Embodiment 1

[0028] According to an embodiment of the present invention, an antenna for improving low-frequency bandwidth is provided, which includes a GSM antenna 1, a GPS antenna 2, a WIFI antenna 3 and at least one antenna extension 4; at least one of the GPS antenna 2 and the WIFI antenna 3 is connected to a The antenna extension ground 4. After adding the design of the antenna extension 4, the low-frequency performance of the GSM antenna 2 is significantly improved. In this embodiment, the number of antenna extension grounds 4 is two, and the GPS antenna 2 and the WIFI antenna 3 are both connected to one antenna extension ground 4 . In practical applications, the number of the antenna extension 4 can also be one, which is connected to the GPS antenna 2 or to the WIFI antenna 3 .

[0029] In the antenna with improved low-frequency bandwidth in the embodiment of the present invention, after the design of the antenna extension 4 is added, the low-frequency performance of the GSM antenna...

Embodiment 2

[0045] According to an embodiment of the present invention, a method for preparing an antenna with improved low-frequency bandwidth is provided to obtain the antenna described in Embodiment 1. The method includes a pad printing process and a jet printing process.

[0046] Figure 5 Shown is a method for preparing an antenna using a TDP (Three Dimensional Printing, 3D printing) pad printing process, including the following steps:

[0047] S10, performing plasma treatment on the carrier to obtain the antenna carrier.

[0048] S20, providing an intermediate mold for making the antenna pattern, and printing conductive silver paste on the intermediate mold to fill the antenna pattern of the intermediate mold.

[0049] S30 , transfer the conductive silver paste filled in the antenna pattern to the surface of the plasma-treated antenna carrier by using a transfer glue head to form a pad printing layer, and obtain an intermediate.

[0050] S40, baking and solidifying the intermediat...

Abstract

The invention relates to the field of antennas, and concretely relates to an antenna for improving low-frequency bandwidth, and a mobile terminal. The antenna comprises a GSM antenna, a GPS antenna, a WIFI antenna and at least one antenna extension ground. And at least one of the GPS antenna and the WIFI antenna is connected with the antenna extension ground. According to the antenna for improving the low-frequency bandwidth and the mobile terminal, after the design of the antenna extension ground is added, the low-frequency performance of the GSM antenna is improved by 6 dB on the whole, and the antenna extension ground can remarkably improve the low-frequency performance of the GSM antenna.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna and a mobile terminal with improved low-frequency bandwidth. Background technique [0002] Antennas are found in most modern wireless devices such as mobile computers, mobile phones, tablets, smartphones, etc. [0003] A LOOP antenna that improves low-frequency bandwidth in the prior art, which includes a continuous wire coil that forms a LOOP antenna through shape routing, signal feed points and ground feed points that are respectively arranged at both ends of the wire coil. A square three-sided structure formed around the point, a rectangular loop structure connecting the square three-sided structure through the hypotenuse, the first extension branch extending from one side of the rectangular loop structure to the direction close to the signal feed point, and the bottom edge of the square three-sided structure There is a vertically upward second extending branch at the end, ...
