Abstract

The utility model discloses a mobile terminal which comprises a main base board and an antenna module connected with the main base board, wherein the antenna module is connected with the main base board by a connection wire with the length less than or equal to 2 mm. Because the antenna module of the utility model is connected with the main base board by the connection wire with the length less than or equal to 2 mm, the resonance formed with an antenna in the antenna module has short grounding distance, and the resonance energy can be converted into effective energy. Consequently, the influence on the other adjacent antennas by the antenna module is effectively reduced.

Description

a mobile terminal

technical field

The utility model relates to the field of mobile communication, in particular to a mobile terminal.

Background technique

Mobile phones are currently the most commonly used electronic equipment for people. Adding GPS positioning functions to mobile phones has increasingly become a development trend. At present, mobile phones usually have at least one mobile communication antenna (dual-mode mobile phones and diversity reception mobile phones have two communication antennas, and Bluetooth antennas have also become standard configurations, and more and more WiFi, FM, and mobile TV antennas are introduced into the mobile phone. Mobile phone. The overall volume of the mobile phone cannot be too large, and the shape design tends to be more and more miniaturized. Therefore, if the GPS antenna is added to the mobile phone, there will often be other antennas close to the GPS antenna. The working characteristics and structural characteristics will greatly affect the working performance of adjacent large lines.

Utility model content

The purpose of the utility model is to provide a mobile terminal, so that the influence among multiple antennas inside it can be reduced.

In order to solve the above-mentioned technical problems, the utility model proposes a mobile terminal, including a main substrate and an antenna module connected to the main substrate, and the antenna module is connected to the ground of the main substrate through a connection wire less than or equal to 2mm.

Wherein, the antenna module includes an antenna and a substrate, the antenna is arranged on the substrate, and the ground of the substrate is connected to the ground of the main substrate through the connection line less than or equal to 2 mm.

Wherein, the mobile terminal further includes other antennas, and the distance between the other antennas and the antennas in the antenna module is greater than or equal to 3mm.

Preferably, the antenna module is a GPS antenna module.

Preferably, the connecting wire is a metal sheet.

In the present utility model, since the antenna module is connected to the ground of the main substrate through a connecting wire less than or equal to 2mm, compared with other antennas, the resonance formed with the antenna in the antenna module is because the grounding distance is short , so that this part of resonance energy becomes effective energy, thereby effectively reducing the impact of the antenna module on other adjacent antennas.

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is elaborated.

Referring to Fig. 1, it illustrates a schematic structural view of an embodiment of the present utility model. As shown in the figure, it includes a main substrate 101 , a coaxial cable connector 102 , a coaxial cable 103 , a metal sheet 106 , a GSM antenna 107 and a GPS antenna module 2 .

The GPS antenna module 2 includes a substrate 104 and an antenna 105 .

Wherein, the GPS antenna 105 is located above the main substrate 101 of the mobile terminal, and is perpendicular to the main substrate 101 . The GPS antenna 105 is connected to the main substrate 101 through a radio frequency coaxial cable 103 and a coaxial cable connector 102 .

The GSM antenna 107 is also disposed on the top of the main substrate 101 , and is located on the left side of the GPS antenna 105 and adjacent to the GPS antenna 105 .

The substrate 104 in the GPS antenna module 2 has a large area of metal ground on it, which is used as a signal reflection surface of the GPS antenna 105 . The metal ground of the substrate 104 is connected to the metal ground of the main substrate 101 through the radio frequency coaxial line 103 .

For the adjacent GSM antenna 107 , due to the existence of the metal ground of the substrate 104 , it not only forms a resonance with the main substrate 101 , but also forms a resonance with the substrate 104 in the GPS antenna module 2 during operation. In the prior art, since there is no metal sheet 106, only the radio frequency coaxial line 103 is included, and the length of the radio frequency coaxial line 103 is often more than 20 mm. For the adjacent GSM antenna 107, it is different from the GPS antenna The resonance formed by 105, because the grounding distance is too long, will make this part of the resonance energy become invalid energy.

However, in this embodiment, the substrate 104 is directly connected to the main substrate 101 by setting the metal elastic piece 106 so that the electrical length between the metal ground of the substrate 104 of the GPS antenna 105 and the metal ground of the main substrate 101 of the mobile terminal is as short as possible. Like this, for the adjacent GSM antenna 107, the resonance formed with the GPS antenna 105, because the grounding distance is short, makes this part of resonance energy become effective energy, thereby effectively solving the problem of the GPS antenna 105 to the adjacent GSM antenna 107. In addition, a distance of at least 3 mm should be kept between the GFS antenna 101 and the adjacent GSM antenna 107 .

Wherein, in a preferred embodiment of the present invention, the length of the metal sheet 106 is less than or equal to 2mm.

In addition, it should be noted that the above-mentioned two antennas (GSM antenna and GPS antenna) are only one embodiment of the present utility model, and the GSM antenna can also be other antennas, such as CDMA antenna, 3G antenna, and the GPS antenna The antenna can also be any other antenna that requires a reflective surface.

The metal sheet is not limited to the shape of a sheet, and it is essentially a short connection line, so it can be in any form of connection line, and the utility model is not limited thereto.

What is disclosed above is only a preferred embodiment of the utility model, and of course it cannot limit the scope of rights of the utility model. Therefore, the equivalent changes made according to the claims of the utility model are still covered by the utility model. scope.
