Watch antenna and intelligent watch with GPS (global position system) and Bluetooth functions

Abstract

The invention provides a watch antenna and an intelligent watch with GPS (global position system) and Bluetooth functions. The watch antenna comprises a PCB (printed circuit board), a connecting part and a metal edge frame, wherein the metal edge frame is used as an antenna radiation body, and is arranged around the PCB, a first gap is formed between the metal edge frame and the PCB, the metal edge frame is provided with an electric feeding part and a grounding part which are connected with the PCB through the first gap, a metal shielding layer of a display screen is suspended above the PCB, the metal shielding layer and the PCB are connected and grounded through the connecting part, a second gap is formed between the metal shielding layer of the display screen and the metal edge frame, and the metal shielding layer of the display screen and the connecting part form a parasitic part. The watch antenna has the advantages that the double-frequency resonance is generated by the gap between the metal edge frame and the PCB of the watch, and the intelligent watch with the GPS and Bluetooth functions is designed.

Description

technical field [0001] The present invention relates to a smart watch antenna using the metal frame of the watch as an antenna, in particular to a watch antenna and a smart watch covering GPS and Bluetooth. Background technique [0002] Wearable smart devices are a new development direction of electronic consumer products. At present, there are a variety of trend-leading smart watches on the market, such as moto360 and other products. In order to improve the design of the appearance and maintain the strength of the shell, aluminum, magnesium, etc. are used Metal forms the frame of the smart watch, and its round metal frame can attract many consumers. Moreover, the display screen installed on the smart watch is usually provided with a metal shielding layer, and the metal shielding layer of the display screen can provide a good interference shielding function for the display effect of the display screen. However, it is precisely because of the existence of the metal frame and...

Problems solved by technology

[0003] At present, its wireless communication part only has Bluetooth function and does not have GPS function, which brings great regret to consumers.

At the same time, the metal watch frame poses a big challenge to the antenna design of smart watches. Traditional inverted F-shaped antennas, inverted L-shaped antennas, monopole antennas, and loop antennas are difficult to cover GPS and Bluetooth frequency bands at the same time.
