Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are presented.

First embodiment

As shown in fig. 3 and 4, the antenna assembly provided in the first embodiment of the present application includes a monopole antenna 30, a back cover 40 and a suspended antenna 50, where the monopole antenna 30 is used for being electrically connected to an electrical component of the intelligent terminal, such as a main board 61, and is disposed on an inner side surface of the back cover 40, that is, a side of the back cover 40 facing the main board 61; the suspended antenna 50 is disposed on an outer side surface of the back cover 40, that is, on a side of the back cover 40 away from the main board 61, and corresponds to a position of the monopole antenna 30.

In fig. 3, in order to reflect the positional relationship among the monopole antenna 30, the back cover 40, and the suspended antenna 50, the outer side view of the back cover 40, the side view of the positional relationship among the back cover 40, the monopole antenna 30, and the suspended antenna 50, and the inner side view of the back cover 40 are provided in this order from the left to the right, and the position of the monopole antenna 30 is shown in the form of a broken line in the outer side view of the back cover 40. The concentric circles in fig. 3 may be used to represent the camera 63 of the intelligent terminal. The above-described forms are also adopted in fig. 7 to 10.

In this embodiment, by arranging the monopole antenna 30 and the suspension antenna 50, and arranging the two antennas on the inner and outer sides of the back cover 40 respectively, the monopole antenna 30 is used for being electrically connected with an electrical device, such as the main board 61, and when the monopole antenna 30 is in operation, the monopole antenna 30 can be excited first, and the monopole antenna 30 can excite the suspension antenna 50 on the outer side of the back cover 40 in a coupling feed manner, so that signal transmission is realized. In this embodiment, the monopole antenna 30 is configured with the suspended antenna 50, where the monopole antenna 30 is disposed on the inner side surface of the back cover 40, and the suspended antenna 50 is disposed on the outer side surface of the back cover 40, so that the available space for antenna arrangement can be increased on the outer side surface of the back cover 40, and the space of the intelligent terminal can be better utilized.

Optionally, the size of the monopole antenna 30, the thickness of the back cover 40, the material of the back cover 40, and the size of the suspended antenna 50 may be designed according to the frequency band that the antenna assembly needs to support, so as to achieve the desired effect. The monopole antenna 30 and the suspended antenna 50 may be implemented by an LDS (Laser-Direct-structuring) process or other processes.

Optionally, in this embodiment, a feeding point 31 for electrically connecting with an electrical component, such as a feeding pin 611 on the main board 60, is provided on an upper end of the monopole antenna 30 (i.e., an upper end in the up-down direction in fig. 3), and when the back cover 40 is mounted on the smart terminal, the feeding point 31 on the monopole antenna 30 is electrically connected with the feeding pin 611 on the main board 61. In other words, the monopole antenna 30 is oriented toward an electrical component, such as the motherboard 61, to which it is connected, and the projection in the direction is at least partially incident on the electrical component. Since the monopole antenna 30 is disposed on the inner side surface of the back cover 40 and can directly contact with the main board 61, the monopole antenna can adopt a combination mode of the feeding pin 611 and the feeding point 31, and no additional LCP transmission line or coaxial line is required.

Optionally, in this embodiment, the monopole antenna 30 extends on the back cover 40 along the up-down direction of the back cover 40 (i.e. the up-down direction in fig. 3 is also equivalent to the length direction of the back cover 40), and a part of the projection of the monopole antenna 30 in the direction of the electrical component connected thereto falls on the electrical component, and another part falls outside the electrical component, so as to facilitate the layout of the peripheral components and prevent interference to the peripheral components. In other words, taking the main board 61 as an example, in the direction perpendicular to the plane of the back cover 40, the upper end of the monopole antenna 30 coincides with the position of the main board 61, and the lower end of the monopole antenna 30 extends out of the main board 61 to coincide with the position of other components, such as the battery 62.

Alternatively, in the present embodiment, the distance from the feeding point 31 of the monopole antenna 30 to the upper end of the back cover 40 is greater than the distance from the upper end of the suspended antenna 50 to the upper end of the back cover 40 and less than the distance from the lower end of the suspended antenna 50 to the upper end of the back cover 40 along the up-down direction of the back cover 40 (i.e., the up-down direction in fig. 3 is also equivalent to the length direction of the back cover 40). In other words, the projection of the feeding point 31 of the monopole antenna 30 toward the floating antenna 50 is located between the upper end and the lower end of the floating antenna 50 in the up-down direction of the back cover 40, which can facilitate the coupling of the monopole antenna 30 and the floating antenna 50.

Alternatively, in the present embodiment, the monopole antenna 30 and the suspended antenna 50 may be elongated, and the central axes of the monopole antenna 30 and the suspended antenna 50 are located on the same plane perpendicular to the back cover 40.

Alternatively, the width of the suspended antenna 50 (i.e., the width of the suspended antenna 50 in the left-right direction in fig. 3) is not greater than the width of the monopole antenna 30 (i.e., the width of the monopole antenna 30 in the left-right direction in fig. 3).

Second embodiment

As shown in fig. 5, the second embodiment of the present application has substantially the same structure as the first embodiment, except that, in this embodiment, since the suspended antenna 50 is located outside the back cover 40, a protective layer 70 is further covered outside the suspended antenna 50 to protect the suspended antenna 50.

Third embodiment

As shown in fig. 6, the third embodiment of the present application has substantially the same structure as the first embodiment, but is different in that in the present embodiment, a receiving groove 41 is provided on an outer side surface of the back cover 40, and a suspension antenna 50 and a protection layer 70 are sequentially provided in the receiving groove 41 in a direction from a bottom of the receiving groove 41 to a top of the receiving groove 41. By the arrangement of the above structure, the height of the suspended antenna 50 protruding outside the back cover 40 can be reduced.

Alternatively, the upper surface of the protective layer 70 is flush with the surface of the outside of the back cover 40.

Fourth embodiment

As shown in fig. 7, the fourth embodiment of the present application has substantially the same structure as the first embodiment, except that in this embodiment, the shape of the suspended antenna 50 may not be a long strip, and may be a sheet, and the width of the suspended antenna 50 is larger than the width of the monopole antenna 30.

Optionally, a hollowed pattern 53, such as a logo of an intelligent terminal, may be disposed on the suspension antenna 50, so as to achieve a better appearance effect while achieving the function of the antenna.

Alternatively, the hollowed pattern 53 may be X-shaped.

Fifth embodiment

As shown in fig. 8, the fifth embodiment of the present application is basically the same as the fourth embodiment, except that the hollowed pattern 53 of the sheet-like suspended antenna 50 may be T-shaped.

In other words, the hollowed pattern 53 of the sheet-like suspended antenna 50 may be provided as needed, and is not limited.

Sixth embodiment

It will be appreciated that in other embodiments, the parameters may be adjusted to enable the antenna assembly to support other frequency bands, or to enable the first prong 51 to support the same frequency band as the second prong 52.

Optionally, in this embodiment, hollowed patterns may be further disposed on the first branch portion 51 and the second branch portion 52, so as to improve the appearance on the premise of not affecting the performance of the antenna assembly.
