[0070] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0071] Refer to Figures 1 to 5 As shown, for the convenience of introduction, the upper, lower, left, and right directions are adopted in the corresponding drawings to facilitate the introduction of the relative positional relationship between various parts of the present application, and it should not be construed as a limitation on the absolute position.

[0072] Moreover, in the present application, the first direction corresponds to the left - right direction, and the second direction corresponds to the up - down direction; similarly, here the first direction indicating the front - back direction is only for the convenience of introducing the specific embodiments of the present application, and there is no absolute corresponding relationship between the first direction and the left - right direction. Similarly, there is no absolute corresponding relationship between the second direction and the up - down direction.

[0073] The first direction and the second direction of the present application are also only for expressing the relative positional relationship, and they only indicate the general orientation, rather than the absolute geometric relationship.

[0074] According to the first aspect of the present application, refer to Figures 1 to 5 , the present application provides an antenna 100, including a substrate 110, a first - type radiation unit 120, and a second - type radiation unit 130.

[0075] Among them, the substrate 110 is formed with a via 11a1, the first - type radiation unit 120 and the second - type radiation unit 130 are located on different surfaces of the substrate 110, and the first - type radiation unit 120 and the second - type radiation unit 130 are connected to the substrate 110 through the via 11a1.

[0076] Through the above technical solution, two types of radiation units are arranged on both side surfaces of the substrate 110, reducing the mutual coupling between the first type of radiation unit 120 and the second type of radiation unit 130, effectively reducing the non-circularity of the radiation pattern of the antenna 100, and further enabling the antenna 100 to have better omnidirectional radiation characteristics and improving the isolation between the first type of radiation unit 120 and the second type of radiation unit.

[0077] Since two different types of radiation units are arranged on both side surfaces of the substrate 110, the antenna 100 has the advantages of dual-band, high gain, and omnidirectional radiation, and minimizes the mutual influence and coupling between the antennas 100.

[0078] In the present application, the frequency band of the first type of radiation unit 120 is 5.725 GHz - 5.85 GHz, and the frequency band of the second type of radiation unit 130 is 2.4 GHz - 2.484 GHz. The dual-band antenna 100 has high gain and good omnidirectional radiation characteristics.

[0079] In some embodiments, the via hole has a connecting body.

[0080] The first type of radiation unit 120 includes: a first radiation portion 121 and a second radiation portion 122.

[0081] Wherein, both the first radiation portion 121 and the second radiation portion 122 are formed on the same surface of the substrate 110, and the first radiation portion 121 and the second radiation portion 122 are connected by the connecting body in the via hole.

[0082] By arranging the connecting body in the via hole, the first radiation portion 121 and the second radiation portion 122 of the first type of radiation unit 120 can be arranged on the same surface of the substrate 110, leaving a layout position for the second type of radiation unit 130. As a result, the first type of radiation unit 120 and the second type of radiation unit 130 can be arranged on both side surfaces of the substrate 110 respectively, enabling signal transmission or reception using dual bands. Moreover, this setting method is simple and can form radiation units with different frequency bands on a single substrate 110 without adding additional structures, effectively reducing the volume of the antenna 100.

[0083] In some embodiments, the connecting body can be configured as a metal layer on the inner wall surface of the via hole, defined as a metal via hole. The connection between the radiation portions of the first type of radiation unit 120 is realized using the metal via hole, and the implementation method is simple. Moreover, the effect that the radiation portions of the first type of radiation unit 120 are located on the same surface can be achieved using the metal via holes on the substrate 110 without using other components for connection.

[0085] Wherein, the first direction is arranged parallel to the center line 11b, and the second direction is arranged perpendicular or inclined to the center line 11b.

[0086] In this application, the first direction and the second direction are configured to be perpendicular.

[0087] By arranging the radiation parts of the first radiation unit in sequence along the first direction and forming an overall symmetric arrangement along the second direction, the first radiation part and the second radiation part included in the first type of radiation unit 120 are symmetrically arranged, so that one or more first type of radiation units 120 have the characteristic of high gain.

[0088] In some embodiments, the vertical distances of the two radiation parts of the first type of radiation unit 120 from the center line 11b along the second direction are set to be the same.

[0089] By setting the vertical distances of the two radiation parts of at least one first type of radiation unit 120 from the center line 11b along the second direction to be the same, a symmetric dipole can be formed, further improving the gain of the antenna 100.

[0090] Reference Figure 5 , the vertical distance of the first radiation part 121 from the center line 11b along the second direction is set to be the same as d1, and the vertical distance of the second radiation part 122 from the center line 11b along the second direction is set to be the same as d2, then d1 is equal to d2.

[0091] In some embodiments, the different first type of radiation units 120 located on both sides of the center line of the substrate 110 can also be configured to be mirror symmetric with respect to the center line.

[0092] In some embodiments, the vertical distances of at least two first type of radiation units 120 from the center line 11b along the second direction are set to be the same.

[0093] By setting the vertical distances of at least two first type of radiation units 120 from the center line 11b along the second direction to be the same, a linear array antenna 100 is formed among all the first type of radiation units 120, further improving the gain of the antenna 100, so that the antenna 100 of this application has the characteristic of high gain.
