In the current mobile terminal market, low-frequency and mid-high-frequency antennas are usually distributed in different positions of the mobile terminal, or a main branch plus a parasitic loading method is used to realize the layout of the antenna. The current general antenna implementation method uses a single antenna layout, and due to the increasingly compact antenna layout space, the frequency switching scheme is more complex, and the design difficulty is greatly improved. At the same time, the antenna has a large attenuation in the mid-high frequency, and the efficiency is low, thereby causing the problem of poor antenna use effect.

[0038] Based on this, the present application hopes to provide an antenna scheme that can solve the above technical problems. The antenna frequency switching scheme of the present application is simple, can realize aperture tuning, and can effectively improve the antenna working efficiency and use effect.

As shown in Figure 5 and Figure 6 , it can be concluded that the peak efficiency of the antenna 100 at the first frequency is higher than -3dB, and the peak efficiency of the antenna 100 at the second frequency is higher than -5dB. It can be seen that the antenna structure of the present application greatly improves the efficiency of the antenna use.

[0074] In summary, in the antenna 100 and the mobile terminal 1000, when the antenna 100 works at the first frequency, the switch module 40 is selectively switched to be electrically connected with the second radiation part 20, the first radiation part 10 is electrically connected with the second radiation part 20 through the switch module 40, and the second radiation part 20 is connected to the system ground 50, so that the first radiation part 10 and the second radiation part 20 can be used as the first radiation unit of the antenna 100 for radiating or receiving the antenna signal of the first frequency; when the antenna 100 works at the second frequency, the switch module 40 is selectively switched to be electrically connected with the third radiation part 30, the first radiation part 10 is electrically connected with the third radiation part 30 through the switch module 40, and the third radiation part 30 is connected to the system ground 50, so that the first radiation part 10 and the third radiation part 30 can be used as the second radiation unit of the antenna 100 for radiating or receiving the antenna signal of the second frequency, realizing that the first radiation unit and the second radiation unit share the first radiation part 10, effectively saving the space for arranging the antenna 100 in the mobile terminal 1000. Moreover, the first radiation unit or the second radiation unit can be switched to receive or radiate the antenna signal when the antenna 100 works at different frequencies, that is, through the switching tuning mode, the antenna 100 has different tuning apertures, without switching the working frequency of the antenna through the high-order mode, avoiding the antenna signal attenuation caused by the high-order mode, thereby greatly improving the antenna efficiency, improving the use performance of the antenna at different working frequencies, and enhancing the use effect of the mobile terminal 1000.
