[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, an antenna board provided by an embodiment of the utility model, the antenna board includes:

[0027] substrate1;

[0028] A first radiator 2 is disposed on the substrate 1, and a portion of the first radiator 2 has an arc-shaped profile, thereby forming an arc-shaped radiation end;

[0029] The second radiator 3 is arranged on the substrate 1. The first radiator 2 is provided with an inner groove, which includes a plurality of bends, thereby forming an inner contour radiation end at the bends;

[0030] A first series connection point 22 connected to the first radiator 2;

[0031] The second series connection point 31 is connected to the second radiator 3 . After the radio frequency cable 4 is connected, the first series connection point 22 is connected to the second series connection point 31 , thereby connecting the first radiator 2 to the second radiator 3 .

[0032] In this embodiment, the antenna board is a PCBA (Printed Circuit Board Assembly) antenna board, which is usually an antenna board directly manufactured on a PCB by printing technology;

[0033] In this embodiment, the surfaces of the first radiator 2 and the second radiator 3 are both covered with copper. The second radiator 3 is an antenna relative to the ground. It cooperates with the first radiator to reduce interference and maintain the stability of the radiation signal process.

[0034] In this embodiment, the radiator may be a conductor element that directly transmits the radio frequency signal into space. It usually transmits the radio frequency signal to the radiation end of the radiator, and then transmits the radio frequency signal out through the radiation end at a certain wavelength frequency; the length and shape of the radiation end determine the wavelength frequency and the type of network frequency that can be transmitted (such as 2G, 3G, 4G, 5G, WIFI, Bluetooth);

[0035] In this embodiment, the series connection point is a conductor arranged on the edge of the radiator, and the conductor is welded on the substrate 1, which can play a role in fixing the radiator;

[0036] In the present application, by designing the structures of different lengths and shapes of the first radiator 2 and the second radiator 3, the radiators form radiation ends of several different wavelength frequencies, thereby realizing the propagation of various types of network frequencies and expanding their scope of use.

[0037] As a preferred embodiment, the first radiator 2 includes a protrusion 21, and the first series point 22 is arranged at the end of the protrusion 21; the inner groove of the second radiator 3 includes a main groove and a branch groove connected to the main groove, and the second series point 31 is arranged in the main groove and connected to the main groove wall; the protrusion 21 is in the main groove, so that the distance between the first series point 22 and the second series point 31 is less than the set distance.

[0038] In this embodiment, the set distance can be 2 cm or other lengths. The user can determine the set distance specifically based on the length of the RF cable 4, which is not limited here. The distance between the first series point 22 and the second series point 31 is controlled within the set distance, which can facilitate the user to connect the first series point 22 and the second series point 31 through the RF cable. In the present application, the mosaic design between the protrusion 21 and the main groove makes full use of the position space on the substrate 1, and can install a larger area of ​​radiator on the limited space of the substrate 1, thereby improving the signal radiation effect.

[0039] As a preferred embodiment, the main groove is bent and bifurcated to form two branch grooves, and the widths of the two branch grooves are different; each branch groove extends for a set length, further bends, and forms a strip-shaped inner contour radiating end at the bend.

[0040] The substrate 1 is in the shape of a long strip, and the edge of one end of the substrate 1 is designed to be arc-shaped. The portion of the first radiator 2 located at the end is designed according to the shape of the end to form an arc-shaped radiation end.

[0041] In this embodiment, the set length can be 3cm, 5cm or other lengths, depending on the length of the radiator, and is not limited here; each branch groove can have one bend or multiple bends, and the long strip radiators between the grooves formed after each bend (the lengths of each long strip radiator are different), that is, the inner contour radiating end, and each inner contour radiating end can produce different wavelength frequencies; for the first radiator 2, the arc-shaped radiating end formed at the end of the substrate 1 is a 'convex' arc-shaped radiating end. In addition to this radiating end, the first radiator 2 also includes a concave arc-shaped design, thereby forming a 'concave' arc-shaped radiating end.

[0042] like Figure 2 As shown, an embodiment of the utility model further provides an antenna, the antenna comprising:

[0043] Base 5;

[0044] The antenna plate is arranged on the base 5;

[0045] The antenna housing 7 is arranged in cooperation with the antenna board and is used to protect the antenna board;

[0046] A radio frequency cable 4, one end of the radio frequency cable 4 is connected to the antenna board, and the other end is connected to the radio frequency connector;

[0047] The RF connector 6 has one end connected to the RF cable 4 and the other end used for docking and installation with the IoT product.

[0048] In this embodiment, the antenna board is a flat-plate structure, and the antenna housing 7 is a cylindrical structure. The antenna board can be installed in the internal space of the antenna housing 7. A limiting mechanism is provided inside the antenna housing 7. After the antenna board is installed in the antenna housing 7, the limiting mechanism limits it to prevent the antenna board from shaking in the antenna housing 7; one end of the RF connector 6 arranged in the base 5 can be connected to the external Internet of Things product by radio frequency. The Internet of Things product transmits a radio frequency signal, and the signal is transmitted to the radiator through the RF connector 6 and the RF cable 4, so that the radiator transmits the signal to the external space. Due to the different structural designs in the first radiator 2 and the second radiator 3, the radiator forms a number of radiation ends of different lengths and shapes, which can generate different wavelength frequencies to achieve the propagation of multiple network frequencies, thereby expanding its scope of use.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
