接地结构132分别到馈电结构12的连接线之间的夹角A1,A2相等,A1=A2=180°,即,第一接地结构131及第二接地结构132以馈电结构12为对称轴或对称中心,轴对称或中心对称地分布在辐射片11上。Optionally, as shown in FIG. 1 , the first ground structure 131 and the second ground structure 132 are respectively located on two sides of the feed structure 12 , and are in line with the feed structure 12 , and the first ground structure 131 and the second The distance a1, a2 of the ground structure 132 to the feed structure 12 is equal, the first ground structure 131, the second

明实施例对天线部件1的高度不做特别限定,例如,可以设置第一接地结构131及第二接地结构132为10mm,由于馈电结构12不能直接接地,因此可以设置为比接地结构短0.5mm至1mm之间,例如可以设置为9.5mm。Optionally, the height of the antenna component 1 of the first ground structure 131 or the second ground structure 132 may be determined according to a bandwidth and an operating frequency band of an antenna configuring the antenna component 1. Optionally, the first ground structure 131 or the second ground structure The height of the 132 antenna component 1 is proportional to the bandwidth of the antenna. The height of the antenna component 1 is greater than the height of the ground structure, which is the sum of the height of the ground structure and the thickness of the radiation piece. Since the radiation piece 11 is a metal foil, the height of the antenna component 1 can be the first ground structure 131 and the second ground. The height of the structure 132 is determined, that is, the height of the antenna component is consistent with the height of the ground structure. Therefore, the height of the ground structure can be determined according to the antenna bandwidth and the operating frequency band. This hair
The height of the antenna component 1 is not particularly limited. For example, the first ground structure 131 and the second ground structure 132 may be set to 10 mm. Since the feed structure 12 cannot be directly grounded, it may be set to be shorter than the ground structure by 0.5. Between mm and 1 mm, for example, it can be set to 9.5 mm.
可以理解,第一接地结构131及第二接地结构132可以是等高的。It can be understood that the first ground structure 131 and the second ground structure 132 can be of equal height.
可以理解,第一接地结构131及第二接地结构132可以是相同形状的金属结构,例如都是金属圆柱体或者矩形金属薄片;也可以是不同形状的金属结构,例如一个是金属圆柱体,另一个是矩形金属薄片,即只要两个接地结构的高度基本保持一致且以馈电结构为准对称分布即可,本发明实施例对此不做特别限定。可以理解,第一接地结构131或第二接地结构132也可以是接近圆柱形或矩形的形状,略有不规则的形状设置不会对本发明实施例提供的天线部件1的性能产生影响。It can be understood that the first ground structure 131 and the second ground structure 132 may be metal structures of the same shape, for example, all metal cylinders or rectangular metal foils; or metal structures of different shapes, for example, one is a metal cylinder, and the other is a metal cylinder. One embodiment is a rectangular metal foil, that is, the height of the two grounding structures is substantially the same, and the distribution is symmetrically distributed. It can be understood that the first ground structure 131 or the second ground structure 132 may also be a shape close to a cylinder or a rectangle, and a slightly irregular shape setting does not affect the performance of the antenna component 1 provided by the embodiment of the present invention.
可选地,作为本发明的另一个实施例,天线部件1可以包括三个以上的接地结构。如图2所示,以馈电结构12为中心,在辐射片11上对称设置第一接地结构131’、第二接地结构132’及第三接地结构133’。Alternatively, as another embodiment of the present invention, the antenna component 1 may include more than three ground structures. As shown in Fig. 2, a first ground structure 131', a second ground structure 132', and a third ground structure 133' are symmetrically disposed on the radiation sheet 11 centering on the feed structure 12.
如图2所示,第一接地结构131’、第二接地结构132’及第三接地结构133’均匀分布在边缘区域15内,馈电结构12位于中心区域14内。第一接地结构131’、第二接地结构132’及第三接地结构133’到馈电结构12的距离分别为b1,b2,b3,且满足b1=b2=b3,第一接地结构131’、第二接地结构132’及第三接地结构133’到馈电结构12的连接线之间的夹角分别为B1,B2,B3,且满足B1=B2=B3=120°。即,三个接地结构之间的连接线可以构成一个等边三角形。As shown in FIG. 2, the first ground structure 131', the second ground structure 132', and the third ground structure 133' are evenly distributed within the edge region 15, and the feed structure 12 is located within the central region 14. The distances from the first ground structure 131', the second ground structure 132', and the third ground structure 133' to the feed structure 12 are b1, b2, b3, respectively, and satisfy b1 = b2 = b3, the first ground structure 131', The angle between the second grounding structure 132' and the third grounding structure 133' to the connecting line of the feeding structure 12 is B1, B2, B3, respectively, and B1 = B2 = B3 = 120° is satisfied. That is, the connecting lines between the three ground structures may constitute an equilateral triangle.
可选地,在本发明其他的实施例中,第一接地结构131’、第二接地结构132’及第三接地结构133’的连接线也可以构成一个近似的等边三角形,即允许b1≈b2≈b3,B1≈B2≈B3,具体可以参照图1所示实施例部分的相关说明,在此不做赘述。
Optionally, in other embodiments of the present invention, the connection lines of the first ground structure 131', the second ground structure 132', and the third ground structure 133' may also form an approximate equilateral triangle, that is, allow b1≈ B2≈b3, B1≈B2≈B3, for details, refer to the related description of the embodiment shown in FIG. 1, and no further details are provided herein.
在该实施例中,馈电结构12的投影点可以位于该等边三角形的中心点或中心点附近。In this embodiment, the projection point of the feed structure 12 can be located near the center point or center point of the equilateral triangle.
类似地,如图3所示,当天线部件1中包含四个接地结构16时,该四个接地结构16的连接线构成一个正方形;可选地,该四个接地结构16的连接线也可以构成一个近似的正方形。馈电结构12的投影点位于该正方形的中心点或中心点附近。具体可以参照本发明其他实施例中的相关说明,在此不做赘述。Similarly, as shown in FIG. 3, when the antenna component 1 includes four ground structures 16, the connection lines of the four ground structures 16 form a square; alternatively, the connection lines of the four ground structures 16 may also Form an approximate square. The projection point of the feed structure 12 is located near the center point or center point of the square. For details, refer to the related description in other embodiments of the present invention, and no further details are provided herein.
在本发明实施例中,辐射片11的面积与天线工作频段相关。具体地,辐射片11的面积与信号的波长成正比,同时波长与频率成反比,因此,天线工作频段越高,辐射片11的面积可以越小。例如,当使用该天线部件11的天线工作在1.7G~2.1G的频段时,辐射片11的直径可以在[30mm,40mm]之间选取;当天线工作在2.3G~2.6G的频段时,辐射片11的直径可以在[20mm,30mm]之间选取,本领域技术人员可以根据天线性能的实际需求设置合适面积的辐射片,本发明实施例对此不做任何限制。In the embodiment of the present invention, the area of the radiation sheet 11 is related to the antenna operating frequency band. Specifically, the area of the radiation sheet 11 is proportional to the wavelength of the signal, and the wavelength is inversely proportional to the frequency. Therefore, the higher the antenna operating frequency band, the smaller the area of the radiation sheet 11 can be. For example, when the antenna using the antenna component 11 operates in a frequency band of 1.7 G to 2.1 G, the diameter of the radiation piece 11 can be selected between [30 mm, 40 mm]; when the antenna operates in a frequency band of 2.3 G to 2.6 G, The diameter of the radiation sheet 11 can be selected between [20 mm, 30 mm], and a person skilled in the art can set a suitable area of the radiation sheet according to the actual requirements of the antenna performance, which is not limited in the embodiment of the present invention.
需要指出的是,接地结构的个数与配置该天线部件的天线的工作频段相关。可选地,当接地结构越多时,配置该天线部件的天线的工作频段将越偏向高频部分,即接地结构数量与天线的工作频段成正比例关系。结合辐射片面积与天线工作频段的反比例关系,在接地结构数量较多的情况下,为了保证天线能在特定的较低频段内正常工作,需要增加辐射片的面积。因此,接地结构的数量可以根据天线部件的实际性能需求确定,考虑到天线的小型化要求,可以将接地结构的数量配置为2根,3根或4根。It should be noted that the number of ground structures is related to the operating frequency band of the antenna in which the antenna component is disposed. Optionally, when the number of ground structures is larger, the working frequency band of the antenna configuring the antenna component will be biased toward the high frequency portion, that is, the number of ground structures is proportional to the operating frequency band of the antenna. In combination with the inverse proportional relationship between the area of the radiation patch and the operating frequency band of the antenna, in the case of a large number of grounding structures, in order to ensure that the antenna can work normally in a specific lower frequency band, it is necessary to increase the area of the radiation sheet.
