[0017] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

For example, some operations / steps can be decomposed, combined or partially merged, and therefore the actual execution order can be changed according to the actual situation.
[0019] It should be understood that the terms used in the present application description herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present application description and the appended claims, unless otherwise clear from the context, the singular forms "a", "an" and "the" are intended to include the plural forms.
[0020] The embodiments of the present application provide an antenna control method, a control terminal and a communication system. The antenna control method is applied to the control terminal, the antenna includes an antenna module and a pose adjusting device connected with the antenna module, and the control terminal is electrically connected with the antenna.
[0021] Some embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
[0022] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the control terminal provided by the embodiments of the present application is electrically connected with the antenna.
[0023] As Figure 1 shown, the control terminal 1 is electrically connected with the antenna 2, wherein the antenna 2 includes an antenna module 20 and a pose adjusting device 21. Specifically, the antenna module 20 is connected with the pose adjusting device 21, and the control terminal 1 is electrically connected with the antenna module 20 and the pose adjusting device 21 when electrically connected with the antenna 2. The control terminal 1 transmits and receives signals through the antenna module 20, and controls the pose adjusting device 21 to adjust the pose of the antenna module.
[0024] In some embodiments, the pose adjusting device 21 can be a one-dimensional rotating device. The antenna module 20 can be driven to rotate in a certain rotating plane by the pose adjusting device 21. For example, the rotating plane can be a horizontal plane, a pitch plane perpendicular to the horizontal plane, or another inclined plane not perpendicular to the horizontal plane, which is not limited herein.
[0025] In some embodiments, the pose adjusting device 21 can also be a two-dimensional rotating device, by which the antenna module 20 can be rotated in two rotating planes; in addition, the pose adjusting device 21 can also be a rotating device of more dimensions, which is not limited here.
[0026] In some embodiments, the control terminal 1 forms a CPE (Customer Premise Equipment) product when it is in electrical communication connection with the antenna 2, and the control terminal can provide network services for other terminal devices through wired or wireless means.
[0027] Please refer to Figure 2 , Figure 2 A flowchart of an antenna control method applied to a control terminal according to an embodiment of the present application is provided.
[0028] As Figure 2 shown, the antenna control method includes steps S10 to S12.
[0029] Step S10, obtaining a directional diagram of the antenna module, and determining a first rotating step of the pose adjusting device in a rotating direction according to a main lobe of the directional diagram.
[0030] It can be understood that the directional diagram of the antenna module 20, i.e., the radiation directional diagram of the antenna module 20, is a graphical description of the radiation characteristics of the antenna module 20. There are usually two lobes or multiple lobes in the directional diagram, wherein the largest lobe is called the main lobe, and the remaining lobes are called side lobes or side lobes. The side lobe in the opposite direction of the main lobe is called the back lobe.
[0031] The first rotating step is a unit angle of the pose adjusting device for adjusting the pose of the antenna module. In some embodiments, the first rotating step refers to the angle between the two points on both sides of the main lobe maximum radiation direction in the reference plane, when the radiation intensity decreases to a preset value, after determining that the plane in which the rotating direction of the pose adjusting device is located as the reference plane, and taking the main lobe maximum radiation direction as the center.
[0032] The first rotating step can include one or more rotating steps, and the first rotating step corresponds to the rotating direction of the pose adjusting device 21. For example, when the pose adjusting device 21 is a one-dimensional rotating device, the first rotating step includes one rotating step, which corresponds to the rotating direction of the pose adjusting device 21. When the pose adjusting device 21 is a two-dimensional rotating device, the first rotating step includes two rotating steps, which respectively correspond to the two rotating directions of the pose adjusting device 21.
[0033] In some embodiments, the pose adjusting device comprises a horizontal rotation component for rotating the antenna module in a horizontal direction, and a pitch rotation component for rotating the antenna module in a pitch direction.
[0034] The first rotation step of the pose adjusting device in the rotation direction is determined according to the main lobe of the directional diagram, comprising:
[0035] The half-power lobe width of the main lobe of the directional diagram in the horizontal plane is obtained as the first horizontal step, and the half-power lobe width of the main lobe in the pitch plane is obtained as the first pitch step.
[0036] It can be understood that when determining the first horizontal step corresponding to the horizontal rotation component, because the plane in which the horizontal rotation component rotates is the horizontal plane, the horizontal plane is set as the reference plane, and the half-power lobe width of the main lobe in the horizontal plane is obtained as the first horizontal step. Similarly, when determining the first pitch step corresponding to the pitch rotation component, because the plane in which the pitch rotation component rotates is the pitch plane, the pitch plane is set as the reference plane, and the half-power lobe width of the main lobe in the pitch plane is obtained as the first pitch step.
[0037] The half-power lobe width refers to, after determining the reference plane, the included angle between the two points on both sides of the main lobe maximum radiation direction in the reference plane, with the maximum radiation direction as the center, and the radiation intensity of the two points is reduced to half of the maximum radiation intensity.
[0038] In some embodiments, the antenna module 20 can be connected with the horizontal rotation component, and in addition, the antenna module 20 can also be connected with the pitch rotation component, which is not limited here.
[0039] Please refer to Figure 3 , Figure 3 A structural schematic diagram of an antenna provided by an embodiment of the present application.
[0040] As Figure 3 shown, the pose adjusting device 21 adjusts the pose of the antenna module 20 through the horizontal rotation component 210 and the pitch rotation component 211. The pitch rotation component 211 is connected with the antenna module 20, and the pitch rotation component 211 can drive the antenna module 20 to rotate in the pitch direction. The horizontal rotation component 210 is connected with the pitch rotation component 211, and in the process of driving the pitch rotation component 211 to rotate in the horizontal direction through the horizontal rotation component 210, the antenna module 20 can be indirectly driven to rotate in the horizontal direction.
[0041] In step S11, a first rotation range of the pose adjustment device in the rotation direction is obtained, and the pose adjustment device is controlled to adjust the pose of the antenna module in the first rotation range according to the first rotation step, and a first signal strength of the antenna module in each pose is obtained.
[0042] It can be understood that the angle range in which the pose adjustment device 21 can rotate in the rotation direction is the first rotation range. After the first rotation range and the first rotation step are determined, the pose adjustment device 21 can be controlled to rotate in the first rotation range according to the first rotation step, so as to adjust the pose of the antenna module 20.
[0043] When the pose of the antenna module 20 changes, the signal strength of the antenna module 20 also changes. When the pose of the antenna module 20 is adjusted by taking the first rotation step as the unit rotation step of the pose adjustment device 21, the signal strength of the antenna module 20 recorded in each pose is the first signal strength.
[0044] For example, assuming that the pose adjustment device 21 is a one-dimensional rotation device, the first rotation range is 0°-60°, and the first rotation step is 20°, the pose adjustment device 21 is controlled to rotate to 0°, 20°, 40° and 60° respectively. During the process in which the pose of the antenna module 20 is adjusted by the pose adjustment device 21 in the first rotation range according to the first rotation step, the first signal strength recorded includes the signal strength of the antenna module 20 when the pose adjustment device 21 rotates to 0°, the signal strength of the antenna module 20 when the pose adjustment device 21 rotates to 20°, the signal strength of the antenna module 20 when the pose adjustment device 21 rotates to 40°, and the signal strength of the antenna module 20 when the pose adjustment device 21 rotates to 60°.
[0045] In some embodiments, the signal strength of the antenna module 20 can be the gain of the antenna module 20, can be the EIRP (Effective Isotropic Radiated Power) of the antenna module, or can be other parameters that can represent the signal quality of the antenna module, which is not limited herein.
[0046] In some embodiments, the obtaining of the first rotation range of the pose adjustment device in the rotation direction, the controlling of the pose adjustment device to adjust the pose of the antenna module in the first rotation range according to the first rotation step, and the obtaining of the first signal strength of the antenna module in each pose include:
[0047] A rotatable range of the horizontal rotation component in the horizontal direction is obtained as the first horizontal rotation range, and a rotatable range of the pitch rotation component in the pitch direction is obtained as the first pitch rotation range.
[0048] controlling the horizontal rotating component to rotate the antenna module horizontally in the first horizontal rotating range according to the first horizontal step size, and controlling the pitching rotating component to rotate the antenna module in the first pitching rotating range according to the first pitching step size, so as to adjust the pose of the antenna module;
[0049] recording the signal strength of the antenna module in each pose as a first signal strength.
[0050] It can be understood that the angle range that the horizontal rotating component 210 can rotate in the horizontal direction is the first horizontal rotating range, and correspondingly, the angle range that the pitching rotating component 211 can rotate in the pitching direction is the first pitching rotating range.
[0051] After determining the first horizontal rotating range and the first horizontal step size, the horizontal rotating component 210 can be controlled to drive the antenna module 20 to rotate horizontally in the first horizontal rotating range with the first horizontal step size as the rotating step size. Correspondingly, after determining the first pitching rotating range and the first pitching step size, the pitching rotating component 211 can be controlled to drive the antenna module 20 to rotate in the first pitching rotating range with the first pitching step size as the rotating step size. In this process, the signal strength of the antenna module 20 in each pose is recorded as a first signal strength. The number of the first signal strength matches the number of the poses of the antenna module 20.
[0052] For example, it is assumed that the first horizontal rotating range is 0° to 360°, the first horizontal step size is 120°, the first pitching rotating range is 0° to 45°, and the first pitching step size is 15°. In the first horizontal rotating range and the first pitching rotating range, the rotating combination of the horizontal rotating component 210 and the pitching rotating component 211 and the number of the first signal strength are shown in Table 1.
[0053] Table 1,
[0054] Horizontal rotation assembly Pitch rotation assembly First signal strength 0° 0° Signal strength 1a 120° 0° Signal strength 2a 240° 0° Signal strength 3a 0° 15° Signal strength 4a 120° 15° Signal strength 5a 240° 15° Signal strength 6a 0° 30° Signal strength 7a 120° 30° Signal strength 8a 240° 30° Signal strength 9a 0° 45° Signal strength 10a 120° 45° Signal strength 11a 240° 45° Signal strength 12a
[0055] In step S12, a first target signal strength is selected from the first signal strengths, and the pose adjusting device is controlled to adjust the antenna module to a first pose corresponding to the first target signal strength.
[0056] It can be understood that the number of the first signal strength matches the number of the poses of the antenna module, the first target signal strength is one of the first signal strengths, and the first target signal strength is selected from the first signal strengths according to a preset rule.
[0057] Each of the first signal strengths has a mapping relationship with a rotation angle of the pose adjusting device 21. After the first target signal strength is determined, the pose adjusting device 21 is rotated to a rotation angle corresponding to the first target signal strength, so that the antenna module 20 is adjusted to the first pose.
[0058] In some embodiments, the first target signal strength is selected from the first signal strengths, and the antenna module is adjusted to the first pose corresponding to the first target signal strength by controlling the pose adjusting device, including:
[0059] The maximum value of the first signal strengths is determined as the first target signal strength.
[0060] The horizontal rotation angle of the horizontal rotation assembly corresponding to the first target signal strength is obtained as the first horizontal angle.
[0061] The pitch rotation angle of the pitch rotation assembly corresponding to the first target signal strength is obtained as the first pitch angle.
[0062] The horizontal rotation assembly is controlled to rotate to the first horizontal angle, and the pitch rotation assembly is controlled to rotate to the first pitch angle.
[0063] It can be understood that the first horizontal angle is the rotation angle of the horizontal rotation assembly 210 when the signal strength of the antenna module 20 is the first target signal strength. Similarly, the first pitch angle is the rotation angle of the pitch rotation assembly 211 when the signal strength of the antenna module 20 is the first target signal strength. The first pose is the pose of the antenna module 20 when the signal strength of the antenna module 20 is the first target signal strength.
[0064] For example, as shown in Table 1 above, it is assumed that the signal strength 9a is determined as the first target signal strength. At this time, the horizontal rotation angle of the horizontal rotation assembly 210 corresponding to the signal strength 9a is 240°, and the pitch rotation angle of the pitch rotation assembly 211 corresponding to the signal strength 9a is 30°. The first horizontal angle is determined as 240°, and the first pitch angle is determined as 30°. After the horizontal rotation assembly 210 is controlled to rotate to 240° and the pitch rotation assembly 211 is controlled to rotate to 30°, the pose of the antenna module 20 is the first pose. At this time, the signal strength of the antenna module 20 can reach the first target signal strength.
[0065] In some embodiments, after the antenna module is adjusted to the first pose corresponding to the first target signal strength by controlling the pose adjusting device, the method further includes:
[0066] divide the first rotation step by a preset value to obtain a second rotation step, and obtain a first rotation angle of the pose adjusting device when the antenna module is in the first pose, and determine a second rotation range according to the first rotation angle and a preset step;
[0067] adjust the pose of the antenna module in the second rotation range according to the second rotation step, and obtain a second signal strength of the antenna module in each pose;
[0068] select a second target signal strength from each of the second signal strengths, and control the pose adjusting device to adjust the antenna module to a second pose corresponding to the second target signal strength.
[0069] It can be understood that the result of dividing the first rotation step by the preset value is the second rotation step. In addition, the current rotation angle of the pose adjusting device 21 when the antenna module 20 is in the first pose is the first rotation angle.
[0070] Taking the first rotation angle as a reference value and the preset step as a distance, the second rotation range can be determined. For example, assuming that the first rotation angle is w0 and the preset step is w1, the range of w0-w1 to w0+w1 is determined as the second rotation range.
[0071] After determining the second rotation range and the second rotation step, the pose adjusting device 21 is controlled to rotate in the second rotation range with the second rotation step as the unit rotation step to adjust the pose of the antenna module 20.
[0072] When the pose of the antenna module 20 changes, the signal strength of the antenna module 20 will also change. When the pose of the antenna module 20 is adjusted with the second rotation step as the unit rotation step of the pose adjusting device 21, the signal strength of the antenna module 20 in each pose recorded is the second signal strength.
[0073] Each second signal strength has a mapping relationship with the rotation angle of the pose adjusting device 21. After selecting the maximum value from each second signal strength as the second target signal strength, the pose adjusting device 21 is rotated to the rotation angle corresponding to the second target signal strength, so that the antenna module 20 is adjusted to the second pose.
[0074] It can be understood that in the process of adjusting the pose of the antenna module 20 in the first rotation range according to the first rotation step to determine the first target signal strength, and controlling the pose adjusting device 21 to adjust the antenna module 20 to the first pose corresponding to the first target signal strength, the coarse adjustment of the pose of the antenna module 20 is completed, and the antenna module 20 can quickly obtain a good signal strength.
[0075] In the process of adjusting the position of the antenna module 20 in the second rotation range according to the second rotation step to determine the second target signal strength, and controlling the position adjusting device 21 to adjust the antenna module 20 to the second position corresponding to the second target signal strength, fine adjustment of the position of the antenna module 20 is completed, so that the antenna module can obtain better signal strength.
[0076] In some embodiments, the ratio of the first rotation step to a preset value is calculated as a second rotation step, a first rotation angle of the position adjusting device when the antenna module is in the first position is obtained, and a second rotation range is determined according to the first rotation angle and a preset step, including:
[0077] The ratio of the first horizontal step to a preset value is taken as a second horizontal step, and the ratio of the first pitch step to the preset value is taken as a second pitch step;
[0078] The first horizontal angle is taken as a reference value, and a second horizontal rotation range is determined with the first horizontal step as a radius;
[0079] The first pitch angle is taken as a reference value, and a second pitch rotation range is determined with the first pitch step as a radius.
[0080] It can be understood that the ratio of the first horizontal step to a preset value is obtained as a second horizontal step; assuming that the first horizontal angle is a, and the first horizontal step is a1, the second horizontal rotation range is a-a1 to a+a1.
[0081] Similarly, the ratio of the first pitch step to a preset value is obtained as a second pitch step; assuming that the first pitch angle is b, and the first pitch step is b1, the second pitch rotation range is b-b1 to b+b1.
[0082] In some embodiments, the position of the antenna module is adjusted in the second rotation range according to the second rotation step, and the second signal strength of the antenna module at each position is obtained, including:
[0083] The horizontal rotation component is controlled to make the antenna module horizontally rotate in the second horizontal rotation range according to the second horizontal step, and the pitch rotation component is controlled to make the antenna module pitch rotate in the second pitch rotation range according to the second pitch step, so as to adjust the position of the antenna module;
[0084] The signal strength of the antenna module at each position is recorded as a second signal strength.
[0085] It can be understood that after the second horizontal rotation range and the second horizontal step length are determined, the horizontal rotation assembly 210 can be controlled to drive the antenna module 20 to perform horizontal rotation within the second horizontal rotation range with the second horizontal step length as the rotation step length. Correspondingly, after the second elevation rotation range and the second elevation step length are determined, the elevation rotation assembly 211 can be controlled to drive the antenna module 20 to perform elevation rotation within the second elevation rotation range with the second elevation step length as the rotation step length. In this process, the signal strength of the antenna module 20 at each pose is recorded as a second signal strength, and the number of second signal strengths matches the number of poses of the antenna module 20.
[0086] In some embodiments, the preset numerical value is a value greater than 1, the calculated second horizontal step length is smaller than the first horizontal step length, and the calculated second elevation step length is smaller than the first elevation step length. In this case, the pose adjustment device 21 can use a smaller step length as the unit rotation step length to fine-tune the pose of the antenna module 20, so that the antenna module 20 can obtain a better signal strength.
[0087] For example, assuming that the first horizontal angle is 240° and the first horizontal step length is 120°, the second horizontal rotation range is 180° to 300°. Assuming that the first elevation angle is 30° and the first elevation step length is 10°, the second elevation rotation range is 20° to 40°. Assuming that the preset numerical value is 2, the second horizontal step length is 30°, and the second elevation step length is 5°. In the second horizontal rotation range and the second elevation rotation range, the rotation combination of the horizontal rotation assembly 210 and the elevation rotation assembly 211 and the number of second signal strengths are shown in Table 2.
[0088] Table 2,
[0089]
[0090]
[0091] In some embodiments, the second target signal strength is selected from each of the second signal strengths, and the pose adjustment device is controlled to adjust the antenna module to a second pose corresponding to the second target signal strength, including:
[0092] determining the maximum value in each of the second signal strengths as the second target signal strength;
[0093] obtaining the horizontal rotation angle corresponding to the horizontal rotation assembly under the second target signal strength as the second horizontal angle;
[0094] obtaining the elevation rotation angle corresponding to the elevation rotation assembly under the second target signal strength as the second elevation angle;
[0095] controlling the horizontal rotating assembly to rotate to the second horizontal angle and controlling the pitching rotating assembly to rotate to the second pitching angle.
[0096] It can be understood that the second horizontal angle is the rotating angle of the horizontal rotating assembly 210 when the signal strength of the antenna module 20 is the second target signal strength; similarly, the second pitching angle is the rotating angle of the pitching rotating assembly 211 when the signal strength of the antenna module 20 is the second target signal strength. And the second pose is the pose of the antenna module 20 when the signal strength of the antenna module 20 is the second target signal strength.
[0097] For example, as shown in Table 2 above, it is assumed that the “signal strength 22b” is determined to be the second target signal strength. Because the horizontal rotating angle of the horizontal rotating assembly 210 corresponding to the “signal strength 22b” is 210°, and the pitching rotating angle of the pitching rotating assembly 211 corresponding to the “signal strength 22b” is 40°. Then the second horizontal angle is determined to be 210°, and the second pitching angle is determined to be 40°. At this time, after controlling the horizontal rotating assembly 210 to rotate to 210° and controlling the pitching rotating assembly 211 to rotate to 40°, the pose of the antenna module 20 is the second pose, and at this time, the signal strength of the antenna module 20 can reach the second target signal strength.
[0098] In some embodiments, the antenna module comprises a parabolic reflector and an antenna array, the antenna array being a feed source of the parabolic reflector.
[0099] Please refer to Figure 3 , Figure 3 A structural schematic diagram of an antenna provided by an embodiment of the present application.
[0100] As Figure 3 shown, the antenna module 20 comprises a parabolic reflector 201 and an antenna array 202, and the antenna array 202 is a feed source of the parabolic reflector 201.
[0101] Wherein, when the antenna module 20 transmits a signal, the antenna array 202 radiates the to-be-transmitted signal to the direction of the parabolic reflector 201, and the to-be-transmitted signal is reflected by the parabolic reflector 201 and transmitted to the base station along the normal direction of the parabolic reflector 201. Correspondingly, when the antenna module 20 receives a to-be-received signal from the base station, the to-be-received signal is reflected by the parabolic reflector 201 and converges into the antenna array 202.
[0102] Before the direction pattern of the antenna module is acquired, the method further comprises:
[0103] An aperture of the parabolic reflecting surface is obtained, and a product of a preset focal diameter ratio and the aperture is calculated as an initial focal length;
[0104] An initial relative position of the parabolic reflecting surface on an axis and at a distance of the initial focal length from the parabolic reflecting surface is obtained, and a plurality of positions at distances from the initial relative position within a preset distance range are obtained as preselected relative positions;
[0105] Gain values of the antenna array when arranged at the respective preselected relative positions are calculated;
[0106] A position of the antenna array at which the gain value is maximum is selected as a target relative position from the respective preselected relative positions, and the antenna array and the parabolic reflecting surface are fixedly connected according to the target relative position.
[0107] In some embodiments, the preset focal diameter ratio can be set to 1.02, and assuming that the aperture of the parabolic reflecting surface 201 is 80 mm, the calculated initial focal length is 81.6 mm. In addition, the preset focal diameter ratio can also be selected as other values according to the situation, which is not limited herein.
[0108] In some embodiments, the preset distance range can be a range determined by a product of the initial focal length and a preset percentage, and in addition, the preset distance range can also be determined in other manners, which is not limited herein.
[0109] In some embodiments, when the preselected relative positions are selected within the preset distance range, a plurality of points on the axis of the parabolic reflecting surface 201 at distances from the initial relative position within the preset distance range can be selected as the preselected relative positions. In addition, the preselected relative positions are not limited to being selected on the axis of the parabolic reflecting surface 201, and a plurality of points can also be selected as the preselected relative positions with the initial relative position as a spherical center and the preset distance range as a radius, which is not limited herein.
[0110] In some embodiments, after the preset distance range is determined, the parabolic reflecting surface 201 and the antenna array 202 can be simulated and designed to measure the gain values of the antenna array 202 at the respective relative positions. In addition, the position of the antenna array 202 can also be adjusted by using a preset auxiliary mechanical device, and the gain values of the antenna array 202 at the respective relative positions can be measured by using an antenna gain measuring instrument. Of course, the gain of the antenna array 202 at different positions can also be calculated in other manners, which is not limited herein.
[0111] After the gain values of the antenna array 202 at the respective preselected relative positions are calculated, the preselected relative position corresponding to the maximum gain value of the antenna array 202 can be selected as the target relative position.
[0112] In the prior art, the antenna array 202 is used as a feed source of the parabolic reflector 201, and phase deviation may occur, thereby causing the main lobe of the antenna module 20 to split. It can be understood that the relative position of the target is the relative position of the axis of the parabolic reflector 201. According to the technical solution provided in the embodiment, the antenna array 202 is fixedly connected with the parabolic reflector 201 according to the relative position of the target, so that the influence of the phase deviation of the antenna array 202 can be eliminated as much as possible, and the problem of the main lobe splitting of the antenna module 20 can be avoided.
[0113] In some embodiments, the antenna array includes a radio frequency transceiver chip and a plurality of array-arranged and in-phase millimeter wave antennas in electrical communication with the radio frequency transceiver chip;
[0114] The control terminal is in electrical communication with the radio frequency transceiver chip through a medium frequency coaxial cable;
[0115] After the pose adjustment device is controlled to adjust the antenna module to a first pose corresponding to the first target signal strength, the method further includes:
[0116] When the antenna array is working, the radio frequency transceiver chip is controlled to down-convert the working frequency band of the millimeter wave antenna to a preset frequency band.
[0117] It can be understood that the antenna array 202 of the antenna module 20 includes a plurality of array-arranged and in-phase millimeter wave antennas. Compared with a traditional parabolic antenna with a single antenna feed source, the use of the antenna array 202 in the embodiment can increase the transmission power, and under the same antenna gain, a higher EIRP can be achieved, and the transmission capability is stronger.

However, the electrical communication between the control terminal 1 and the antenna 2 through the medium frequency coaxial cable may have a negative impact on the performance of the millimeter wave antenna.
[0119] In the embodiment, the radio frequency transceiver chip is in electrical communication with the millimeter wave antenna, and the control terminal 1 is in electrical communication with the radio frequency transceiver chip through a medium frequency coaxial cable. When the antenna array 202 is working, the radio frequency transceiver chip is used to down-convert the working frequency band of the millimeter wave antenna to a preset frequency band, which can solve the problem that the performance of the millimeter wave antenna is affected when the control terminal 1 is in electrical communication with the antenna 2 through the medium frequency coaxial cable.
[0120] In some embodiments, the preset frequency band can be a frequency band below 15 GHz, below 13 GHz or below 9 GHz, and can also be adjusted to other frequency bands as needed without limitation.
