The present disclosure generally relates to a wearable device, and more particularly to a wearable device with an antenna.
A wearable device may have an appearance of a wrist watch, but has functions much more than telling time.
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. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially 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” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The present disclosure is described in relation to a wearable device. The wearable device can include a dial extending a shaft; two watch hand elements coupled to the shaft and configured to rotate 360 degrees in a plane about the shaft; an antenna element coupled to the shaft and configured to rotate 360 degrees in the same plane about the shaft; and a matching circuit matching with the antenna element.
The present disclosure is described further in relation to a wearable device. The wearable device can include a time display dial extending a shaft; two watch hand elements rotatably coupled to the shaft; an antenna element rotatably coupled to the shaft; and a matching circuit matching with the antenna element; wherein the two watch hand elements and the antenna element cooperatively show time of the wearable device.
The main body 10 can be substantially disc-shaped. The main body 10 has an outer face surface. The main body 10 has a side thereof coupled with an adjusting button 11 configured to adjust time of the wearable device 100. The main body 10 has the dial 20 mounted thereon. The dial 20 can be a time display dial. A shaft 21 extends out from the outer face surface of the main body 10. The shaft 21 can be substantially perpendicular to the outer face surface. The shaft 21 perpendicularly extends through the dial 20. The dial 20 can be positioned on the outer face surface of the main body 10 with the shaft 21 positioned in a center of the dial 20. The shaft 21 can be made from electric conducting materials.
The band 30 is attached to two opposite ends of the main body 10 and configured to attach the wearable device 100 to a user so that the outer face surface of the main body 10 is positioned facing away from the user. A buckle 40 is coupled to the band 30 for fixing the wearing device 100 to a hand of the user.
The watch hand elements 50 and the antenna element 60 are rotatably coupled to the shaft 21. The watch hand elements 50 include a first watch hand element and a second watch hand element. The first watch hand element and the second watch hand element can be an hour hand and a minute hand. The first watch hand element has a first end and a second end. The second watch hand element has a first end and a second end.
The antenna element 60 can be another watch hand element, i.e., a second hand of the wearable device 100. In at least one embodiment, the antenna element 60 can include a first end 61 and a second end 63 at two opposite sides of the shaft 21. A ratio of electrical capacitance of the first end 61 to the second end 63 can be direct proportional to a ratio of a length of the first end L1 to a length of the second end L2. A ratio of electrical inductance of the first end 61 to the second end 63 can be inverse proportional to the ratio of L1 to L2.
The first end of the first watch hand element and the first end of the second watch hand element of the watch hand elements 50 are attached to the shaft 21 so that the first watch hand element and the second watch hand element extend away from the shaft 21 substantially parallel to the outer face surface of the main body 10. The first end 61 of the antenna element 60 is attached to the shaft 21 so that the antenna element 60 extends away from the shaft 21 substantially parallel to the outer face surface of the main body 10.
Alternatively, the antenna element 60 can be an hour hand or a minute hand of the wearable device 100. The two watch hand elements 50 and the antenna element 60 cooperatively show time of the wearable device 100. Each of the first watch hand element, the second watch hand element, and the antenna element 60 are perpendicularly coupled to the shaft 21 and configured to rotate 360 degrees in a same plane about the shaft 21. The antenna element 60 can be made of material capable of wireless communications. In detail, the antenna element 60 can be made from electric conducting material.
To reduce or free from interferences with wireless communications of the antenna element 60, the watch hand elements 50 may be made of material that does not interfere with wireless communications. In one embodiment, the watch hand elements 50 may be made of plastic or coated with a non-conductive material. In detail, the watch hand elements 50 can be made from plastic material by non conductive vacuum metallization (NCVM).
In at least one embodiment, the antenna element 60 can work in two wireless communication frequency ranges. The first end 61 can work in a first wireless communication frequency range, the second end 63 can work in a second wireless communication frequency range, the first wireless communication frequency range can be different from the second wireless communication frequency range. In detail, the antenna element 60 can work in frequencies of Bluetooth and Wi-Fi. The antenna element 60 on the first end 61 communicates in frequencies in a range from 2400 MHz to 2484 MHz suitable for Bluetooth communications, and the antenna element 60 on the second end 63 communicates in frequencies in a range from 5200 MHz to 5800 MHz suitable for Wi-Fi communications. In other embodiments, the antenna element 60 may communicate in frequencies suitable for GPS. GSM, WCDMA, LTE communications.
The embodiments shown and described above are only examples. 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, including 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.
