The invention discloses an antenna device and a smart watch, and belongs to the technical field of antennas. The antenna device comprises an annular carrier; and at least one spiral antenna, wherein each spiral antenna comprises a spiral antenna main body, the spiral antenna main body is wound on the annular carrier, and the screw pitch of the spiral antenna main body is smaller than the product of multiplying the diameter of the spiral antenna main body by a circumference ratio constant. According to the present invention, the miniaturization of the helical antenna is realized by controlling the screw pitch of the helical antenna main body and the diameter of the helical antenna main body, and more helical antennas can be arranged in the limited space, so that the switching of multiple antennas is realized, the SAR value of the antenna is reduced, the influence on a human body is reduced, and the antenna radiation direction requirements of various scenes can be met.
Description
technical field [0001] The present application belongs to the field of antenna technology, and in particular relates to an antenna device and a smart watch. Background technique [0002] With the continuous development of smart communication devices such as watches, more and more functions such as Bluetooth, WIFI, ECG monitoring, and blood pressure measurement are integrated into watches. Compared with traditional mechanical watches, smart watches not only provide a lot of convenience for people's daily life, but also gradually become an important part of the era of the Internet of Everything. [0003] However, compared with large-screen devices such as mobile phones, the design area of the watch is limited. Too large and heavy design will make the watch inconvenient to wear on the hand. As an important communication device of the smart watch, the space of the antenna is gradually replaced by other devices. The device is squeezed and reduced. Both 4G / 5G / WIFI and Bluetooth...
