It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, an integrated antenna board provided by an embodiment of the utility model, the integrated antenna board includes:

[0025] substrate1;

[0026] A plurality of first radiators 2 are arranged at intervals on the edge of the substrate 1;

[0027] The central radiator is arranged in the center of the substrate 1, and the first radiators 2 surround the central radiator together; a resistance channel is opened on the central radiator, and the resistance channel divides the central radiator into second radiators 3 with the same number as the first radiators 2, and each second radiator 3 is paired with a first radiator 2; a resistor is set in the resistance channel to isolate two adjacent second radiators 3.

[0028] In this embodiment, the antenna board is a PCBA (Printed Circuit Board Assembly) antenna board, which is usually an antenna board manufactured directly on a PCB by printing technology; the radiator can be a conductor element that directly transmits the radio frequency signal into space, which usually conducts the radio frequency signal to the radiation end of the radiator and then radiates the radio frequency signal from the radiation end;

[0029] In this embodiment, the resistor channel can separate the second radiators 3, and the resistors provided in the resistor channel can further prevent current conduction between the second radiators 3, thereby achieving a better isolation effect on the second radiators 3;

[0030] In the present application, effective isolation is achieved between each group of pairs of first radiators 2 and second radiators 3, so that each group of first radiators 2 and second radiators 3 can work independently without causing excessive interference to radiators of other groups, thereby ensuring communication quality.

[0031] As a preferred embodiment, the substrate 1 is rectangular in shape, and there are four first radiators 2 , which are respectively arranged at four corner edges of the substrate 1 ; each first radiator 2 is L-shaped.

[0032] The central radiator is rectangular, and the resistance channel includes a first channel 4 and a second channel 5. The first channel 4 and the second channel 5 intersect at the center of the central radiator. The first channel 4 is parallel to a set of opposite sides of the central radiator, and the second channel 5 is parallel to another set of opposite sides of the central radiator, so that the formed second radiator 3 is rectangular.

[0033] In this embodiment, a strip resistor can be set in each resistance channel; the central radiator forms four symmetrically arranged radiator groups (each radiator group includes a first radiator 2 and a second radiator 3) through the division of the resistance channel, and each radiator group is located at a corner of the rectangular substrate 1, so that the radiation signal formed by each radiator group is a scattered signal, it is difficult for signals to conflict with each other, and the communication quality can be improved.

[0034] As a preferred embodiment, a resistor limiting portion 6 is provided in the first channel 4 and the second channel 5 to limit the resistor installed in the channel; a circular central resistor is provided at the intersection of the first channel and the second channel.

[0035] In this embodiment, the resistor limiting portion 6 is provided to firmly fix the resistor in the resistor channel to prevent the resistor from being displaced, thereby affecting the isolation effect on the second radiator 3; the central resistor also serves as a limit for the resistor in the channel, and on the other hand, prevents the corner points of the second radiators 3 from contacting and influencing each other.

[0036] As a preferred embodiment, for any first radiator 2, a protrusion is provided on the first radiator 2, and a first series point 21 is provided on the protrusion. A second series point 31 is provided on the second radiator 3 that is paired with the first radiator 2 at a corner point facing the first radiator 2, and two terminals of the same RF cable 7 are respectively connected to the first series point 21 and the second series point 31.

[0037] In this embodiment, the protrusion is arranged to be opposite to the corner point where the second series connection point 31 is located. The protrusion is in the shape of an elongated strip, and its length is determined according to user needs, so that the distance between the first series connection point 21 and the second series connection point 31 is maintained at a set distance to facilitate connection with the RF cable 7.

[0039] A shell body, the shell body is provided with cable through holes having the same number as the first radiator 2;

[0042] In this embodiment, there are four RF cables 7, and the RF signal emitted by the RF transmitter is transmitted to a group of paired radiators through each RF cable 7, and then the signal is radiated to the outside through the radiator; in the antenna board, effective isolation is achieved between each group of paired first radiators 2 and second radiators 3, so that each group of first radiators 2 and second radiators 3 can work independently without causing excessive interference to other groups of radiators, thereby ensuring communication quality.

[0043] As a preferred embodiment, the housing is composed of a first housing 8 and a second housing, and the first housing 8 is detachably connected to the second housing.
