Patent Application
20170141459
This application claims priority to Chinese Patent Application No. 201510774563.0 filed on Nov. 13, 2015, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to an antenna module and a wearable device using same.
Wearable devices, such as smart watches, bracelets, generally have a wireless communication function and include an antenna for establishing a wireless communication connection with other electronic devices, such as mobile phones, or personal digital assistants, for example. Additionally, many wearable devices further employ metal housings for improving heat dissipation or other purposes.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details.
In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure is described in relation to an antenna module and a wearable device using same.
In at least one embodiment, the main body 11 is substantially circular. The main body 11 is made of conductive material, for example, metallic material. It can be understood that the main body 11 can also have other shapes, for example, square or oval. The main body 11 includes a bottom planar wall 111 and a peripheral wall 113. The peripheral wall 113 is positioned at a periphery of the bottom planar wall 111. The peripheral wall 113 and the bottom planar wall 111 cooperatively form a dish-shaped receiving space 115.
In at least one embodiment, the baseboard 13 includes a feed point 133. The feed point 133 is electrically connected to the main body 11 through a connecting portion, for example, a terminal or the like. The feed point 133 is further electrically connected to a signal source (not shown) for feeding current to the antenna module 100.
In at least one embodiment, the ground portion 15 is substantially an arcuate frame. The ground portion 15 is made of conductive material and is grounded. The free ends of the ground portion 15 define a space 151 therebetween. The ground portion 15 is positioned in the first gap 131 and is configured to connect the main body 11 to the baseboard 13. Additionally, due to the ground portion 15 defining the space 151, when the ground portion 15 is positioned in the first gap 131, an area of the first gap 131 corresponding to the space 151 is empty, thereby forming a second gap 153. The second gap 153 is substantially arcuate. Then, the antenna module 100 can activate a working frequency band through the second gap 153. In at least one embodiment, the antenna module 100 can work at Bluetooth (BT) frequency band. In other embodiments, the antenna module 100 can work at other frequency bands.
The housing 17 is a portion of the wearable device 200 contacting with a user. The housing 17 has a shape and a structure corresponding to the main body 11. For example, the housing 17 can be circular or square. The housing 17 is assembled to the main body 11 through a latching structure, for example, screw. The housing 17 seals the receiving space 115 and receives the baseboard 13 and the ground portion 15 together with the main body 11.
In at least one embodiment, the housing 17 includes a first housing 171 and a second housing 173 surrounding the first housing 171. In at least one embodiment, the first housing 171 is made of conductive material (for example, metallic material) or insulating material (for example, palastic or ceramic). The second housing 173 is made of insulating material. Generally, when an antenna is used, the user is at a radiating area of the antenna, then, different portions of the user, for example, the head or the hands of the user will affect a radiating performance of the antenana. Then, when the first housing 171 is made of conductive material and the wearable device 200 is attached to the wrist of the uer, the first housing 171 mading of conductive material will shield an influence of the user on the antenna module 100, that is, an ininfluence of the user on the antenna module 100 can be decreased, and thereby a radiating performance of the antenna module 100 can be improved.
It can be understood that, in at least one embodiment, to obtain a better radiating performance, a width of the second housing 173 is larger than 1.5 mm. Additionally, the housing 17 can be electrically connected to the baseboard 13 (that is, the housing 17 is grounded), or the housing 17 is spaced and disconnected from the baseboard 13.
It can be understood that the baseboard 13 further includes a keep-out-zone 135. The purpose of the keep-out-zone 135 is to delineate an area on the baseboard 13 in which other electronic elements (such as a camera, a vibrator, a speaker, etc.) cannot be placed. A shape of the keep-out-zone 135 and a position of the keep-out-zone 135 on the baseboard 13 can be adjusted according to a need of the user. In at least one embodiment, the keep-out-zone 135 is positioned adjacent to the second gap 153.
As illustrated in
The display unit 21 can be a liquid crystal module (LCM) or the like. The display unit 21 is positioned at one surface of the main body 11 opposite to the housing 17. The display unit 21 is electrically connected to the baseboard 13. The battery 23 is received in the receiving space 115. The battery 23 is positioned between the baseboard 13 and the housing 17. The battery 23 is configured to supply power to the wearable device 200.
The watchband 25 is configured to attach the wearable device 200 to a user. In at least one embodiment, the watchband 25 includes two watchband portions 252. Each watchband portion 252 is made of insulating material, for example, leather. One end of the two watchband portions 252 are connected to each other. The other ends of the two watchband portions 252 are respectively assembled to two sides of the main body 11 through a latching structure (not shown), thereby the wearable device 200 can be firmly attached to a wrist of the user.
In view of
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of the antenna module and the wearable device. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, especially in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
