[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The term "connection" in this application includes the meanings of physical structural connection, electrical connection, direct connection or indirect connection, and can be determined specifically according to the required connection situation. In the description of the embodiments of the present invention, the terms "first", "second", etc. are not specific, but are used to distinguish objects with the same name. If there is a description in the specification, the objects with the same name referred to by the terms "first", "second", etc. may be the same objects.

[0027] See also Figure 1 , is a schematic diagram of the structure of the antenna structure 1 in an embodiment of the present application. Figure 1 As shown, the antenna structure 1 includes a first radiation branch 11, a second radiation branch 12, a third radiation branch 13, and a reflection branch 14. The second radiation branch 12 is adjacent to the first radiation branch 11 and is spaced apart, and forms a full-wave dipole antenna T1 with the first radiation branch 11, and the full-wave dipole antenna T1 supports the transmission and reception of electromagnetic wave signals in a preset frequency band. The third radiation branch 13 is a ring with a notch, and the third radiation branch 13 is connected between the first radiation branch 11 and the second radiation branch 12. The reflection branch 14 is located on the side of the third radiation branch 13 away from the first radiation branch 11 and the second radiation branch 12, and is spaced apart and coupled with the third radiation branch 13.

[0028] Among them, the reflecting branch 14 is used to reflect the electromagnetic wave signal of a preset frequency band generated by the full-wave dipole antenna T1 formed by the first radiating branch 11 and the second radiating branch 12 under the coupling action of the third radiating branch 13, so that the beam direction of the electromagnetic wave signal of the preset frequency band is toward the side away from the reflecting branch 14.

[0029] Thus, the antenna structure 1 of the present application forms a full-wave dipole antenna T1 through the second radiating branch 12 and the first radiating branch 11, and can support the transmission and reception of electromagnetic wave signals in a preset frequency band, and couples with the reflecting branch 14 through the third radiating branch 13, so that the reflecting branch 14 can reflect the electromagnetic wave signals in a preset frequency band generated by the full-wave dipole antenna T1 formed by the first radiating branch 11 and the second radiating branch 12, thereby enabling the electromagnetic wave signals originally radiated in all directions by the full-wave dipole antenna T1 to be mainly directed in a predetermined direction away from the reflecting branch 14, thereby achieving a directional radiation effect, and the structure is simple and the overall size is small.

[0030] In some embodiments, the first radiation branch 11, the second radiation branch 12, the third radiation branch 13, and the reflection branch 14 may be substantially located in the same plane, so that they can be suitable for use in certain flat space environments.

[0031] See also Figure 2 , is another schematic diagram of the structure of the antenna structure 1 in some embodiments of the present application. Figure 1 , Figure 2 More component symbols are shown in FIG.

[0032] like Figure 2 As shown, the first radiation branch 11 includes a first end 11a and a second end 11b opposite to each other, and the second radiation branch 12 includes a third end 12a and a fourth end 12b opposite to each other, wherein the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are adjacent to and spaced apart from each other, the third radiation branch 13 is connected to the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12, and the third radiation branch 13 is located on one side of the first radiation branch 11 and the second radiation branch 12, and is located between the first radiation branch 11, the second radiation branch 12 and the reflection branch 14.

[0033] That is, in some embodiments, the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are adjacent to and spaced apart from each other, and the third radiation branch 13 is connected to the first end 11a and the third end 12a of the first radiation branch 11 and the second radiation branch 12, and is connected between the first radiation branch 11 and the second radiation branch 12. The third radiation branch 13 is located on one side of the first radiation branch 11 and the second radiation branch 12 as a whole, and the side of the third radiation branch 13 is away from the first radiation branch 11 and the second radiation branch 12, so that the third radiation branch 13 is approximately located between the first radiation branch 11, the second radiation branch 12 and the reflection branch 14. Thus, the third radiating branch 13 is connected to the first radiating branch 11 and the second radiating branch 12, and is coupled to the reflecting branch 14. Through the coupling effect of the third radiating branch 13, the reflecting branch 14 can reflect the electromagnetic wave signal of a preset frequency band generated by the full-wave dipole antenna T1 formed by the first radiating branch 11 and the second radiating branch 12, thereby enabling the beam direction of the full-wave dipole antenna T1 to be away from the predetermined direction of the reflecting branch 14.

[0034] like Figure 2 As shown, the third radiating branch 13 includes a relative fifth end 13a and a sixth end 13b. In some embodiments, the connection between the third radiating branch 13 and the first end 11a of the first radiating branch 11 and the third end 12a of the second radiating branch 12 may refer to that the fifth end 13a and the sixth end 13b of the third radiating branch 13 are respectively connected to the first end 11a of the first radiating branch 11 and the third end 12a of the second radiating branch 12.

[0035] In some embodiments, the third radiating branch 13 is connected to the first end 11a of the first radiating branch 11 and the third end 12a of the second radiating branch 12, which may also refer to the third radiating branch 13 being connected to the first end 11a of the first radiating branch 11 and the third end 12a of the second radiating branch 12 at positions close to the fifth end 13a and the sixth end 13b, respectively. That is, in some embodiments, the fifth end 13a and the sixth end 13b of the third radiating branch 13 may also extend through the first end 11a of the first radiating branch 11 and the third end 12a of the second radiating branch 12, respectively.

[0036] The third radiating branch 13 in the present application is a ring with a gap, which means that the third radiating branch 13 is an open ring. The third radiating branch 13 can be any open ring structure.

[0037] In some embodiments, the third radiating branch 13 may be an integrally formed structure with the first radiating branch 11 and the second radiating branch 12. In some embodiments, the connection positions of the third radiating branch 13 and the first radiating branch 11 and the second radiating branch 12 may be connected by welding or the like.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the first radiation branch 11 and the second radiation branch 12 extend in the same direction, and the first radiation branch 11 and the second radiation branch 12 are arranged along the same direction. Figure 2 The first direction D1 shown in the figure is arranged at intervals, wherein the first direction D1 is the extension direction of the first radiation branch 11 and the second radiation branch 12; the reflection branch 14 is parallel to the first radiation branch 11 and the second radiation branch 12, and the first radiation branch 11 and the second radiation branch 12 are arranged along the first direction D1. Figure 2 The projection of the second direction D2 on one side of the reflective branch 14 at least partially overlaps with the reflective branch 14 , wherein the second direction D2 is perpendicular to the first direction D1 .

[0039] Among them, in the present application, the extension directions of "A" and "B" are the same, which means that the extension directions of "A" and "B" are approximately the same, that is, it includes the situation that the extension directions of the two may be partially the same and partially different, and may also include the situation that the angle between the extension directions of the two is less than a preset angle, such as 10°, and so on.

[0040] Among them, in this application, "A" and "B" being parallel also means being approximately parallel, that is, it also includes the situation where some structures of the two are parallel and some structures are uneven, and also includes the situation where the angle between the two is less than a preset angle, such as 10°, and so on.

[0041] Among them, in this application, "A" and "B" being perpendicular also means being approximately perpendicular, that is, including the case where the angle between the two is close to 90 degrees, such as 70° to 90°, and so on.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the first radiation branch 11, the second radiation branch 12 and the reflection branch 14 are all straight strips, and the first radiation branch 11 and the second radiation branch 12 are arranged in a "one" shape, and the reflection branch 14 is parallel to the first radiation branch 11 and the second radiation branch 12, and is spaced from each other in the second direction D2, and the first radiation branch 11 and the second radiation branch 12 are arranged along the second direction D2. Figure 2The projection of the second direction D2 shown on one side of the reflection branch 14 at least partially overlaps with the reflection branch 14, that is, the reflection branch 14 is at least partially opposite to the first radiation branch 11 and the second radiation branch 12. In particular, since the electromagnetic wave signal of the preset frequency band generated by the full-wave dipole antenna T1 formed by the first radiation branch 11 and the second radiation branch 12 is mainly generated by the first radiation branch 11 and the second radiation branch 12, the reflection branch 14 is at least partially opposite to the first radiation branch 11 and the second radiation branch 12, and can reflect the electromagnetic waves of the preset frequency band, so that the electromagnetic wave signal originally radiated in all directions can be mainly directed in one direction, thereby achieving a directional radiation effect.

[0043] In some embodiments, the first radiation branch 11, the second radiation branch 12 and the reflection branch 14 may also be arc-shaped with a certain curvature, or bent with a certain curvature, and so on.

[0044] Among them, Figure 1 and Figure 2 As shown, the full-wave dipole antenna T1 formed by the first radiating branch 11, the second radiating branch 12, the third radiating branch 13 and the reflecting branch 14 are arranged in sequence approximately along the second direction D2, and the third radiating branch 13 is located between the full-wave dipole antenna T1 and the reflecting branch 14, and is connected to the full-wave dipole antenna T1, and is spaced apart and coupled with the reflecting branch 14.

[0045] See also Figure 3 , is a schematic diagram of the current distribution of the antenna structure 1 in some embodiments of the present application. Figure 3 As shown, in some embodiments, the first radiating branch 11 and the second radiating branch 12 are electrically connected to the positive terminal p+ and the negative terminal p- of a feed source S1, respectively. The full-wave dipole antenna T1 formed by the first radiating branch 11 and the second radiating branch 12 supports the reception and transmission of electromagnetic wave signals in a preset frequency band under the excitation of the feed source S1. The first radiating branch 11 and the second radiating branch 12 generate a first current i1 in the same direction. The feed source S1 excites the reflecting branch 14 through the third radiating branch 13 to generate a second current i2. The second current i2 is opposite to the direction of the first current i1, thereby forming a reflection effect on the electromagnetic wave signal in the preset frequency band generated by the full-wave dipole antenna T1 and reflecting it.

[0046] That is, in some embodiments, the first radiating branch 11 and the second radiating branch 12 of the antenna structure 1 are respectively connected to the positive terminal p+ and the negative terminal p- of a feed source S1, and support the reception and transmission of electromagnetic wave signals in a preset frequency band under the excitation of the feed source S1, and the first radiating branch 11 and the second radiating branch 12 generate a first current i1 with the same direction. In addition, the feed source S1 and the third radiating branch 13 couple and excite the reflecting branch 14 to generate a second current i2, and the second current i2 is opposite to the direction of the first current i1. Since the reflection branch 14 is at least partially opposite to the first radiation branch 11 and the second radiation branch 12, the current direction is opposite, which is equivalent to being able to offset at least part of the radiation energy of the first radiation branch 11 and the second radiation branch 12 toward the reflection branch 14, so that the radiation energy of the full-wave dipole antenna T1 formed by the first radiation branch 11 and the second radiation branch 12 toward the reflection branch 14 is lower, and since the total radiation energy of the full-wave dipole antenna T1 is constant, when the radiation energy of the full-wave dipole antenna T1 toward the reflection branch 14 is lower, the radiation energy of the full-wave dipole antenna T1 away from the reflection branch 14 will be higher. Since the direction with higher radiation energy is the main radiation direction of the electromagnetic wave signal, that is, the beam direction, it is equivalent to allowing the electromagnetic wave signal of the preset frequency band to be mainly radiated toward the side away from the reflection branch 14, thereby achieving a directional radiation effect.

[0047] Among them, Figure 3 As shown, in some embodiments, the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are respectively connected to the positive terminal p+ and the negative terminal p- of the feed source S1, so that the first radiation branch 11 and the second radiation branch 12 are respectively electrically connected to the positive terminal p+ and the negative terminal p- of the feed source S1. That is, in some embodiments, the first radiation branch 11 and the second radiation branch 12 are respectively electrically connected to the positive terminal p+ and the negative terminal p- of the feed source S1 by connecting the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12, which are close to each other, to the positive terminal p+ and the negative terminal p- of the feed source S1.

[0048] In some embodiments, the positive terminal p+ and the negative terminal p- of the feed source S1 may also be respectively connected to the third radiation branch 13 near the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12, and the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are respectively electrically connected to the positive terminal p+ and the negative terminal p- of the feed source S1 through the third radiation branch 13. This application is not limited here.

[0049] In some embodiments, the distance between the reflective branch 14 and the first radiation branch 11 and the second radiation branch 12 in the second direction is a preset distance. When the distance between the reflective branch 14 and the first radiation branch 11 and the second radiation branch 12 in the second direction is a preset distance, the reflection effect of the reflective branch 14 can be better.

[0050] In some embodiments, the preset distance is a value between 1λ / 2 and 3λ / 2, that is, greater than or equal to 1λ / 2 and less than or equal to three times λ, where λ is the wavelength corresponding to the preset frequency band.

[0051] In some embodiments, Figure 2-Figure 3 As shown, the reflective branch 14 includes a first reflective branch 14a and a second reflective branch 14b, the first reflective branch 14a and the second reflective branch 14b have the same extension direction, and the first reflective branch 14a and the second reflective branch 14b extend along the same direction. Figure 2 The first radiation branches 11 are arranged in a first direction D1 as shown; Figure 2 The projection of the second direction D2 on the side of the reflective branch 14 at least partially overlaps with the first reflective branch 14a, and the projection of the second radiation branch 12 along the second direction on the side of the reflective branch 14 at least partially overlaps with the second reflective branch 14b. Figure 3 As shown, the feed source S1 couples and excites the first reflection branch 14a and the second reflection branch 14b through the third radiation branch 13 to generate a second current i2 in the opposite direction to the first current i1. The first reflection branch 14a and the second reflection branch 14b respectively reflect the electromagnetic wave signals of the preset frequency band generated by the first radiation branch 11 and the second radiation branch 12 to form a reflection effect.

[0052] That is, in some embodiments, the reflection branch 14 includes two reflection branches, namely the first reflection branch 14a and the second reflection branch 14b, and the first reflection branch 14a and the second reflection branch 14b are at least partially opposite to the first radiation branch 11 and the second radiation branch 12, respectively, and the first reflection branch 14a and the second reflection branch 14b both generate a second current i2 in the opposite direction to the first current i1, and can respectively reflect the electromagnetic wave signals generated by the first radiation branch 11 and the second radiation branch 12, thereby achieving a directional radiation effect.

[0053] in, Figure 2 and Figure 3 In the embodiment, the first reflective branch 14a and the second reflective branch 14b are also illustrated by taking a straight bar shape as an example. In some embodiments, the first reflective branch 14a and the second reflective branch 14b may also be an arc shape with a certain curvature, or a bent shape with a certain curvature, etc.

[0054] In some embodiments, the first radiation branch 11 is along Figure 2 The projection of the second direction D2 shown on the side of the reflection branch 14 can be mostly overlapped or completely overlapped with the first reflection branch 14a, and the projection of the second radiation branch 12 on the side of the reflection branch 14 along the second direction can be mostly overlapped or completely overlapped with the second reflection branch 14b, so that the first reflection branch 14a can reflect most of the electromagnetic wave signals generated by the first radiation branch 11, and the second reflection branch 14b can reflect most of the electromagnetic wave signals generated by the second radiation branch 12, which can greatly improve the directional radiation effect. Obviously, in some embodiments, as long as the projection of the first radiation branch 11 on the side of the reflection branch 14 along the second direction D2 partially overlaps with the first reflection branch 14a, and the projection of the second radiation branch 12 on the side of the reflection branch 14 along the second direction partially overlaps with the second reflection branch 14b, the directional radiation effect can be guaranteed to a certain extent, and the communication performance requirements in the predetermined direction can be met.

[0055] See also Figure 4 , is another schematic diagram of the structure of the antenna structure 1 in some embodiments of the present application. In some embodiments, as Figure 4 As shown, the number of the reflective branch nodes 14 may be only one, and the projections of the first radiation branch node 11 and the second radiation branch node 12 on one side of the reflective branch node 14 along the second direction D2 at least partially overlap with the reflective branch node 14, that is, the reflective branch node 14 is at least partially opposite to the first radiation branch node 11 and the second radiation branch node 12.

[0056] Therefore, in some embodiments, the one reflection branch 14 can also be used to reflect the electromagnetic wave signals of a preset frequency band generated by the first radiation branch 11 and the second radiation branch 12, thereby achieving a directional radiation effect.

[0057] See also Figure 5 , is a further structural and current distribution diagram of the antenna structure 1 in some embodiments of the present application. Figure 5 The antenna structure 1 shown is Figure 1-Figure 3 Further elements are added to the structure shown.

[0058] like Figure 5 As shown, the antenna structure 1 also includes a first coupled radiation branch 15 and a second coupled radiation branch 16, and the first coupled radiation branch 15, the first reflection branch 14a, the second reflection branch 14b and the second coupled radiation branch 16 are arranged in sequence along the first direction D1, wherein when the feed source S1 and the third radiation branch 13 couple and excite the first reflection branch 14a and the second reflection branch 14b to generate a second current, the first reflection branch 14a and the second reflection branch 14b further couple and excite the first coupled radiation branch 15 and the second coupled radiation branch 16 to generate a third current i3, and the third current i3 has the same direction as the first current i1, thereby enhancing the radiation energy of the electromagnetic wave signal of the preset frequency band generated by the first radiation branch 11 and the second radiation branch 12.

[0059] That is, in some embodiments, the first coupled radiation branch 15 and the second coupled radiation branch 16 are respectively provided on both sides of the integral structure of the first reflection branch 14a and the second reflection branch 14b, and the first coupled radiation branch 15 and the second coupled radiation branch 16 can respectively generate a third current i3 under further coupling excitation of the first reflection branch 14a and the second reflection branch 14b, and the third current i3 has the same direction as the first current i1 on the first radiation branch 11 and the second radiation branch 12. Since the radiation energy can be increased when the current directions are the same, the radiation energy of the electromagnetic wave signal generated by the full-wave dipole antenna T1 can be effectively increased through the first coupled radiation branch 15 and the second coupled radiation branch 16, thereby improving the gain.

[0060] In some embodiments, Figure 5 As shown, the first coupling radiation branch 15 and the second coupling radiation branch 16 are both in a straight strip shape and extend in the same direction which is substantially the same as the first direction D1.

[0061] In some embodiments, in some embodiments, the first coupling radiation branch 15 and the second coupling radiation branch 16 may also be arc-shaped with a certain curvature, or bent with a certain curvature, and so on.

[0062] In some embodiments, Figure 3-Figure 5 As shown, the third radiation branch 13 includes a coupling branch segment 131 and two connecting branch segments 132, and the two ends of the coupling branch segment 131 are respectively connected to the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 through the two connecting branch segments 132, wherein the coupling branch segment 131 is adjacent to and coupled with the reflection branch 14, and the coupling branch segment 131 generates a fourth current i4 under the excitation of the feed source, and the direction of the fourth current i4 is the same as the direction of the first current i1, so that the coupling branch segment 131 couples and excites the reflection branch 14 to generate the second current i2 with the opposite direction.

[0063] That is, in some embodiments, the third radiation branch 13 includes a coupling branch segment 131 and two connecting branch segments 132, and the two ends of the coupling branch segment 131 are respectively connected to the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 through the two connecting branch segments 132, and the fifth end 13a and the sixth end 13b of the third radiation branch 13 are respectively the ends of the two connecting branch segments 132 away from the coupling branch segment 131. Wherein, when the full-wave dipole antenna T1 supports the transmission and reception of electromagnetic wave signals of a preset frequency band under the excitation of the feed source S1, and the first radiation branch 11 and the second radiation branch 12 generate the first current i1 in the same direction, since the third radiation branch 13 is also connected to the feed source S1, the coupling branch segment 131 can generate a fourth current i4 in the same direction as the first current i1 under the excitation of the feed source S1. The coupling branch segment 131 is adjacent to and coupled with the reflecting branch 14. When one of the two adjacent and coupled branches is excited by the other to generate current, the directions of the two currents are opposite. Therefore, the coupling branch segment 131 couples and excites the reflecting branch 14 to generate the second current i2, and the direction of the second current i2 is opposite to the direction of the fourth current i4 in the coupling branch segment 131, that is, opposite to the direction of the first current i1 generated by the first radiation branch 11 and the second radiation branch 12.

[0064] Furthermore, in some embodiments, the aforementioned feed source S1 couples and excites the reflective branch 14 to generate the second current i2 through the third radiation branch 13, which may mean that the coupled branch segment 131 of the third radiation branch 13 may generate a fourth current i4 with the same direction as the first current i1 under the excitation of the feed source S1, and then the coupled branch segment 131 couples and excites the reflective branch 14 to generate the second current i2 through the fourth current i4.

[0065] Among them, Figure 3 , Figure 5 As shown, when the reflecting branch 14 includes a first reflecting branch 14a and a second reflecting branch 14b, the first reflecting branch 14a and the second reflecting branch 14b are both adjacent to and coupled with the third radiating branch 13, that is, adjacent to and coupled with the coupling branch segment 131 of the third radiating branch 13. Therefore, the first reflecting branch 14a and the second reflecting branch 14b can both generate the second current i2 under the coupling excitation of the coupling branch segment 131.

[0066] Among them, Figure 4 As shown, when there is only one reflecting branch 14, the reflecting branch 14 is adjacent to and coupled with the third radiating branch 13, that is, adjacent to and coupled with the coupling branch segment 131 of the third radiating branch 13. Therefore, the reflecting branch 14 can generate the second current i2 under the coupling excitation of the coupling branch segment 131.

[0067] In the present application, the electrical lengths of the first radiation branch 11 and the second radiation branch 12 are both λ / 2, that is, half λ, where λ is the wavelength corresponding to the preset frequency band. The first radiation branch 11 and the second radiation branch 12 both operate in a half-wavelength resonance mode and support the transmission and reception of electromagnetic wave signals in the preset frequency band.

[0068] In some embodiments, the electrical lengths of the coupling branch segment 131 and the two connecting branch segments 132 are also λ / 2. Therefore, since λ / 2 corresponds to half a wavelength, Figure 3 , Figure 5 As shown in the figure, when the first radiation branch 11 and the second radiation branch 12 both generate the first current i1, for example, the first current i1 is directed to the right direction in the figure, after the first current i1 flows into one of the connecting branch segments 132, for example, the connecting branch segment 132 located on the left side in the figure, the direction will be reversed, and as shown in FIG. Figure 3 , Figure 5As shown in the figure, a current i0 is formed in the connecting branch segment 132 on the left, and after passing through the connecting branch segment 132 of half a wavelength and flowing into the coupling branch segment 131, the direction will change again, so that the current direction of the fourth current i4 in the coupling branch segment 131 will be the same as the first current i1. Among them, after the fourth current i4 in the coupling branch segment 131 flows into another connecting branch segment 132, for example, the connecting branch segment 132 on the right side of the figure, the direction will be reversed, and as shown in FIG. Figure 3 , Figure 5 As shown in the figure, a current i0 is formed in the connecting branch segment 132 on the right, and when it flows into the second radiation branch segment 12 after passing through the half-wavelength connecting branch segment 132, its direction changes again. Therefore, the first current i1 satisfying the second radiation branch segment 12 is still in the same direction as the fourth current i4 in the coupling branch segment 131.

[0069] In some embodiments, the two connecting branch segments 132 extend roughly along the second direction D2, and the currents in the second direction D2 are opposite, canceling each other out in the far field, thereby weakening the radiation energy of the full-wave dipole antenna T1 in a first direction perpendicular to the second direction, and being more conducive to the full-wave dipole antenna T1 being directed toward the side away from the reflective branch 14.

[0070] In some embodiments, the two connecting branch segments 132 are bent segments, straight segments or arc segments. In some embodiments, the coupling branch segment 131 may also be a bent segment, straight segment or arc segment.

[0071] in, Figure 5 In the figure, the coupling branch segment 131 is a straight bar and is parallel to the first radiation branch 11, the second radiation branch 12 and the reflection branch 14. In some embodiments, the coupling branch segment 131 is a straight bar and is parallel to the first radiation branch 11, the second radiation branch 12 and the reflection branch 14, and the coupling branch segment 131 can be better coupled with the reflection branch 14.

[0072] In some embodiments, when the coupling branch segment 131 is a bent segment or an arc segment, the first radiation branch 11, the second radiation branch 12, the first reflection branch 14a and the second reflection branch 14b can also be bent segments or arc segments, and the bending or curvature directions of the coupling branch segment 131, the first radiation branch 11, the second radiation branch 12, the first reflection branch 14a and the second reflection branch 14b are roughly the same, and the bending degree or curvature is also roughly the same, so that the coupling branch segment 131 is a straight strip, and is roughly parallel to the first radiation branch 11, the second radiation branch 12 and the first reflection branch 14a and the second reflection branch 14b in the reflection branch 14.

[0073] Among them, Figure 3-Figure 5 In the figure, the two connecting branch segments 132 are taken as bending segments as an example. Figure 3-Figure 5 As shown, the connecting branch segment 132 connected to the first radiating branch 11 includes a first segment (not numbered in the figure) connected to the first radiating branch 11, a second segment (not numbered in the figure) connected to the coupling branch segment 131, and a third segment (not numbered in the figure) connected between the first segment and the second segment, wherein the first segment and the second segment are approximately perpendicular to the first radiating branch 11, the second segment is approximately parallel to the first radiating branch 11, and the projections of the second segment and the third segment on one side of the first radiating branch 11 partially overlap with the first radiating branch 11.

[0074] Similarly, the connecting branch segment 132 connected to the second radiating branch 12 includes a first segment (not numbered in the figure) connected to the second radiating branch 12, a second segment (not numbered in the figure) connected to the coupling branch segment 131, and a third segment (not numbered in the figure) connected between the first segment and the second segment, wherein the first segment and the second segment in the connecting branch segment 132 connected to the second radiating branch 12 are approximately perpendicular to the second radiating branch 12, the second segment is approximately parallel to the second radiating branch 12, and the projections of the second segment and the third segment on one side of the second radiating branch 12 partially overlap with the first radiating branch 11.

[0075] Thus, if Figure 3-Figure 5 As shown, in some embodiments, the third radiation branch 13 is substantially a "convex" structure with an open top.

[0076] Among them, since the projection of the second segment of the two connecting branch segments 132 on one side of the first radiating branch node 11 and the second radiating branch node 12 partially overlaps with the first radiating branch node 11 and the second radiating branch node 12, it is also possible to block or reflect the electromagnetic wave signal generated by the full-wave dipole antenna T1, and the two connecting branch segments 132 and the reflecting branch node 14 are located on the same side of the first radiating branch node 11 and the second radiating branch node 12, so that the reflecting branch node 14 can further cooperate with the electromagnetic wave signal generated by the full-wave dipole antenna T1 to be directed toward the side away from the reflecting branch node 14.

[0077] See also Figure 6 , is a schematic diagram of a modified example of the antenna structure 1 in some embodiments of the present application. Figure 6 The difference between the antenna structure 1 shown in FIG. 1 and the aforementioned antenna structure 1 is that the two connecting branch segments 132 are straight segments.

[0078] That is, in some embodiments, Figure 6 As shown, the two connecting branch segments 132 are straight segments, and the third radiating branch segment 13 is roughly a triangular structure with an open top. Figure 6 Other structures of the antenna structure 1 shown in FIG. Figure 5 The structure shown is provided as an example.

[0079] See also Figure 7 , is a schematic diagram of another variation example of the antenna structure 1 in some embodiments of the present application. Figure 6 The difference between the antenna structure 1 shown in the figure and the aforementioned antenna structure 1 is that the two connecting branch segments 132 are arc segments.

[0080] That is, in some embodiments, Figure 6 As shown, the two connecting branch segments 132 are arc segments, and the third radiating branch segment 13 is roughly a semicircular structure with an open top. Figure 6 Other structures of the antenna structure 1 shown in FIG. Figure 5 The structure shown is provided as an example.

[0081] See also Figure 8 , is a further structural and current distribution diagram of the antenna structure 1 in some embodiments of the present application.

[0082] in, Figure 8 The antenna structure 1 shown is Figure 5 Further elements are added to the structure shown.

[0083] like Figure 8As shown, the antenna structure 1 also includes a first auxiliary branch 17 and a second auxiliary branch 18. The first auxiliary branch 17 is connected to the second end 11b of the first radiating branch 11 and is set at an angle to the first radiating branch 11. The second auxiliary branch 18 is connected to the fourth end 12b of the second radiating branch 12 and is set at an angle to the second radiating branch 12.

[0084] That is, in some embodiments, the first auxiliary branch 17 and the first radiating branch 11 form a substantially L-shaped structure, and the second auxiliary branch 18 and the second radiating branch 12 also form a substantially L-shaped structure.

[0085] In some embodiments, the angle between the first auxiliary branch 17 and the first radiation branch 11 can be any suitable non-zero angle, for example, an angle between 60° and 120°. In some embodiments, the angle between the second auxiliary branch 18 and the second radiation branch 12 can also be any suitable non-zero angle, for example, an angle between 60° and 120°.

[0086] In some embodiments, by Figure 8 In the structure shown, the first auxiliary branch 17, the second auxiliary branch 18, the first radiation branch 11, the second radiation branch 12 and the third radiation branch 13 roughly form a balun structure, which is beneficial to antenna matching and can effectively improve radiation efficiency.

[0087] In some embodiments, the first auxiliary branch 17, the second auxiliary branch 18, the first radiation branch 11, and the second radiation branch 12 may be an integrally formed structure. In some embodiments, the first auxiliary branch 17 may also be connected to the second end 11b of the first radiation branch 11 by welding or the like, and the second auxiliary branch 18 may also be connected to the fourth end 12b of the second radiation branch 12 by welding or the like.

[0088] Among them, the first auxiliary branch 17 and the second auxiliary branch 18 extend roughly along the second direction D2, and the directions of the currents in the second direction D2 are opposite, and the effects in the far field are offset, thereby further weakening the radiation energy of the full-wave dipole antenna T1 in the first direction perpendicular to the second direction, and being more conducive to the full-wave dipole antenna T1 facing away from the reflective branch 14.

[0089] In some embodiments, the electrical lengths of the first auxiliary branch 17 and the second auxiliary branch 18 are both λ / 2. In some embodiments, since the first auxiliary branch 17 is connected to the first radiation branch 11 and the electrical lengths are both λ / 2, when the first radiation branch 11 generates the first current i1 under the excitation of the feed source S1, the first auxiliary branch 17 will generate a fifth current i5, and the fifth current i5 and the first current i1 of the first radiation branch 11 are opposite to each other on the L-shaped structure formed by the first auxiliary branch 17 and the first radiation branch 11. For example, Figure 8 Similarly, since the second auxiliary branch 18 is connected to the second radiation branch 12 and the electrical lengths are both λ / 2, when the second radiation branch 12 generates the first current i1 under the excitation of the feed source S1, a sixth current i6 will be generated in the second auxiliary branch 18, and the sixth current i6 and the first current i1 of the second radiation branch 12 are opposite to each other on the L-shaped structure formed by the second auxiliary branch 18 and the second radiation branch 12, for example, Figure 8 Therefore, the directions of the currents of the first auxiliary branch 17 and the second auxiliary branch 18 in the second direction D2 are opposite.

[0090] In some embodiments, as described above, the electrical lengths of the first radiation branch 11 and the second radiation branch 12 are both λ / 2, and / or the distance between the reflection branch 14 and the full-wave dipole antenna T1 is λ / 2, etc., wherein λ is the wavelength corresponding to the preset frequency band, so that it can work in a half-wavelength resonant mode. The distance between the reflection branch 14 and the full-wave dipole antenna T1 is λ / 2, which may refer to the preset distance between the reflection branch 14 and the first radiation branch 11 and the second radiation branch 12 in the second direction being λ / 2.

[0091] In some embodiments, as described above, when the reflective branch 14 includes the first reflective branch 14 a and the second reflective branch 14 b , the electrical lengths of the first reflective branch 14 a and the second reflective branch 14 b are also λ / 2.

[0092] In some embodiments, when the reflection branch 14 includes the first reflection branch 14a and the second reflection branch 14b, and the antenna structure 1 also includes the first coupled radiation branch 15 and the second coupled radiation branch 16, the electrical lengths of the first reflection branch 14a, the second reflection branch 14b, the first coupled radiation branch 15 and the second coupled radiation branch 16 are all λ / 2, where λ is the wavelength corresponding to the preset frequency band.

[0093] In some embodiments, as described above, the electrical lengths of the coupling branch segment 131 and the coupling connection branch segment of the third radiation branch 13 are both λ / 2.

[0094] Therefore, by setting the electrical length of the above-mentioned branches or branch segments to λ / 2, it is beneficial to form the above-mentioned currents in various directions, and can achieve resonance in the preset frequency band, reflect electromagnetic waves in the preset frequency band, and enhance radiation energy.

[0095] Among them, Figure 1-Figure 8 As shown in the figures, in some embodiments, except that the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are respectively connected to the fifth end 13a and the sixth end 13b of the third radiation branch 13, the terminals of other branches are open ends.

[0096] In some embodiments, the antenna structure 1 may be made of a conductive material, such as conductive silver paste, copper foil, etc. For example, the antenna structure 1 may be formed by printing conductive silver paste on a substrate.

[0097] In some embodiments, the preset frequency band may be a Wifi 2.4G frequency band or a Bluetooth frequency band, that is, the frequency range of the preset frequency band is approximately 2.4 GHz to 2.5 GHz.

[0098] In some embodiments, the preset frequency band may also be any other frequency band, for example, low frequency, medium and high frequency, Wifi 5G frequency band, N77, N78 and other 5G frequency bands, and so on.

[0099] See also Fig. 9 , which is a schematic diagram of the antenna standing wave ratio obtained through simulation testing when the antenna structure 1 in some embodiments of the present application works in a preset frequency band.

[0100] The antenna structure 1 may be the antenna structure 1 in any of the above embodiments. Fig. 9 Specifically, it can be Figure 8 Taking the antenna structure 1 shown in the figure as an example, a schematic diagram of the antenna standing wave ratio is obtained through simulation testing when it works in a preset frequency band.

[0101] Among them, the lowest antenna standing wave ratio is 1. The closer the antenna standing wave ratio is to 1, the higher the antenna radiation efficiency is.

[0102] in, Fig. 9 The preset frequency band is specifically illustrated by taking the Wifi 2.4G frequency band or the Bluetooth frequency band as an example.

[0103] like Fig. 9As shown, within the frequency range of 2.4 GHz to 2.5 GHz corresponding to the preset frequency band, the antenna standing wave ratio is less than 2, that is, the antenna standing wave ratio is very close to 1. It can be seen that the radiation efficiency of the antenna structure 1 of the present application is relatively high.

[0104] See also Fig.10 as well as Fig.11 , Fig.10 The three-dimensional antenna pattern is obtained through simulation test when the antenna structure 1 in some embodiments of the present application works in a preset frequency band. Fig.11 It is a planar antenna pattern obtained through simulation testing when the antenna structure 1 in some embodiments of the present application works in a preset frequency band.

[0105] The antenna structure 1 may also be the antenna structure 1 in any of the above embodiments. Fig.10 and Fig.11 It can also be specifically Figure 8 The antenna structure 1 shown in the figure is used as an example to obtain the antenna radiation pattern obtained through simulation test when working in a preset frequency band.

[0106] in, Fig.10 In the three-dimensional antenna pattern shown, the darkest part, that is, Fig.10 The reddest part is the main radiation direction of the antenna structure 1 when it works in the preset frequency band, that is, the main lobe direction. Fig.11 In the plane antenna radiation pattern shown, the portion with the longest radial length is the main radiation direction of the antenna structure 1 when working in a preset frequency band, that is, the beam direction.

[0107] from Fig.10 as well as Fig.11 It can be seen that the main radiation direction of the antenna structure 1 when working in the preset frequency band is concentrated in one direction, that is, Fig.10 and Fig.11 The upward direction of the viewing angle shown in is the direction away from the reflective branch 14. Fig.10 as well as Fig.11 It can be seen that the antenna gain of the antenna structure 1 when working in the preset frequency band is about 8.7 dB, the width of the main lobe is about 64°, and the beam is relatively concentrated.

[0108] Therefore, the antenna structure 1 of the present application can achieve better directional radiation, higher gain, and higher radiation performance and radiation efficiency.

[0109] See also Fig.12 , which is a current distribution diagram obtained through simulation testing when the antenna structure 1 in some embodiments of the present application works in a preset frequency band.

[0110] in, Fig.12 for Figure 8 The current distribution diagram obtained through simulation test when the antenna structure 1 shown in FIG. works in a preset frequency band.

[0111] in, Fig.12 The darkest part, that is, the redder part, has more current distributed. Fig.12 It can be seen that more current is distributed on the first radiation branch 11, the second radiation branch 12 and the reflection branch 14. When more current is distributed on the reflection branch 14, a better reflection effect can be achieved, and the directional radiation effect can be effectively improved.

[0112] In some embodiments, all branches in the antenna structure 1 are substantially located in the same plane, and the overall size of the antenna structure 1 is less than 130 mm*44 mm (millimeter). Thus, a flat space environment can be used, and the overall size is small.

[0113] See also Fig.13 , is a structural block diagram of the antenna assembly 2 in some embodiments of the present application. Fig.13 As shown, the antenna assembly 2 may include the antenna structure 1 in any of the aforementioned embodiments, and the antenna assembly 2 may also include a feed source S1 and a feed line L1 connected between the feed source S1 and the antenna structure 1 .

[0114] like Fig.13 As shown, as mentioned above, the feed source S1 includes a positive terminal p+ and a negative terminal p-, and as mentioned above, the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 of the antenna structure 1 are respectively connected to the positive terminal p+ and the negative terminal p- of the feed source S1. The first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are connected to the positive terminal p+ and the negative terminal p- of the feed source S1 through the feed line L1.

[0115] The feed line L1 may be a coaxial cable including two layers of inner and outer conductive wires, wherein the first end 11a of the first radiation branch 11 and the third end 12a of the second radiation branch 12 are respectively connected to the positive terminal p+ and the negative terminal p- of the feed source S1 through the inner and outer layers of conductive wires of the feed line L1.

[0116] See also Fig.14 , which is a schematic diagram of the antenna glass 100 in some embodiments of the present application. Fig.14 As shown, the antenna glass 100 may include the antenna structure 1 in any of the aforementioned embodiments, and the antenna component 2 may further include a glass substrate 101 , wherein the antenna structure 1 is disposed on the glass substrate 101 .

[0117] The glass substrate 101 may be single-layer glass, laminated glass or multi-layer glass, etc. The antenna structure 1 may be disposed on the outer surface of the glass substrate 101 or between two adjacent layers of the glass substrate 101 .

[0118] In some embodiments, the antenna structure 1 may also be disposed on any substrate, where the substrate refers to a device that can provide support. The substrate may be a single-layer or multi-layer structure. The substrate has little effect on the radiation of electromagnetic waves and may be a non-conductive material. For example, the substrate may be a multi-layer structure composed of glass, PVB (Polyvinyl Butyral), etc. The antenna structure 1 may be disposed on the outer surface of the substrate or between two adjacent layers of the substrate.

[0119] In some embodiments, the antenna structure 1 may be a conductive silver paste material or a metal patch (copper foil), and the antenna structure 1 may be formed by printing a conductive silver paste on the glass substrate 101 through a special process. The special process may be a silk screen process or the like.

[0120] Since the materials of glass and conductive silver paste are stable, it can effectively ensure that the antenna structure 1 formed by the conductive silver paste material is stably arranged on the glass substrate 101 , which is beneficial to the structural stability of the antenna glass 100 .

[0121] In addition, in the antenna glass 100 , after the antenna structure 1 is formed on the glass substrate 101 , it is an integrated structure with the glass substrate 101 , so there is no need to install the antenna structure 1 later, thus reducing the subsequent installation process.

[0122] in, Fig.14 In the embodiment, the antenna structure 1 is Figure 1 The antenna structure 1 shown is used as an example for illustration. As mentioned above, the antenna structure 1 included in the antenna glass 100 may be the antenna structure 1 in any of the aforementioned embodiments.

[0123] See also Fig.15 , is a structural block diagram of the device 200 in some embodiments of the present application. Fig.15 As shown, the device 200 may include the aforementioned antenna glass 100 .

[0124] In some embodiments, the device 200 may be a vehicle or other equipment, and the antenna glass 100 may be a vehicle window glass, for example, it may be a vehicle window glass at a door, or it may be a roof glass / windshield / rear windshield at a roof.

[0125] See also Fig.16 , is another structural block diagram of the device 200 in some embodiments of the present application. Fig.16As shown, the device 200 may include the antenna structure 1 in any of the aforementioned embodiments.

[0126] In some embodiments, the device 200 may also be a terminal device such as a mobile phone, a tablet computer, or a laptop computer.

[0127] In some embodiments, the device 200 also includes the aforementioned feed source S1 and feed line L1. For example, when the antenna structure 1 is disposed on the glass substrate 101, the feed source S1 can be disposed at other suitable positions of the device 200. For example, when the device 200 is a vehicle, the feed source S1 can be disposed on a circuit board, and the circuit board can be installed at a position close to the glass substrate 101. The feed source S1 is connected to the antenna structure 1 through the feed line L1.

[0128] When the device 200 is a terminal device such as a mobile phone, a tablet computer, or a laptop computer, the feed source S1 can be set on the main board of the device 200 and connected to the antenna structure 1 through the feed line L1.

[0129] The antenna structure 1, antenna glass 100 and device 200 in the present application form a full-wave dipole antenna T1 through the second radiating branch 12 and the first radiating branch 11, and can support the reception and transmission of electromagnetic wave signals in a preset frequency band, and couple with the reflecting branch 14 through the third radiating branch 13, so that the reflecting branch 14 can reflect the electromagnetic wave signal in a preset frequency band generated by the full-wave dipole antenna T1 formed by the first radiating branch 11 and the second radiating branch 12, thereby enabling the electromagnetic wave signal originally radiated in all directions by the full-wave dipole antenna T1 to be mainly directed in a predetermined direction away from the reflecting branch 14, thereby achieving a directional radiation effect, and the structure is simple and the overall size is small.

[0130] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
