A novel GPS and BT dual-band antenna of a smart watch

Abstract

The invention discloses a novel GPS and BT dual-frequency antenna of a smart watch. The antenna includes a rear lid, A lid and annular metal exterior trim, A meter dial is arranged at that bottom of the ring-shaped metal appearance decorative member, An hour hand and a minute hand are arranged above the dial, the minute hand is arranged above the hour hand, A PCB board is arranged below the dial,A pogopin is welded on the PCB, and the pogo pin is connected with the antenna traces, the antenna traces are arranged on the inner wall of the ring-shaped metal appearance decorative part, the outertwo ends of the ring-shaped metal appearance decorative part are symmetrically provided with an appearance structural part, and the appearance structural part is internally provided with a watch bandcard slot. The invention designs a short section of line in the narrow space inside the smart watch, so that the antenna obtains better radiation efficiency in the working frequency band, and can be applied to the intelligent wearing equipment with smaller volume and metal structure of the external part. The antenna occupies a small space area, saves cost, and has simple design idea and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of smart watch antenna design, and in particular relates to a novel smart watch GPS and BT dual-frequency antenna. Background technique [0002] In recent years, with the rise and development of the Internet of Things (IoT) concept, more and more products and applications have joined the development trend of the Internet of Everything. Traditionally, a watch is only a wearable device that displays time and date. Today, in addition to these functions, a watch also has functions such as human heart rate detection, satellite navigation and positioning, wireless payment, voice communication, and data transmission. A watch with the above-mentioned multiple functions is called a smart watch. A smart watch can interact with people and things on the Internet. It needs to embed a wireless communication system in the watch, and the signal of the wireless communication system is transmitted / received through the antenna...

AI Technical Summary

Problems solved by technology

[0003] As a smart wearable device, the size of a smart watch is limited by its wearing properties, that is, in a relatively narrow space, in addition to placing a conventional time display module, a wireless communication system module also needs to be placed, which leads to a very complicated stacking layout. difficulty

The electrical size and length of the wireless communication antenna are related to the working frequency and wavelength of the antenna, and the performance of the antenna transmission signal has a great relationship with the surrounding environment of the antenna. Designing an antenna with good signal transmission on the Internet will face great challenges in the design work
