Multi-band mobile phone antenna

Abstract

The invention discloses a multi-band mobile phone antenna, which is used for solving the problems that the use environment and the use condition of the multi-band mobile phone antenna cannot be known in real time, and the signal connection of the multi-band mobile phone antenna cannot be screened and diagnosed. The device comprises a network diagnosis module, a network screening module, a fault analysis module and an environment monitoring module, wherein the environment monitoring module is used for carrying out safety monitoring on the use environment of the mobile phone antenna body, and the fault analysis module receives an environment abnormal signal sent by the server and is used for carrying out fault diagnosis on the mobile phone antenna body in combination with the sensing unit and the screening unit; the network screening module is used for screening the network of the mobile phone antenna body, the network diagnosis module is used for carrying out network diagnosis on the network of the mobile phone antenna body. According to the invention, the use environment and the use condition of the multi-band mobile phone antenna can be conveniently known in real time, and the connection network of the multi-band mobile phone antenna can be screened and diagnosed.

Description

technical field

[0001] The invention belongs to the field of mobile phone accessories and relates to mobile phone antenna technology, in particular to a multi-band mobile phone antenna. Background technique

[0002] The mobile phone antenna is the device used to receive signals on the mobile phone. The old mobile phone has a convex antenna, and most of the new mobile phones are hidden in the fuselage. This type of antenna is mainly inside the phone, and the inside of the phone cannot be seen from the outside. The mobile phone antenna is a standing wave antenna. If the impedance of the antenna does not match, it will cause a large number of signal reflections, which will reduce the radiation efficiency of the antenna. 6, the breakdown voltage of the front end of the mobile phone will be reduced to 1 / 6 of the original, and the power capacity will be reduced. The impact of mobile phone antenna standing wave on antenna efficiency cannot be ignored. The standing wave requireme...
