The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0052] The accompanying drawings, which are included to provide a further understanding of the present disclosure and constitute a part of this specification, illustrate embodiments of the present disclosure and together with the detailed description serve to explain the present disclosure. The above and other features and advantages of the present disclosure will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings.

Therefore, the example illustrations can not be necessarily drawn to scale and the dimensions of the different elements can be exaggerated and / or simplified in the example illustrations.

[0054] The embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0055] The terminology used by the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used in the present disclosure, the term "and / or" includes any and all combinations of one or more of the associated listed items. As used in the present disclosure, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used in the present disclosure, the terms "comprises," "comprising," "consisting of," and "consisting essentially of" specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0057] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configuration formed based on the manufacturing process. Therefore, the regions exemplified in the drawings have a schematic property, and the shape of the regions shown in the drawings exemplifies a specific shape of the region of the element, but is not intended to be restrictive.

[0058] With the increasing number of mobile communication systems and frequency bands, the number of antenna units required to process wireless resources is also increasing, so that in the case of site sharing, many antenna units need to be set in a base station, resulting in a large load burden of the base station tower, insufficient space for antenna unit layout, large overall volume, and serious visual pollution.

[0059] In some related technologies, an antenna unit with multiple working gears can be used, that is, an adjusting device is provided in the antenna unit, and by changing the position of the adjusting device, the actual structure of the antenna unit can be changed accordingly, and then the phase angle, beam width and other parameters of the antenna unit can be changed, so that it is in different working gears. Thus, one antenna unit can be switched to the corresponding working gear according to the specific needs at different times to process the wireless resources of the corresponding system and frequency band, thereby reducing the number of antenna units required.

[0060] To improve the integration, multiple antenna units can be provided in one antenna device, and the adjusting devices of these antenna units can be driven by a multiple antenna gear shifting device, that is, the working gears of the multiple antenna units can be controlled by the multiple antenna gear shifting device.

[0061] To this end, the embodiments of the present disclosure provide a new multiple antenna gear shifting device.

[0062] In a first aspect, with reference to Figures 1 to 11, an embodiment of the present disclosure provides a multi-channel antenna shifting device.

[0063] Reference Figure 1 In the disclosed embodiment, the antenna device includes multiple antenna units 8. Each antenna unit 8 is an antenna structure capable of relatively independent processing of wireless resources, and includes an adjustment device 81. By changing the position of adjustment device 81, the actual structure of antenna unit 8 can be changed accordingly, thereby changing parameters such as the phase angle and beamwidth of antenna unit 8, thereby switching the antenna unit 8 between different operating modes.

[0064] In some embodiments, the adjustment device 81 includes at least one of the following: a phase shifter slider; and an isolation strip.

[0065] As one embodiment of the present disclosure, the adjustment device 81 may include a phase shifter slide, that is, a sliding adjustment structure in the phase shifter of the antenna unit 8. By changing the position of the phase shifter slide, the phase angle of the antenna unit 8 can be adjusted.

[0066] Alternatively, as another embodiment of the present disclosure, the adjustment device 81 of the antenna unit 8 may also include an isolation strip, which may be arranged on the array surface of the antenna unit 8, so that the beam width of the antenna unit 8 can be adjusted by changing the position of the isolation strip.

[0067] It should be understood that the adjustment device 81 in the embodiment of the present disclosure is not limited to the above-mentioned forms of phase shifter slides and isolation strips, and the parameters that can be adjusted in the antenna unit 8 are not limited to the above-mentioned phase angle and beam width.

[0068] Reference Figure 1 The multi-channel antenna shifting device of the embodiment of the present disclosure is arranged in the above antenna equipment and is respectively connected to the adjustment device 81 of each antenna unit 8, so it can independently drive the adjustment device 81 of each antenna unit 8 to move to the desired position, that is, independently switch the working gear of each antenna unit 8 to realize "multi-channel antenna shifting".

[0069] It should be understood that the antenna device of the embodiment of the present disclosure includes, in addition to the above antenna unit 8 and the multi-channel antenna shifting device, other structures, such as a radio frequency circuit for processing signals, an input device for controlling the multi-channel antenna shifting device, etc., which will not be described in detail here.

[0070] Reference Figures 2 to 4 The multi-path antenna shifting device of the embodiment of the present disclosure includes:

[0071] A plurality of movable racks 1 extending along a first direction 91, the movable racks 1 being used to connect to the adjustment device 81 of the antenna unit 8; the plurality of movable racks 1 are arranged side by side along a second direction 92 intersecting the first direction 91, and the teeth of all movable racks 1 are oriented in the same direction;

[0072] The shift rack 2 is arranged at the side of each movable rack 1 where the teeth are located, and extends along the second direction 92. The teeth of the shift rack 2 are arranged at the side away from the movable rack 1, and the shift rack 2 is provided with the engaging teeth 291 at the side facing the movable rack 1, which are matched with the teeth of the movable rack 1.

[0073] The first driving unit is configured to drive the shift rack 2 to move along the second direction 92, so that the engaging teeth 291 are engaged with the teeth of the movable rack 1 to be adjusted.

[0074] The second driving unit is configured to drive the shift rack 2 to move along the first direction 91, so as to drive the movable rack 1 to be adjusted to move along the first direction 91.

[0075] Referring to Figures 2 to 4 The multi-path antenna shift device according to the embodiments of the present disclosure comprises a plurality of movable racks 1, each of which is directly or indirectly connected to the adjusting device 81 of the antenna unit 8. For example, the movable rack 1 can be connected to the adjusting device 81 through the connecting member 71. In this way, when the movable rack 1 moves, the corresponding adjusting device 81 can be driven to move, so as to realize the working gear shift of the antenna unit 8. Figure 3

[0076] The first direction 91 and the second direction 92 can be perpendicular to each other, for example, as shown in FIG. 1. Figure 2

[0077] The multi-path antenna shift device further comprises a shift rack 2 extending along the second direction 92. The shift rack 2 is arranged at the side of each movable rack 1 where the teeth are located, and the teeth of the shift rack 2 are arranged at the side away from the movable rack 1, and the shift rack 2 is provided with the engaging teeth 291 at the side facing the movable rack 1, which are matched with the teeth of the movable rack 1.

[0078] The first driving unit is configured to drive the shift rack 2 to move along the second direction 92, so that the engaging teeth 291 are engaged with the teeth of the movable rack 1 to be adjusted. The second driving unit is configured to drive the shift rack 2 to move along the first direction 91, so as to drive the movable rack 1 to be adjusted to move along the first direction 91.

[0079] ​​The multi-path antenna gear device of the embodiment of the present disclosure can drive the gear shifting rack 2 to move by the first driving unit to select the moving rack 1 to be adjusted, that is, to select the antenna unit 8 to be adjusted; and then drive the gear shifting rack 2 and the moving rack 1 to be adjusted to move together by the second driving unit, that is, drive the adjusting device 81 of the antenna unit 8 to be adjusted to move, so as to adjust the working gear of the antenna unit 8; wherein, since the gear shifting rack 2 moves together with the moving rack 1 in the embodiment of the present disclosure, compared with the way that the gear shifting structure does not move while the moving structure moves in the related art, the number of devices in the multi-path antenna gear device of the embodiment of the present disclosure is less, the structure is simple, the volume is small, and the cost is low.

[0080] With reference to Figure 5 , Figure 6 In some embodiments, the gear shifting rack 2 has two clamping teeth 291, respectively located at both ends of the gear shifting rack 2 along the second direction 92; the distance between the two clamping teeth 291 is greater than the distance between the two farthest moving racks 1 in the second direction 92.

[0081] As a way of the embodiment of the present disclosure, with reference to Figure 5 , Figure 6 The gear shifting rack 2 can be provided with one clamping tooth 291 at each end, and the distance between the clamping teeth 291 at both ends is greater than the distance between the two farthest moving racks 1, so that no matter where the gear shifting rack 2 moves to, the two clamping teeth 291 will not be engaged with the moving rack 1 at the same time, but can “uniquely” select the moving rack 1 to be adjusted. Thus, the two clamping teeth 291 of the gear shifting rack 2 can each be responsible for engaging with a part of the moving rack 1, for example, about “half” of the moving rack 1; thus, compared with the way of having only one clamping tooth 291, the gear shifting rack 2 only needs to move in a smaller range in the second direction 92, so that any moving rack 1 can be engaged with the clamping tooth 291, so as to reduce the requirements on the first driving unit.

[0082] With reference to Figure 4 , Figure 5 In some embodiments, the gear shifting rack 2 is arranged in the gear shifting guide frame 21, and the side of the gear shifting guide frame 21 facing the moving rack 1 is provided with a first opening 2191, and the clamping tooth 291 extends out of the gear shifting guide frame 21 through the first opening 2191;

[0083] The first driving unit is used to drive the gear shifting rack 2 to move in the gear shifting guide frame 21 along the second direction 92;

[0084] The second driving unit is used to drive the gear shifting guide frame 21 to move along the first direction 91.

[0085] As a way of the embodiment of the present disclosure, with reference to Figure 5The shift rack 2 can be set in a shift guide frame 21 that serves as a guide. The shift guide frame 21 has a first opening 2191 on the side facing the movable rack 1, so that the engaging tooth 291 of the shift rack 2 can extend from the first opening 2191 and engage with the movable rack 1.

[0086] Reference Figure 4 The shift guide frame 21 is fixed in the second direction 92. Therefore, the shift rack 2 can move relative to the shift guide frame 21 under the drive of the first drive unit, that is, move in the second direction 92. The second drive unit can drive the "entire" shift guide frame 21 to move in the first direction 91, that is, drive the shift rack 2 therein to move in the first direction 91.

[0087] In the above manner, the independent movement of the shift guide frame 21 in the first direction 91 and the second direction 92 can be achieved with a simple structure.

[0088] Reference Figure 3 、 Figure 4 In some embodiments, the first driving unit includes a first motor 31 , the output shaft of the first motor 31 is connected to a shift gear 311 , and the teeth of the shift gear 311 are engaged with the teeth of the shift rack 2 ;

[0089] The second drive unit includes a second motor 32 , the output shaft of the second motor 32 is connected to a shift screw 321 extending along the first direction 91 , the shift screw 321 passes through the shift guide frame 21 , and the shift guide frame 21 is provided with an internal thread engaged with the external thread of the shift screw 321 .

[0090] As one embodiment of the present disclosure, refer to Figure 3 、 Figure 4 The first drive unit may include a first motor 31, and the output shaft of the first motor 31 is externally mounted with a shift gear 311, such as a spur gear. The teeth of the shift gear 311 mesh with the teeth of the shift rack 2. For example, the first motor 31 may be mounted on the shift guide frame 21 so that it moves along with the shift guide frame 21. The shift gear 311 connected to the first motor 31 is mounted within the shift guide frame 21 and meshes with the shift rack 2. Thus, when the first motor 31 is operating, the shift gear 311 rotates, thereby driving the shift rack 2 to move within the shift guide frame 21 in the second direction 92.

[0091] Reference Figure 3 、 Figure 4The second driving unit can be a second motor 32, an output shaft of the second motor 32 is connected to a shift screw 321 extending in the first direction 91, for example, the output shaft is sleeved with the shift screw 321, the shift screw 321 passes through the shift guide frame 21, and an external thread of the shift screw 321 matches an internal thread of the shift guide frame 21. For example, the second motor 32 can be fixedly arranged relative to a base 79, and the base 79 is used to support other structures, so that the second motor 32 is also fixed relative to the other structures, the shift screw 321 connected to the second motor 32 can pass through the middle of the shift guide frame 21, and the shift guide frame 21 can also be passed through by a plurality of guide rods 72 arranged on the base 79, so as to ensure that the shift guide frame 21 cannot rotate. Thus, when the second motor 32 works, the shift screw 321 rotates, that is, the shift guide frame 21 and the shift rack 2 in the shift guide frame 21 are driven to move in the first direction 91.

[0092] In the foregoing manner, the movement of the shift rack 2 in two directions is independently driven by two motors respectively, that is, complete decoupling of the movement in two directions is realized, and the control difficulty is greatly reduced, the product structure is simplified, the size is reduced, and the reliability is improved.

[0093] In addition, in the foregoing manner, the direct cooperation of the shift gear 311 and the shift rack 2 and the direct cooperation of the shift screw 321 and the shift guide frame 21 respectively realize the driving in the second direction 92 and the first direction 91, compared with the driving mode of the gear pair in the related art, the structure is simple, the size is small, the cost is low, and the reliability is good.

[0094] Referring to Figure 1 , Figure 2 , Figure 7 In some embodiments, each moving rack 1 has a corresponding locking unit 4, and the locking unit 4 is used to fix the position of the corresponding moving rack 1 when the corresponding moving rack 1 is not the moving rack 1 to be adjusted.

[0095] According to the embodiments of the present disclosure, the teeth of the current moving rack 1 to be adjusted are engaged with the engagement teeth 291 of the shift rack 2, so that the current moving rack 1 to be adjusted can be driven by the shift rack 2 to move in the first direction 91, so as to realize the working gear adjustment of the antenna unit 8 to be adjusted; and the working gears of other “non-adjusted” antenna units 8 should be fixed and unchanged.

[0096] Therefore, as one of the embodiments of the present disclosure, referring to Figure 1 , Figure 2 , Figure 7 Each moving rack 1 can also be provided with a corresponding locking unit 4, and the locking unit 4 is used to relatively fix the position of the corresponding moving rack 1 when the corresponding moving rack 1 is not the moving rack 1 to be adjusted, so as to ensure that the position of the corresponding adjusting device 81 is fixed, and the working gear of the antenna unit 8 remains unchanged.

[0097] It should be understood that when the mobile rack 1 is selected as the mobile rack 1 to be adjusted, the corresponding locking unit 4 can also "unlock" the mobile rack 1 to allow better movement of the mobile rack 1.

[0098] Referring to Figures 7 to 10 In some embodiments, along the second direction 92, the locking unit 4 is located on one side of the corresponding mobile rack 1;

[0099] Each mobile rack 1 is arranged in a mobile guide frame 11, and the mobile guide frame 11 is provided with a second opening 1192 on the side facing the shift rack 2, and the mobile guide frame 11 is provided with a first side wall 111 on the side away from the corresponding locking unit 4;

[0100] The locking unit 4 is used to apply pressure to the corresponding mobile rack 1 when the mobile rack 1 is not the mobile rack 1 to be adjusted, so as to press the mobile rack 1 against the first side wall 111 of the mobile guide frame 11 where the mobile rack 1 is located.

[0101] As one of the embodiments of the present disclosure, referring to Figures 7 to 10 The mobile rack 1 can be arranged in a mobile guide frame 11 that plays a guiding role, referring to Figure 10 The mobile guide frame 11 is provided with a second opening 1192 on the side facing the shift rack 2, so that the engagement teeth 291 of the shift rack 2 can be inserted to engage with the teeth of the mobile rack 1. In this case, referring to Figure 7 、 Figure 10 Along the second direction 92, the locking unit 4 can be arranged on one side of the corresponding mobile rack 1, and the locking unit 4 can "press" the mobile rack 1 to the other side when the mobile rack 1 is not the mobile rack 1 to be adjusted, so as to press the mobile rack 1 against the first side wall 111 of the mobile guide frame 11, thereby fixing the position of the mobile rack 1.

[0102] Referring to Figures 8 to 10 In some embodiments, the locking unit 4 comprises:

[0103] A locking frame 41, which is provided with a third opening 4193 on the side facing the shift rack 2, a bottom wall 419 opposite to the third opening 4193, and a second side wall 412 away from the corresponding mobile rack 1;

[0104] A first sliding block 421 arranged in the locking frame 41 and in contact with the second side wall 412;

[0105] A first elastic member 431 arranged between the first sliding block 421 and the bottom wall 419, used to apply a force away from the bottom wall 419 to the first sliding block 421;

[0106] The second slider 422 is arranged in the locking frame 41 and contacts the first slider 421 away from one side of the second side wall 412, and the side of the second slider 422 away from the first slider 421 is used to apply pressure to the corresponding movable rack 1; the contact surface of the second slider 422 and the first slider 421 forms a sliding pair, and the structure of the sliding pair is configured to allow the second slider 422 to move towards the second side wall 412 when the first slider 421 moves towards the bottom wall 419.

[0107] Wherein, referring to Figure 6 、 Figure 11 , the shift rack 2 further has an unlocking pressure head 292 corresponding to the clamping tooth 291 on the side facing the movable rack 1, and the structure of the unlocking pressure head 292 is configured to apply a force directed to the bottom wall 419 to the first slider 421 of the corresponding locking unit 4 when the corresponding clamping tooth 291 is engaged with any movable rack 1.

[0108] As one of the embodiments of the present disclosure, referring to Figure 8 、 Figure 10 , the locking unit 4 can include a locking frame 41, and the locking frame 41 has a third opening 4193 on the side facing the shift rack 2, and the opposite side of the third opening 4193 is the bottom wall 419; the locking frame 41 is provided with a second side wall 412 on the side away from the corresponding movable rack 1, and the second side wall 412 can be connected with the bottom wall 419, so that the cross section of the locking frame 41 can form a structure similar to "L shape".

[0109] Referring to Figure 8 、 Figure 10 , the first slider 421 and the second slider 422 are further arranged in the locking frame 41.

[0110] Wherein, referring to Figure 10 , the first slider 421 contacts the second side wall 412 on one side, and is connected with the bottom wall 419 through one or more first elastic members 431, and the first elastic member 431 can apply a force away from the bottom wall 419 to the first slider 421, that is, a force pushing the first slider 421 away from the bottom wall 419. The second slider 422 is located between the corresponding movable rack 1 and the first slider 421, and the side of the second slider 422 facing the movable rack 1 can apply pressure to the movable rack 1 to press the movable rack 1 against the first side wall 111 of the movable guide frame 11. At the same time, the side of the second slider 422 facing the side wall of the first slider 421 also contacts the first slider 421 and forms a "sliding pair", and through the action of the sliding pair, when the first slider 421 moves towards the bottom wall 419, the second slider 422 moves towards the second side wall 412; correspondingly, when the first slider 421 moves away from the bottom wall 419, the second slider 422 also moves away from the second side wall 412.

[0111] Further, referring to Figure 6, the side where the engaging teeth 291 of the shift rack 2 are located is also provided with an unlocking pressure head 292 corresponding to each engaging tooth 291; and referring to Figure 11 The relative positions of the unlocking pressure head 292 and the engaging tooth 291 corresponding to each other can ensure that when the engaging tooth 291 engages with the tooth of a certain movable rack 1, the corresponding unlocking pressure head 292 can be pressed against the first sliding block 421 on the side away from the bottom wall 419 of the locking frame 41 through the third opening 4193 of the locking frame 41 corresponding to the movable rack 1.

[0112] Referring to Figures 8 to 10 In some embodiments, the locking unit 4 further comprises:

[0113] A second elastic member 432 is configured to apply a force to the second sliding block 422 towards the first sliding block 421.

[0114] As one of the embodiments of the present disclosure, referring to Figure 10 A second elastic member 432 can also be provided to apply a force to the second sliding block 422 towards the first sliding block 421, that is, to press the second sliding block 422 towards the first sliding block 421, so as to better ensure that the second sliding block 422 can release the movable rack 1 in the unlocked state.

[0115] Therefore, the locking unit 4 of the embodiment of the present disclosure can work in the following ways:

[0116] (1) Referring to Figure 10 When a certain movable rack 1 is not the movable rack 1 to be adjusted, the shift rack 2 is not at its corresponding position, and the first sliding block 421 of the corresponding locking unit 4 does not contact the unlocking pressure head 292, so the first elastic member 431 can push the first sliding block 421 away from the bottom wall 419 of the locking frame 41, and the first sliding block 421 pushes the second sliding block 422 towards the movable rack 1, and the second sliding block 422 presses the movable rack 1 against the first side wall 111 of the shift guide frame 21 with a larger force, so that the movable rack 1 is positioned and cannot move in the shift guide frame 21, achieving “locking”.

[0117] (2) Referring to Figure 11 When a certain movable rack 1 is the movable rack 1 to be adjusted, the tooth thereof engages with the engaging tooth 291 of the shift rack 2, and the unlocking pressure head 292 corresponding to the engaging tooth 291 presses the first sliding block 421 corresponding to the movable rack 1, compressing the first elastic member 431 and causing the first sliding block 421 to move towards the bottom wall 419 of the locking frame 41; further, the second sliding block 422 has a space to move towards the second side wall 412 of the locking frame 41, and is away from the movable rack 1 under the action of the second elastic member 432 and releases the movable rack 1 from the first side wall 111 of the shift guide frame 21, so that the movable rack 1 to be adjusted is “unlocked” and can move in the shift guide frame 21.

[0118] According to the above form of the locking unit 4, the movable rack 1 can be locked or unlocked by the "damping" effect of the elastic member, which has high reliability, high efficiency and good stability compared with the passive locking structure using silica gel pad and the like in the related art.

[0119] With reference to Figure 11 In some embodiments, the first slider 421 is provided with an unlocking protrusion 4211 on the side away from the bottom wall 419.

[0120] The unlocking protrusion 4211 is configured to apply a force to the first slider 421 directed to the bottom wall 419 through the unlocking protrusion 4211 when the corresponding engagement tooth 291 of the unlocking ram 292 is engaged with the teeth of any movable rack 1.

[0121] As one of the embodiments of the present disclosure, with reference to Figure 11 The first slider 421 can also be provided with an unlocking protrusion 4211 on the side away from the bottom wall 419, and the unlocking ram 292 of the shift rack 2 can apply a force to the first slider 421 by contacting the unlocking protrusion 4211. Thus, since the position of the unlocking protrusion 4211 is more prominent than the "other" position of the first slider 421, the unlocking ram 292 is not easy to contact the "other" position, and accidental "unlocking" can be avoided.

[0122] It should be understood that the specific form of the locking unit 4 of the embodiments of the present disclosure is various.

[0123] For example, with reference to Figure 10 , Figure 11 The first elastic member 431 can be in the form of a spring, which is arranged in a compressed state between the first slider 421 and the bottom wall 419, so as to push the first slider 421 away from the bottom wall 419. Alternatively, the first elastic member 431 can also be in other forms such as a spring.

[0124] For another example, with reference to Figure 10 , Figure 11 The second elastic member 432 can be in the form of a spring, such as a coil spring, which is arranged in a compressed state between the third side wall 113 of the movable guide frame 11 facing the locking unit 4 and the second slider 422, so as to push the second slider 422 towards the second side wall 412. Alternatively, the second elastic member 432 can also be in the form of a spring that "pulls" the second slider 422 towards the second side wall 412.

[0125] For another example, with reference to Figure 10 , Figure 11The locking frame 41 can be "open" toward the side of the moving guide frame 11, and the moving guide frame 11 can have the third side wall 113 toward the side of the locking frame 41. The third side wall 113 can have a plurality of holes for the push rods 4221 of the second sliders 422 to pass through, so that the second sliders 422 can apply pressure to the moving rack 1 through the push rods 4221. For example, the spring of the second elastic member 432 can be sleeved outside the push rod 4221, so as to be arranged between the second slider 422 and the third side wall 113. Alternatively, the moving guide frame 11 can be open toward the side of the locking frame 41, and the locking frame 41 can have a side wall with holes toward the side of the moving guide frame 11, so that the second elastic member 432 can be arranged between the side wall with holes and the second slider 422.

[0126] For example, referring to Figure 10 、 Figure 11 The side surface of the first slider 421 and the second slider 422 in contact with each other can be two inclined surfaces, such as two inclined surfaces inclined at an angle of 45 degrees with respect to the bottom wall 419, so as to form the sliding pair. Alternatively, the sliding pair between the first slider 421 and the second slider 422 can be an arc surface or other forms.

[0127] For example, referring to Figure 6 The unlocking pressure head 292 can be connected to the corresponding engagement tooth 291. Alternatively, the unlocking pressure head 292 and the engagement tooth 291 can be directly connected to the shift rack 2, respectively.

[0128] In a second aspect, referring to Figures 1 to 11 The present disclosure provides an antenna device.

[0129] The present disclosure provides an antenna device comprising the multi-path antenna shift device.

[0130] For example, referring to Figure 1 The antenna device of the present disclosure comprises:

[0131] The multi-path antenna unit 8 comprises an adjusting device 81 for switching the working gear of the antenna unit 8 by changing the position.

[0132] The adjusting device 81 of the multi-path antenna unit 8 comprises at least one of the following: a phase shifter slide; an isolation strip.

[0133] In some embodiments, the adjusting device 81 comprises at least one of the following: a phase shifter slide; an isolation strip.
