Description

Antenna and terminal

Technical Field

The invention relates to the technical field of communication, in particular to an antenna and a terminal.

Background

The electrostatic protection problem is always the key point of engineering design for terminals such as mobile phones and smart watches, and in addition, the GPS/Beidou system is most vulnerable to electrostatic attack. Due to the narrow operating band of GPS, surface acoustic wave filters (SAW) are often used on the radio frequency link for better performance. The filter has the advantages of high Q, high roll-off, narrow band and small volume; however, the working principle of the filter determines that the filter is not high-voltage resistant and is very easy to damage when being attacked by electrostatic discharge, thereby affecting the radio frequency performance of the GPS. Even ordinary post-stage components, such as amplifiers and chips, ESD protection is an important issue and may be damaged inadvertently.

Taking the GPS system which is most vulnerable to damage due to electrostatic attack as an example, from the perspective of the rf link, the main reason why SAW is attacked by electrostatic discharge is that the GPS antenna is attacked by electrostatic discharge. When the equipment is held by hands, electrostatic breakdown and conduction to the antenna may occur when the equipment is placed on a metal placing table with electrostatic charge. To protect against static electricity, it is best to provide a discharge circuit in the front stage of the filter, i.e. a direct current ground at a nearby location to bypass the pulse voltage to a large metal "ground". However, the conventional antistatic measures are still problematic, and the possibility of damage by static electricity still exists.
