Protective shell with cell phone signal enhancement function

Abstract

The invention relates to a special protection shell for IPhone, in particular to a protective shell with an IPhone signal enhancement function. The protective shell with the IPhone signal enhancement function comprises a lower cover and an upper cover clamped with the lower cover in a matching manner, wherein each of the inner faces of the lower cover and the upper cover are composited with a layer of sticky damping layer, a functional antenna is arranged between the lower cover and the sticky damping layer and is arranged on a lower left corner of the lower cover, and the functional antenna is a bent sheet body and has the thickness H being not smaller than 0.17mm and not more than 0.23mm; the distance between the functional antenna and the inner wall of the sticky damping layer is M which is not smaller than 0.35mm and not more than 0.45mm; and a functional slot is formed in the functional antenna, and a through hole is formed in a part, jointing with the functional antenna, of the sticky damping layer. The protection shell can be used to enhance the cell phone signals by 30%, and can be utilized to effectively solve the problem of signal attenuation generated when some cell phone users make calls at places (such as signal-shielding rooms, tunnels, and residential areas or commercial districts with high-rise buildings, and other remote places with weak signals) with weaker signals, and enhance the signal intensity to guarantee the quality of connection.

Description

technical field [0001] The invention relates to a protective case specially used for mobile phones of IPhone 4 / 4S and above models, in particular to an IPhone mobile phone signal enhancement protective case. Background technique [0002] At present, IPhone 4 / 4S and above mobile phones are popular in various groups of people, and it is well known that the external antenna of IPhone 4 / 4S and above mobile phones surrounds the whole body of the mobile phone, and in some signal In relatively shielded rooms, residential areas or commercial areas with high-rise buildings, tunnels, and some weaker remote areas, the signal received by the mobile phone will attenuate, affecting people's calls and other operations, and bringing a lot of inconvenience to people. At the same time, When the user answers the phone, the signal reception will be affected to varying degrees due to the different holding angles. Contents of the invention [0003] 1.
