For the convenience of description, the electronic device 100 is in the first viewing angle as a reference for definition, the width direction of the electronic device 100 is defined as the X-axis direction, and the length direction of the electronic device 100 is defined as the Y-axis direction The thickness direction of the electronic device 100 is defined as the Z-axis direction.

请参照图2，本申请提供了一种透镜天线阵列10。所述透镜天线阵列10包括依次排列的多个天线透镜1及多个辐射体2。请参照图3及图4，所述天线透镜1包括依次层叠设置的第一金属板11、介质透镜12及第二金属板13。所述介质透镜12具有设于所述第一金属板11与所述第二金属板13之间的弧形面121及与所述弧形面121相背设置的矩形面122。每个所述辐射体2设于一个所述介质透镜12的矩形面122。至少一个所述辐射体2相对所述介质透镜12的焦点位置120偏移。当所述辐射体2辐射的电磁波信号经所述天线透镜1传导后从所述弧形面121射出时，所述电磁波信号的波束指向随着所述至少一个辐射体2相对所述介质透镜12的焦点位置120偏移而改变。请参照图3，具体的，介质透镜12的焦点位置120为介质透镜12的半圆部125的焦点。换而言之，以辐射体2位于介质透镜12的焦点位置120时，所述辐射体2辐射的电磁波信号的波束指向为基准方向。基准方向平行于天线透镜1的中轴线。当辐射体2相对所述介质透镜12的焦点位置120偏移，所述辐射体2辐射的电磁波信号的波束指向偏离所述基准方向。辐射体2相对所述介质透镜12的焦点位置120偏移的距离越大，电磁波信号的波束指向偏离于所述基准方向的幅度越大。可以理解的，所述电磁波信号可以为毫米波信号，以使毫米波天线在电子设备中得到较好的应用，提高电子设备的通讯能力。Referring to FIG. 2 , the present application provides a lens antenna array 10 . The lens antenna array 10 includes a plurality of antenna lenses 1 and a plurality of radiators 2 arranged in sequence. Referring to FIG. 3 and FIG. 4 , the antenna lens 1 includes a first metal plate 11 , a dielectric lens 12 and a second metal plate 13 that are stacked in sequence. The dielectric lens 12 has an arc-shaped surface 121 disposed between the first metal plate 11 and the second metal plate 13 and a rectangular surface 122 disposed opposite to the arc-shaped surface 121 . Each of the radiators 2 is disposed on a rectangular surface 122 of the dielectric lens 12 . At least one of the radiators 2 is offset relative to the focal position 120 of the dielectric lens 12 . When the electromagnetic wave signal radiated by the radiator 2 is conducted through the antenna lens 1 and then emitted from the arc-shaped surface 121 , the beam direction of the electromagnetic wave signal follows the direction of the at least one radiator 2 relative to the dielectric lens 12 . The focal position of 120 is shifted and changed. Referring to FIG. 3 , specifically, the focal position 120 of the dielectric lens 12 is the focal point of the semicircular portion 125 of the dielectric lens 12 . In other words, when the radiator 2 is located at the focal position 120 of the dielectric lens 12, the beam direction of the electromagnetic wave signal radiated by the radiator 2 is taken as the reference direction. The reference direction is parallel to the central axis of the antenna lens 1 . When the radiator 2 is offset relative to the focal position 120 of the dielectric lens 12 , the beam of the electromagnetic wave signal radiated by the radiator 2 is directed away from the reference direction. The greater the offset distance of the radiator 2 relative to the focal position 120 of the dielectric lens 12, the greater the deviation of the beam direction of the electromagnetic wave signal from the reference direction. It can be understood that the electromagnetic wave signal can be a millimeter wave signal, so that the millimeter wave antenna can be better applied in the electronic device, and the communication capability of the electronic device can be improved.

通过设置透镜天线阵列10中辐射体2相对所述介质透镜12的焦点位置120偏移，以使辐射体2产生的电磁波信号经所述天线透镜1传导后的波束指向偏离天线透镜1的中轴线，故而电磁波信号的波束指向可以根据辐射体2相对所述介质透镜12的焦点的位置调节，进而形成波束指向可调节的透镜天线阵列10，以实现波束扫描。By setting the focal position 120 of the radiator 2 in the lens antenna array 10 to be offset relative to the dielectric lens 12 , the beam of the electromagnetic wave signal generated by the radiator 2 after being conducted by the antenna lens 1 is directed away from the central axis of the antenna lens 1 . Therefore, the beam direction of the electromagnetic wave signal can be adjusted according to the position of the radiator 2 relative to the focal point of the dielectric lens 12, thereby forming the lens antenna array 10 with adjustable beam direction to realize beam scanning.

具体的，请参照图2，透镜天线阵列10包括多个透镜天线单元14。多个透镜天线单元14呈直线阵列或二维阵列或三维阵列排布。本实施例中，以多个透镜天线单元14呈直线阵列排布为例进行说明。透镜天线单元14包括一个天线透镜1及一个辐射体2。天线透镜1包括依次层叠设置的第一金属板11、介质透镜12及第二金属板13。其中，介质透镜12的基材为损耗小，介电常数适当，且不会对电磁波的电场产生干扰的材质，例如陶瓷材料、高分子材料等。高分子材料可选用具有优良的化学稳定性、耐腐蚀性，使用寿命长的材料，例如，聚四氟乙烯、环氧树脂等。Specifically, referring to FIG. 2 , the lens antenna array 10 includes a plurality of lens antenna units 14 .

The first metal plate 11 and the second metal plate 13 are made of materials with good electrical conductivity, including but not limited to gold, silver, copper, and the like. The first metal plate 11 and the second metal plate 13 also function to protect the dielectric lens 12 . In other embodiments, the first metal plate 11 and the second metal plate 13 may be replaced by metal thin films to reduce the thickness and weight of the lens antenna unit 14 .

The rectangular surface 122 of the antenna lens 1 can be In order to integrate with the plane circuit, the radiator 2 can be set on the antenna lens 1 easily.

举例而言，所述弧形面121为半圆部125的弧形侧面。该弧形面121连接第一表面123与第二表面124。所述弧形面121为半圆柱面。所述矩形面122设于所述矩形部126。For example, the arc-shaped surface 121 is an arc-shaped side surface of the semicircular portion 125 . The arc-shaped surface 121 connects the first surface 123 and the second surface 124 . The arc-shaped surface 121 is a semi-cylindrical surface. The rectangular surface 122 is provided on the rectangular portion 126 .

本申请对于天线透镜1的半圆部125和矩形部126的尺寸不做限定，只需满足当辐射体2设于介质透镜12的焦点位置120时，辐射体2辐射的电磁波信号能够高效地经天线透镜1射出，且尽量减小天线透镜1的尺寸，以减少在电子设备100中占据的空间，利于电子设备100的小型化。此外，通过调整天线透镜1的半圆部125的直径和天线透镜1的焦距，可以方便地设计不同增益和尺寸的透镜天线单元14，从而可以尽可能的减小透镜天线阵列10的尺寸，减小在电子设备100内占据的空间，利于电子设备100的小型化。The size of the semicircular portion 125 and the rectangular portion 126 of the antenna lens 1 is not limited in this application, as long as the radiator 2 is set at the focal position 120 of the dielectric lens 12, the electromagnetic wave signal radiated by the radiator 2 can efficiently pass through the antenna. The lens 1 is emitted, and the size of the antenna lens 1 is reduced as much as possible, so as to reduce the space occupied in the electronic device 100 and facilitate the miniaturization of the electronic device 100 . In addition, by adjusting the diameter of the semicircular portion 125 of the antenna lens 1 and the focal length of the antenna lens 1, the lens antenna units 14 with different gains and sizes can be conveniently designed, so that the size of the lens antenna array 10 can be reduced as much as possible, reducing the The space occupied in the electronic device 100 is beneficial to the miniaturization of the electronic device 100 .

举例而言，矩形部126沿X轴方向的长度可以为半圆部125的焦距。再举例而言，矩形部126沿X轴方向的长度可以小于半圆部125的焦距。For example, the length of the rectangular portion 126 along the X-axis direction may be the focal length of the semicircular portion 125 . For another example, the length of the rectangular portion 126 along the X-axis direction may be smaller than the focal length of the semicircular portion 125 .

可以理解的，天线透镜1的半圆部125可以替换为半椭圆柱，可设计出半椭圆柱透镜天线，调整半椭圆柱的短轴和长轴可优化透镜天线的增益和焦距，设计自由度更大，便于应用与不同手机型号。It can be understood that the semi-circular part 125 of the antenna lens 1 can be replaced with a semi-elliptical cylinder, and a semi-elliptical cylinder lens antenna can be designed. Adjusting the short axis and the long axis of the semi-elliptical cylinder can optimize the gain and focal length of the lens antenna, and the design freedom is more. Large for easy application with different mobile phone models.

当辐射体2位于矩形面122时，辐射体2辐射的电磁波信号经矩形面122进入天线透镜1内，在天线透镜1中传导之后再经弧形面121射出。在电磁波信号射出的过程中，电磁波信号会在弧形面121上发生折射，以改变电磁波信号传播方向。根据折射定律，由于天线透镜1的折射率大于空气的折射率不同，所以电磁波信号的折射角小于入射角，从而电磁波信号在从弧形面121射出之后的辐射范围减小，形成指向性更为明确的波束。换而言之，天线透镜1在X－Y面上对电磁波信号起到汇聚作用，故而将电磁波信号的能量集中形成指向明确的波束，以提高电磁波信号的增益。When the radiator 2 is located on the rectangular surface 122 , the electromagnetic wave signal radiated by the radiator 2 enters the antenna lens 1 through the rectangular surface 122 , is conducted in the antenna lens 1 and then exits through the arcuate surface 121 . In the process of emitting the electromagnetic wave signal, the electromagnetic wave signal will be refracted on the arc surface 121 to change the propagation direction of the electromagnetic wave signal. According to the law of refraction, since the refractive index of the antenna lens 1 is greater than the refractive index of the air, the refraction angle of the electromagnetic wave signal is smaller than the incident angle, so the radiation range of the electromagnetic wave signal after being emitted from the arc surface 121 is reduced, resulting in a more directivity. clear beam. In other words, the antenna lens 1 has a converging effect on the electromagnetic wave signal on the XY plane, so that the energy of the electromagnetic wave signal is concentrated to form a beam with a clear direction, so as to improve the gain of the electromagnetic wave signal.

需要说明的是，在辐射体2接受电磁波信号的过程中，空间中的电磁波信号可以通过弧形面121汇聚到辐射体2上，由于弧形面121的面积相对辐射体2的面积较大，所以天线透镜1能够在空间中接受更多的电磁波信号，并将这些电磁波信号汇聚到辐射体2，本申请可以增加辐射体2接受电磁波的能量，提高电子设备100的通讯质量。It should be noted that in the process of receiving the electromagnetic wave signal by the radiator 2, the electromagnetic wave signal in the space can be concentrated on the radiator 2 through the arc surface 121. Since the area of the arc surface 121 is larger than that of the radiator 2, Therefore, the antenna lens 1 can receive more electromagnetic wave signals in space, and gather these electromagnetic wave signals to the radiator 2 . The present application can increase the energy of the electromagnetic wave received by the radiator 2 and improve the communication quality of the electronic device 100 .

举例而言，请参阅图3及图4，当辐射体2位于介质透镜12的焦点位置120时，辐射体2所辐射的电磁波信号在弧形面121上发生折射后的传播方向变成平行于X轴方向的平面波束并从弧形面121辐射出去，以增加辐射体2所辐射的电磁波信号的指向性，及提高辐射体2所辐射的电磁波信号的增益。这种透镜天线单元14的方向图在X－Y面上为窄波束(见图3中椭圆形的虚线部分)，在X－Z面上为宽波束(见图4中椭圆形的虚线部分)。窄波束是指波束的覆盖范围较窄，宽波束是指波束的覆盖范围较宽。For example, referring to FIG. 3 and FIG. 4 , when the radiator 2 is located at the focal position 120 of the dielectric lens 12 , the propagation direction of the electromagnetic wave signal radiated by the radiator 2 after being refracted on the curved surface 121 becomes parallel to The plane beam in the X-axis direction is radiated from the arc surface 121 to increase the directivity of the electromagnetic wave signal radiated by the radiator 2 and improve the gain of the electromagnetic wave signal radiated by the radiator 2 . The directional pattern of this lens antenna unit 14 is a narrow beam on the XY plane (see the ellipse dashed line part in Figure 3), and a wide beam on the X-Z plane (see the ellipse dashed line part in Figure 4) . Narrow beam means that the coverage area of the beam is narrow, and wide beam means that the coverage area of the beam is wider.

举例而言，请参阅图5，当辐射体2偏离于介质透镜12的焦点位置120时，辐射体2所辐射的电磁波信号在弧形面121上发生折射后形成与X轴方向具有夹角的波束。辐射体2偏离介质透镜12的焦点位置120的距离越大，辐射体2所辐射的波束指向与X轴方向形成的夹角越大。定义介质透镜12的中轴线127平行于X轴方向，且介质透镜12关于中轴线127对称。介质透镜12的焦点位置120位于中轴线127上，当辐射体2位于中轴线127的一侧时，辐射体2所辐射的波束指向中轴线127的另一侧。For example, referring to FIG. 5 , when the radiator 2 deviates from the focal position 120 of the dielectric lens 12 , the electromagnetic wave signal radiated by the radiator 2 is refracted on the arc-shaped surface 121 to form an included angle with the X-axis direction. beam. The greater the distance that the radiator 2 deviates from the focal position 120 of the dielectric lens 12, the greater the included angle formed between the direction of the beam radiated by the radiator 2 and the X-axis direction. The central axis 127 defining the dielectric lens 12 is parallel to the X-axis direction, and the dielectric lens 12 is symmetrical about the central axis 127 . The focal position 120 of the dielectric lens 12 is located on the central axis 127 . When the radiator 2 is located on one side of the central axis 127 , the beam radiated by the radiator 2 is directed to the other side of the central axis 127 .

需要说明的是，上述说明了辐射体2辐射电磁波波束的指向会随着辐射体2偏离于介质透镜12的焦点位置120的变化而变化，本领域技术人员可以知道，辐射体2接受电磁波信号的波束指向与辐射体2发射电磁波信号的波束指向相同，所以辐射体2接受电磁波信号的方向也会随着辐射体2偏离于介质透镜12的焦点位置120的变化而变化。It should be noted that the above description shows that the direction of the electromagnetic wave beam radiated by the radiator 2 will change as the radiator 2 deviates from the focal position 120 of the dielectric lens 12. Those skilled in the art can know that the radiator 2 receives the electromagnetic wave signal. The beam direction is the same as the beam direction of the electromagnetic wave signal emitted by the radiator 2 , so the direction in which the radiator 2 receives the electromagnetic wave signal also changes as the radiator 2 deviates from the focal position 120 of the dielectric lens 12 .

进一步地，请参阅图6，当所述辐射体2相对所述介质透镜12的焦点位置120偏移时，所述矩形面122位于所述介质透镜12的焦点与所述半圆部125之间。Further, referring to FIG. 6 , when the radiator 2 is shifted relative to the focal position 120 of the dielectric lens 12 , the rectangular surface 122 is located between the focal point of the dielectric lens 12 and the semicircular portion 125 .

具体的，请参阅图5及图6，当对于偏焦形透镜天线而言，天线透镜1的矩形面122可以位于介质透镜12的焦点位置120与所述半圆部125之间，以使第二辐射体412靠近于弧形面121。当辐射体2与介质透镜12的焦点位置120在Y方向上的偏移距离相等时，辐射体2靠近于弧形面121的波束偏移角b2大于辐射体2远离于弧形面121的波束偏移角b1，以使辐射体2在Y轴方向上的偏离的距离较小，但从弧形面121射出的电磁波波束的指向相对于X轴方向偏转的较大，所以通过调节辐射体2在Y轴方向上的位置和X轴方向上的位置即可能够较大幅度地调节波束的偏移角度。Specifically, please refer to FIG. 5 and FIG. 6 , for a polarized lens antenna, the rectangular surface 122 of the antenna lens 1 can be located between the focal position 120 of the dielectric lens 12 and the semicircular portion 125 , so that the second The radiator 412 is close to the arc surface 121 . When the offset distance between the radiator 2 and the focal position 120 of the dielectric lens 12 in the Y direction is equal, the beam offset angle b2 of the radiator 2 close to the arc surface 121 is greater than the beam offset of the radiator 2 away from the arc surface 121 Offset angle b1, so that the deviation distance of the radiator 2 in the Y-axis direction is small, but the direction of the electromagnetic wave beam emitted from the arc surface 121 is deflected relatively large relative to the X-axis direction, so by adjusting the radiator 2 The position in the Y-axis direction and the position in the X-axis direction can greatly adjust the offset angle of the beam.

请参阅图7至图11，每个所述辐射体2相对于所述介质透镜12的焦点位置120的偏离位移不同，以使多个所述辐射体2辐射的电磁波信号经所述天线透镜1传导后射出的波束指向不同。Referring to FIGS. 7 to 11 , each of the radiators 2 has different offsets relative to the focal position 120 of the dielectric lens 12 , so that the electromagnetic wave signals radiated by the plurality of radiators 2 pass through the antenna lens 1 . The beams emitted after conduction are directed differently.

通过控制所述多个天线透镜1的辐射体2的位置不同，以使每个透镜天线单元14所辐射的波束指向不同，每个透镜天线单元14所辐射的波束指向相叠加形成透镜天线阵列10所辐射的波束扫描范围，进而使得透镜天线阵列10所辐射的波束扫描范围较大，提高电子设备100的天线性能。By controlling the positions of the radiators 2 of the plurality of antenna lenses 1 to be different, the beams radiated by each lens antenna unit 14 have different directions, and the beam directions radiated by each lens antenna unit 14 are superimposed to form the lens antenna array 10 The scanning range of the radiated beams further increases the scanning range of the beams radiated by the lens antenna array 10 , thereby improving the antenna performance of the electronic device 100 .

具体的，从所述透镜天线阵列10的中心至所述透镜天线阵列10的两端，每一个所述介质透镜12上的所述辐射体2相对于所述介质透镜12的焦点位置120的偏离位移逐渐增大，且位于所述透镜天线阵列10中心的天线透镜1两侧的辐射体2相对于所述介质透镜12的焦点位置的偏离方向相反。Specifically, from the center of the lens antenna array 10 to the two ends of the lens antenna array 10, the deviation of the radiator 2 on each of the dielectric lenses 12 relative to the focal position 120 of the dielectric lens 12 The displacement increases gradually, and the radiators 2 located on both sides of the antenna lens 1 in the center of the lens antenna array 10 deviate in opposite directions relative to the focal position of the dielectric lens 12 .

举例而言，位于所述透镜天线阵列10中心的天线透镜1的辐射体相对于所述介质透镜12的焦点位置的偏移量为零，位于所述透镜天线阵列10两侧的天线透镜1的辐射体相对于所述介质透镜12的焦点位置的偏移量逐渐增加，且两侧偏移方向相反。For example, the offset of the radiator of the antenna lens 1 located in the center of the lens antenna array 10 relative to the focal position of the dielectric lens 12 is zero, and the offset of the antenna lens 1 located on both sides of the lens antenna array 10 is zero. The offset of the radiator relative to the focal position of the dielectric lens 12 gradually increases, and the offset directions on both sides are opposite.

以所述多个天线透镜1沿所述半圆部125的直径所在方向(Y轴方向)排列为例进行说明。透镜天线阵列10在X－Y面内的波束扫描范围增加。可以理解的，所述多个天线透镜1还可以沿半圆部125的轴向(沿Z轴方向)排列。For example, the plurality of antenna lenses 1 are arranged along the direction of the diameter of the semicircular portion 125 (the Y-axis direction). The beam scanning range in the XY plane of the lens antenna array 10 is increased. It can be understood that the plurality of antenna lenses 1 may also be arranged along the axial direction of the semicircular portion 125 (along the Z-axis direction).

请参阅图7，所述透镜天线阵列10还包括切换开关15及射频收发芯片16。所述切换开关15电连接于所述射频收发芯片16与多个所述辐射体2之间。所述射频收发芯片16用于控制所述切换开关15依次导通多个辐射体2，并为对应的辐射体2提供激励信号，以实现波束扫描。Please refer to FIG. 7 , the lens antenna array 10 further includes a switch 15 and a radio frequency transceiver chip 16 . The switch 15 is electrically connected between the radio frequency transceiver chip 16 and the plurality of radiators 2 . The radio frequency transceiver chip 16 is used to control the switch 15 to turn on a plurality of radiators 2 in sequence, and provide excitation signals for the corresponding radiators 2 to realize beam scanning.

具体的，射频收发芯片16用于产生激励信号。切换开关15用于控制射频收发芯片16与多个所述辐射体2之间的路径的通断，以使射频收发芯片16产生的激励信号传输至对应的辐射体2，以激励对应的辐射体2向空间中辐射电磁波。举例而言，所述透镜天线单元14的数量为5个，每个辐射体2相对于天线透镜1的焦点的位置不同。通过切换所述切换开关15，以导通射频收发芯片16与第一个辐射体2，使得第一个所述透镜天线单元14沿第一指向辐射的波束；或者，导通射频收发芯片16与第二个辐射体2，使得第二个所述透镜天线单元14沿第二指向辐射的波束；或者，导通射频收发芯片16与第三个辐射体2，使得第三个所述透镜天线单元14沿第三指向辐射的波束；或者，导通射频收发芯片16与第四个辐射体2，使得第四个所述透镜天线单元14沿第四指向辐射的波束；或者，导通射频收发芯片16与第五个辐射体2，使得第五个所述透镜天线单元14沿第五指向辐射的波束。其中，第一指向、第二指向、第三指向、第四指向及第五指向皆不相同，以使透镜天线阵列10能够实现这五个指向的波束扫描。通过合理的设计透镜天线单元14的数量，以实现透镜天线阵列10波束扫描。Specifically, the radio frequency transceiver chip 16 is used to generate the excitation signal. The switch 15 is used to control the on-off of the path between the radio frequency transceiver chip 16 and the plurality of radiators 2, so that the excitation signal generated by the radio frequency transceiver chip 16 is transmitted to the corresponding radiator 2 to excite the corresponding radiator 2 Radiates electromagnetic waves into space. For example, the number of the lens antenna units 14 is 5, and the position of each radiator 2 relative to the focal point of the antenna lens 1 is different. By switching the switch 15, the RF transceiver chip 16 and the first radiator 2 are turned on, so that the first lens antenna unit 14 radiates the beam along the first direction; or, the RF transceiver chip 16 and the first radiator are turned on. the second radiator 2, so that the second lens antenna unit 14 radiates the beam along the second direction; or, the radio frequency transceiver chip 16 and the third radiator 2 are turned on, so that the third lens antenna unit 14 14 beams radiated along the third direction; or, turn on the radio frequency transceiver chip 16 and the fourth radiator 2, so that the fourth lens antenna unit 14 radiates beams along the fourth direction; or, turn on the radio frequency transceiver chip 16 and the fifth radiator 2, so that the fifth said lens antenna unit 14 radiates the beam along the fifth direction. The first direction, the second direction, the third direction, the fourth direction and the fifth direction are all different, so that the lens antenna array 10 can realize the beam scanning of these five directions. The beam scanning of the lens antenna array 10 can be realized by reasonably designing the number of the lens antenna units 14 .

通过切换所述切换开关15可以调节所述透镜天线阵列10所辐射波束的指向，以使所述透镜天线阵列10能够定向辐射电磁波波束，使得所述透镜天线阵列10所辐射波束的指向随着用户运动、转动而调节，透镜天线阵列10可以通过切换开关15实现波束扫描，使所述透镜天线阵列10与接收装置之间保持良好的信号传输，提高电子设备100的通讯质量，不需要移向器和衰减器，大大降低了成本。By switching the switch 15, the direction of the beam radiated by the lens antenna array 10 can be adjusted, so that the lens antenna array 10 can radiate the electromagnetic wave beam directionally, so that the direction of the beam radiated by the lens antenna array 10 follows the direction of the user. The lens antenna array 10 can be adjusted by moving and rotating, and the beam scanning can be realized by switching the switch 15, so that good signal transmission between the lens antenna array 10 and the receiving device can be maintained, and the communication quality of the electronic device 100 can be improved, and no direction shifter is required. and attenuators, greatly reducing the cost.

The second lens antenna unit 41 includes a second antenna lens 411 and a second radiator 412 . The second antenna lens 411 includes the second dielectric lens 18 . It can be understood that the structure of the second antenna lens 411 may be the same as that of the first antenna lens 311 . The second radiator 412 is fixed on the rectangular surface 122 of the second antenna lens 411 , and the second radiator 412 is located between the center of the rectangular surface 122 of the second antenna lens 411 and the first radiator 312 . The center position of the rectangular surface 122 of the second antenna lens 411 is the focal position 181 of the second dielectric lens 18 . The second radiator 412 is separated from the focal position 181 of the second dielectric lens 18 by a first distance L1.

当切换开关15导通射频收发芯片16与第二辐射体412时，第二辐射体412辐射的电磁波信号经第二天线透镜411折射之后从弧形面121射出的波束指向逐渐远离所述第一透镜天线单元31的中轴线127，且第二辐射体412辐射的波束指向与X轴方向之间的夹角为第一角度a1。When the switch 15 turns on the radio frequency transceiver chip 16 and the second radiator 412, the electromagnetic wave signal radiated by the second radiator 412 is refracted by the second antenna lens 411 and the beam emitted from the arc surface 121 is directed away from the first The included angle between the central axis 127 of the lens antenna unit 31 and the direction of the beam radiated by the second radiator 412 and the X-axis direction is the first angle a1.

第二透镜天线单元41也称为偏焦形透镜天线。偏焦形透镜天线的辐射体2的相位中心与透镜焦点所在中轴线127有相对偏移第一距离L1。通过调整第一距离L1的大小，可以改变偏焦形透镜天线辐射波束的指向，偏焦形透镜天线的辐射波束指向与偏焦形透镜天线的中轴线127的夹角为第一角度a1，第一距离L1越大，第一角度a1越大。The second lens antenna unit 41 is also referred to as a defocus-shaped lens antenna.
