preset threshold of the first antenna are improved.

Description

technical field [0001] The present invention relates to the technical field of antennas for wearable devices, in particular to an antenna device for wearable devices and the wearable device. Background technique [0002] With the development of smart mobile terminal technology, the form of mobile terminals has expanded from traditional mobile phones to wearable devices and other mobile terminals whose internal circuit design space is smaller than that of traditional mobile phones, such as smart watches. At the same time, with the increasing demand for functional compatibility in mobile terminals and the expansion of data connection functions, requirements such as the number of antennas required by mobile terminals and the frequency bands of antennas are also increasing. [0003] Usually, in the antenna design of a mobile terminal, in order to ensure that the antenna has good signal transceiving performance, it is necessary to design the area of ​​the reference ground of the ...
