As shown in fig. 1, fig. 1 shows a schematic structural diagram of an antenna according to an embodiment of the present disclosure. The disclosed embodiment provides an antenna 10, including: a first antenna 11 and a second antenna 12 which are not connected with each other, and a barrier 13 arranged between the first antenna 11 and the second antenna 12; wherein the barrier 13 is a conductive barrier structure between the first antenna 11 and the second antenna 12. Specifically, the first antenna 11 and the second antenna 12 include a current transmission path therebetween; the blocking member 13 is disposed on the current transmission path. More specifically, the first antenna 11 includes a first feeding port 111, the first feeding port 111 being located on a side of the first antenna 11 close to the second antenna 12, for example, a right side of the first antenna 11 in fig. 1; the second antenna 12 comprises a second feeding port 122, the second feeding port 122 being located at a side of the second antenna 12 close to the first antenna 11, e.g. at the left side of the second antenna 12 in fig. 1. In addition, the first antenna 11 and the second antenna 12 may be co-frequency antennas; the first antenna 11 and the second antenna 12 may share the same reference ground port.

Wherein the barrier 13 may comprise one or more metal grid walls; when the barrier 13 includes a plurality of metal grid walls, the plurality of metal grid walls are not connected to each other. Referring to fig. 2 to 4, fig. 2 shows a schematic structural diagram of an antenna including one metal grid wall according to an embodiment of the present disclosure, fig. 3 shows a schematic structural diagram of an antenna including three metal grid walls according to an embodiment of the present disclosure, and fig. 4 shows a front view of an antenna including three metal grid walls according to an embodiment of the present disclosure. As shown in fig. 2, the metal grid wall may be a sheet structure. As shown in fig. 3 and 4, when the barrier 13 includes a plurality of metal grid walls, the plurality of metal grid walls are sheet structures parallel to each other. In the disclosed embodiment the first antenna 11 and the second antenna 12 are located in a first plane, e.g. in a plane parallel to the paper in fig. 4, and the sheet structure is located in a second plane, e.g. in a plane perpendicular to the paper in fig. 4, the first plane being perpendicular to the second plane.

In the embodiment of the present disclosure, the current between the first antenna 11 and the second antenna 12 is transmitted along the surface of the blocking member 13 on the current transmission path. Referring to fig. 5 and 6, fig. 5 shows a schematic diagram of current transmission including one metal grid wall of the embodiment of the present disclosure, and fig. 6 shows a schematic diagram of current transmission including three metal grid walls of the embodiment of the present disclosure. The isolation between adjacent antennas with the same frequency is improved based on the common ground surface current between the antenna ports, and the current between the common ground antenna ports generally selects a path with the minimum impedance and the shortest transmission distance; when the distance between the antennas is close, the isolation between the antennas is seriously deteriorated; according to the embodiment of the invention, the isolation is improved through the metal grid wall, and the propagation distance of the surface current is increased, so that the effect of extending the space distance is achieved. For the terminal antenna design with the increased number of communication antennas and the tight antenna arrangement, the embodiment of the disclosure can effectively improve the isolation between the antennas with the same frequency and improve the communication quality so as to meet the requirement of the terminal on the antenna communication. In the embodiment of the present disclosure, when the barrier 13 includes one metal grid wall, the current transmission path is a first distance, and when the barrier includes a plurality of metal grid walls, the current transmission path is a second distance; the first distance is less than the second distance. The embodiment of the disclosure increases the current transmission path by arranging the barrier, and further increases the path distance by arranging the plurality of sheet metal grid walls.

Referring to fig. 7 to 9, fig. 7 shows a comparative resonance diagram of a first antenna radiation of an embodiment of the present disclosure, fig. 8 shows a comparative resonance diagram of a second antenna radiation of an embodiment of the present disclosure, and fig. 9 shows an isolation contrast diagram of an antenna radiation of an embodiment of the present disclosure. In the embodiment of the disclosure, the frequency band of the antenna of 5150MHz-5850MHz is taken as an example, and it can be seen from the above resonance diagram and the curve representing the isolation S21 that the isolation between the antennas can be improved by adding the metal grid wall; the three metal grid walls are added to generate certain influence on antenna resonance, and the isolation between the antennas is further improved; the isolation degree between the antennas is improved by being related to the path distance of the common-ground current of the actual ports; because the paths of the surface currents between the feed ports are more in the embodiment of the application, the metal grid wall can increase the length of the surface currents on partial paths, the isolation can be improved by about 3dB, and the half of the current between the two ports of the antenna is reduced. To further increase isolation, metal grid walls may also be provided in the entire path of the surface current between the two antenna ports. The present disclosure proposes increasing the isolation between antenna ports by metal grid walls on the path of the common ground metal surface current between two adjacent co-frequency antennas.

Referring to fig. 10, an embodiment of the present disclosure further provides a terminal 800, including: a display module and a metal backplate 100; the display module and the metal back plate 100 are oppositely arranged to form an accommodating space; the terminal 800 further includes a circuit board disposed in the accommodating space, and the antenna 10 in the above embodiment.

The isolation between adjacent antennas with the same frequency can be effectively improved based on the conductor such as the antenna of the terminal of the all-metal back plate. If the distance between adjacent antennas is small, the isolation between the antennas is limited, and when higher communication quality is required, the poor isolation between the antennas can seriously affect the communication quality, which leads to the problems of poor signal connection, reduced transmission data rate or communication interference, and the like. In order to improve the isolation between the antennas with the same frequency, in the embodiment of the disclosure, the grid wall is added between the adjacent antennas, so that the port isolation between the antennas is improved. The terminal antennas share a reference ground, the common-ground signal distance between adjacent antennas is very close, the smaller the common-ground distance between the antenna ports is, the smaller the distributed impedance is, and the worse the isolation degree between the common-ground ports is; because the RF signal electricity has skin effect and the current of the RF signal is on the metal surface, making the metal surface concave-convex is equivalent to increasing the transmission path of the surface current and increasing the distance between the two ports; changing the surface current path of the antenna signal is equivalent to increasing the distance between adjacent antenna ports, thereby improving port isolation between the two antennas.

The design of the present disclosure to improve antenna isolation may be based on slot antennas of all-metal terminal devices, but is not limited to slot antennas. The basic principle of the grid wall is to increase the propagation distance of the surface current of the antenna port, so the barrier member in the embodiment of the disclosure is not limited to the grid wall, and the purpose of increasing the isolation can be achieved by other structures capable of increasing the propagation distance of the surface current; especially if the distance between ports between adjacent co-frequency antennas is small and the isolation is poor. In particular, the present disclosure does not limit the shape, length, and height of the metal grid wall. The grid wall can be arranged in the terminal, and the size can be adjusted according to the actual space; in addition, the number of the metal grid walls and the distance between grids can be adjusted according to the working frequency of the antenna and the distance between ports; if the frequency is higher, the distance between the metal grid walls can be closer; the farther the propagation path of the surface current between the feed ports is, the greater the corresponding isolation degree is; the metal grid wall of the embodiment of the disclosure can be integrated with a metal rear shell.

The embodiment of the present disclosure further provides a terminal 800, which includes: a display module and a back plate; the display module and the back plate are oppositely arranged to form an accommodating space; the antenna further comprises a circuit board arranged in the accommodating space and the antenna 10 in the embodiment. The terminal device of the embodiment of the present disclosure is not limited to a tablet computer, a mobile handheld device, and the like.
