Technical Field

[0001] This utility model relates to the field of transmitting antenna testing technology, and in particular to a transmitting antenna calibration device and system. Background Technology

[0002] Transmitting antennas are an indispensable component of wireless communication systems. Their main function is to effectively convert received radio frequency signals into electromagnetic waves and radiate them into space to achieve long-distance information transmission. The performance of transmitting antennas directly affects the coverage, signal quality, data transmission rate, and overall efficiency of the communication system. Therefore, calibrating transmitting antennas is a key step to ensure that antenna performance meets design requirements.

[0003] However, current solutions either have a large calibration device that weighs over 100 kilograms, making it difficult to carry and unable to meet the calibration needs of different work sites, or the calibration device can only work in a fixed laboratory and cannot be carried to the work site.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a transmitting antenna calibration device provided by this utility model.

[0047] This transmitting antenna calibration device is used in a transmitting antenna calibration system. The transmitting antenna calibration system also includes a signal output module connected to the transmitting antenna under test. The transmitting antenna calibration device includes a control module 1, a first support component 2, a probe clamping component 3, a transmission component, and a support base 4.

[0048] The probe clamping component 3 is detachably connected to the first support component 2 in the height direction of the first support component 2, and the first support component 2 is detachably connected to the support base 4, and the first support component 2 and the support base 4 are perpendicular to each other when connected.

[0049] The probe clamping component 3 is used to clamp the field strength probe; the field strength probe is also connected to the control module 1 to receive the electromagnetic wave signal propagated by the transmitting antenna under test, and generate a corresponding field strength signal to send to the control module 1.

[0050] The transmission component is detachably connected to the support base 4, and when connected, the transmission component contacts the bottom of the first support component 2 under the support of the support base 4;

[0051] The control module 1 is connected to the transmission assembly and is used to control the transmission assembly to reciprocate along the length of the support base 4 so as to drive the first support component 2 and the field strength probe to move synchronously.

[0052] In this embodiment, considering that current antenna calibration devices are either bulky and inconvenient to carry, or can only be used in fixed laboratories and cannot be taken to the field, this application provides a portable antenna calibration device that can be flexibly carried to various work sites according to actual needs.

[0053] First, it should be noted that the transmitting antenna under test here can be a horn antenna, a directional antenna, an omnidirectional antenna, or a parabolic antenna, etc., without any particular limitation; please refer to... Figure 2 , Figure 2 This is a schematic diagram of a transmitting antenna calibration system provided by this utility model. The signal output module may include a signal generator 71, a power amplifier 72, a dual directional coupler 73, a first power meter 74, and a second power meter 75. The signal generator 71, power amplifier 72, dual directional coupler 73, and the transmitting antenna under test are connected in sequence. The dual directional coupler 73 is also connected to the first power meter 74 and the second power meter 75. Since the working site has a semi-anechoic chamber, the transmitting antenna under test and the transmitting antenna calibration device are both set in the semi-anechoic chamber. Unit 71 is used to output a standard continuous wave signal; power amplifier 72 is used to amplify the power of the standard continuous wave signal; dual directional coupler 73 is used to convert the amplified standard continuous wave signal into a traveling wave signal, which is transmitted to the transmitting antenna under test through the connecting cable between the dual directional coupler 73 and the transmitting antenna under test, and the dual directional coupler 73 is also used to receive the reverse signal reflected back by the transmitting antenna under test; first power meter 74 is used to determine the power of the traveling wave signal in order to determine the actual transmission power in the future; second power meter 75 is used to determine the power of the reverse signal.

[0054] The transmitting antenna under test is used to convert the received traveling wave signal into an electromagnetic wave signal that can propagate in the air. Specifically, this electromagnetic wave signal can be a spherical wave signal. The field strength probe can detect this electromagnetic wave signal and generate a corresponding field strength signal, which is then sent to control module 1 (specifically, to the receiver in control module 1). Figure 2 For clarity, the signal generator 71, power amplifier 72, dual directional coupler 73, and the transmitting antenna under test are essentially connected sequentially via cables. Figure 2 The cable connection is represented by a solid line; the electromagnetic wave propagation is achieved through air propagation by the field strength probe in the antenna under test and the antenna calibration device. Figure 2 The lieutenant general represents this kind of dissemination with a dashed line.

[0055] More specifically, the probe clamping component 3 can be detachably connected along the height direction of the first support component 2, thereby allowing the field strength probe to be flexibly positioned at different heights from the ground on the first support component 2 according to actual needs, thus changing the height of the field strength probe from the ground. Please refer to... Figure 3 , Figure 3This is a schematic diagram of another transmitting antenna calibration device provided by this utility model. The probe clamping component 3 may include a gripper 31 and a locking structure 32. The gripper 31 is used to clamp the field strength probe. When not locked, the locking structure 32 can slide on the first support component 2 to adjust the height of the gripper 31 (it can also be detached from the first support component 2) to achieve height adjustment of the field strength probe. When locked, it can fix the field strength probe. The specific mechanical structure of the locking structure 32 is not particularly limited here. Various mechanical structures that can achieve the above functions can be used as the locking structure 32, and can be flexibly set according to the actual situation. In addition, it can be understood that... Figure 1 This is only a simplified schematic diagram and does not show the locking structure 32 between the probe clamping component 3 and the first support component 2. Instead, it emphasizes that the probe clamping component 3 can be connected to the first support component 2.

[0056] The first support component 2 can be connected to the support base 4 before testing begins, or detached from the support base 4 after testing for easy storage, thus achieving a detachable connection; and during connection, such as Figure 1 As shown, the support base 4 is arranged along the length direction, and the first support component 2 is arranged along the height direction.

[0057] The transmission component can be connected to the support base 4 before the test starts according to the application requirements, so as to achieve close contact and connection with the bottom of the first support component 2 during the connection, or to be separated from the support base 4 after the test for easy storage, thereby realizing the detachable connection between the transmission component and the support base 4; and since the transmission component is in close contact and connected with the first support component 2, the first support component 2 will move synchronously with the transmission component when the transmission component moves, that is, the synchronous movement of the field strength probe is realized.

[0058] It should also be noted that before the actual calibration test begins, the transmitting antenna under test needs to be placed in a semi-anechoic chamber, and the installation and connection of the calibration device must be completed in the semi-anechoic chamber. This means completing the connection between the first support component 2 and the support base 4, the transmission component and the support base 4, and the transmission component and the control module 1. When fixing the support base 4, it is necessary to ensure that the length direction of the support base 4 is consistent with the main axis direction of the transmitting antenna under test. Subsequently, the field strength probe is aligned with the transmitting antenna under test; specifically, the center of the field strength probe should be aligned with the center of the transmitting antenna under test, and locked using the locking structure 32 of the probe clamping component to ensure reliable fixation of the field strength probe. The distance between the field strength probe and the transmitting antenna under test is adjusted to a preset distance, which can be 1 meter. Preferably, the calibration device may also include a laser... An optical rangefinder is used to ensure the correct alignment of the field strength probe with the center of the transmitting antenna under test and to ensure that the two are at a preset distance. After the above settings are completed, calibration testing can begin. That is, according to the actual test requirements, the transmission component is controlled to move along the length of the support base 4 to various positions to measure the field strength signal at each position. During this process, the transmitting antenna under test remains stationary. For the receiver in the control module 1, after receiving the current field strength signal, it can analyze parameters such as antenna coefficients. There is no particular limitation on what kind of analysis is performed using the field strength signal. After the field strength signal at one position is received, the position controller in the control module 1 will drive the transmission component to move to the next position via the motor, ultimately realizing the measurement of the field strength signal at each position.

[0059] In summary, this application provides a transmitting antenna calibration device. The detachable connection between the components of the device makes the entire device easy to carry to various work sites as needed for accurate calibration testing of the transmitting antenna under test. It is highly portable, has high testing efficiency, and is beneficial for practical applications.

[0060] Based on the above embodiments:

[0061] In some embodiments, a ruler is also included;

[0062] A scale is set on the side of the support base 4 to indicate the current movement position of the first support component 2.

[0063] In this embodiment, taking the support base 4 as an example, which includes a support rail and a second support component 45, and the device also includes an isolation plate 6, preferably, the scale can be set on the side of the support rail away from the isolation plate 6, so that the scale will not be blocked by the isolation plate 6 and thus affect the indication of the movement position.

[0064] As can be seen, the setting of the scale can more intuitively indicate the movement position of the first support component 2, so that technicians can know it; more specifically, setting the scale is conducive to better testing of the 3dB beamwidth item, that is, when the control module 1 drives the field strength probe to move to the 3dB beamwidth field strength signal position by controlling the movement of the transmission component, the corresponding left and right positions along the length direction are the coverage range of the transmitting antenna under test under the 3dB beamwidth.

[0065] In some embodiments, the support base 4 includes a second support member 45 and a support rail;

[0066] The support rail is detachably connected to the first support component 2, and the support rail is set along the length direction, while the first support component 2 is set along the height direction. The support rail is used to provide the first support component 2 with a sliding rail that moves synchronously with the transmission component.

[0067] The second support component 45 is fixedly connected to the support rail and is arranged along the width direction. The transmission component is detachably connected to the second support component 45. The second support component 45 is used to provide support for the transmission component so that the transmission component contacts the bottom of the first support component 2.

[0068] In this embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of another transmitting antenna calibration device provided by this utility model, and Figure 4 The diagram illustrates the setup of each device from a top-down view. The support rails here can include a first support rail 41 and a second support rail 42. When the field strength probe needs to move a long distance, the first support rail 41 and the second support rail 42 will also be longer. For ease of storage and portability, they can be arranged as follows: Figure 4 As shown, Figure 4 Any dotted line in the diagram indicates that the left and right sections of the support rail can be separated at this location, forming a total of four sections for easy storage. During installation, one of the left and right support rail sections has an internal thread, while the other has an external thread. The complete support rail is then obtained by tightening the threads. More specifically, the support rail can be cylindrical. Taking the first dotted line from left to right as an example, the left section of the support rail corresponding to this dotted line can also be provided with a first stable base 43 for securing the support rail, and the right section of the support rail can also be provided with a second stable base 44 for securing the support rail. This ensures that the support rail can be placed stably on the ground or tabletop, and also better ensures that the support rail provides stable support for the first support component 2. The settings at the other dotted lines are similar and will not be elaborated here.

[0069] It should also be noted that, such as Figure 4As shown, taking a transmission assembly including a synchronous belt 53 as an example, the second support member 45 is disposed between the first support rail 41 and the second support rail 42. The synchronous belt 53 is specifically disposed between the first support rail 41 and the second support rail 42, and the second support member 45 is disposed along the width direction, that is, one end of the second support member 45 is fixedly connected to the second support rail 42 and extends towards the direction of the first support rail 41. Specifically, there are no particular limitations on the specific mechanical structure and shape of the second support member 45; any component that can provide support for the synchronous belt 53 so that the synchronous belt 53 is in close contact with the bottom of the first support member 2 is acceptable. It can be flexibly configured according to the actual situation. For example, please refer to... Figure 3 , Figure 3 The second support component 45 adopts a T-shaped structure, with its first end fixedly connected to the support rail, its second end connected to the stable base, and its third end used to contact the synchronous belt 53 to provide support for the synchronous belt 53.

[0070] Furthermore, when the transmitting antenna calibration device includes a scale, the scale may be specifically located on the outer side of the first support rail 41 opposite to the second support rail 42.

[0071] Understandably, there is no specific limit to the length of the support track here. It depends on the specific travel distance required by the field strength probe. The travel distance here can be 300cm.

[0072] In some embodiments, the first support member 2 includes a support rod 21 and a slidable base 22;

[0073] The sliding base 22 is provided with a positioning hole 221, and the support rod 21 is detachably connected to the sliding base 22 through the positioning hole 221; the sliding base 22 is detachably slidably connected to the support rail.

[0074] The sliding base 22 is used to contact the transmission component during sliding connection, and thus move synchronously with the transmission component;

[0075] The probe clamping component 3 is detachably connected to the support rod 21 in the height direction of the support rod 21.

[0076] Specifically, such as Figure 4 As shown, the sliding base 22 has a positioning hole 221, into which the support rod 21 can be inserted for reliable connection with the sliding base 22. Alternatively, an internal thread can be machined in the positioning hole 221, and an external thread can be machined on the bottom of the support rod 21, allowing for tightening to achieve the connection. Furthermore, as... Figure 1As shown, when the bottom of the support column includes a trapezoidal base, the slidable base 22 may include at least two screw holes, preferably four screw holes, so as to fix the trapezoidal base and the slidable base 22 through the cooperation between the screw and the screw hole. No particular limitation is made here.

[0077] Please refer to Figure 5 , Figure 5 This is a schematic diagram of another transmitting antenna calibration device provided by this utility model. Specifically, the specific configuration of the bottom structure of the sliding base 22 is not particularly limited here. For example, a groove can be made on the side close to the support rail to allow it to slide against the support rail; or an arc-shaped part conforming to the shape of the support rail can be provided on the side close to the support rail. No particular limitation is made here; it can be determined according to actual needs. In principle, when the sliding base 22 is connected to the support rail, it can make close contact with the synchronous belt 53 in the transmission assembly, thereby moving synchronously with the transmission assembly.

[0078] It is understandable that there is no particular limitation on the specific adjustable height of the probe clamping component 3 on the support rod 21, but it can be determined according to the actual application requirements. For example, the adjustable height can be set at 60 cm, and combined with the height of the support base, it can be adjusted from 70 cm to 130 cm from the ground.

[0079] In some embodiments, the transmission assembly includes a driving pulley 51, a driven pulley 52, and a timing belt 53 connecting the driving pulley 51 and the driven pulley 52;

[0080] The drive wheel 51 is connected to the control module 1;

[0081] The second support component 45 supports the timing belt 53 so that the timing belt 53 contacts the bottom of the first support component 2.

[0082] Specifically, the above methods can simply and reliably achieve the function of the transmission component. Figure 4 and Figure 5 The diagrams show the configuration of the transmission components from different perspectives.

[0083] In some embodiments, the control module 1 includes a receiver, a motor, and a position controller;

[0084] The motor's output terminal is connected to the control terminal of the transmission assembly, and the motor's control terminal is connected to the position controller.

[0085] The position controller is used to control the transmission assembly to reciprocate along the length of the support base 4 via a motor;

[0086] The receiver is connected to the field strength probe to receive the field strength signal.

[0087] Specifically, in practical applications, after the receiver receives the field strength signal corresponding to the current movement position, the position controller then controls the transmission component to move through the motor, so that the field strength probe moves to the next position, until the field strength signal at each position is detected.

[0088] In some embodiments, the dielectric constant of the materials of the first support component 2, the probe clamping component 3, the transmission component and the support base 4 is not greater than 2.

[0089] In this embodiment, considering that current calibration devices use a large amount of metal materials, which reflect electromagnetic waves emitted by the antenna under test, resulting in uneven environmental field strength and high error, in this application, apart from the control module 1, the materials used for the first support component 2, probe clamping component 3, transmission component and support base 4 are all low dielectric constant materials, that is, the dielectric constant of the materials is not greater than 2; preferably, the materials of the first support component 2, probe clamping component 3, transmission component and support base 4 can be all-plastic materials, of course, they can also be nylon or fiberglass. More specifically, the screws and other components used for connection at various positions in the above embodiment are also made of all-plastic materials to ensure that a large amount of electromagnetic waves are not reflected into the anechoic chamber.

[0090] Preferably, since the motor, position controller and receiver in control module 1 are made of metal, control module 1 can be located outside the semi-anechoic chamber.

[0091] As can be seen, the above settings can effectively reduce the uncertainty introduced by the calibration device, improve the accuracy of calibration testing of the transmitting antenna under test, facilitate the timely detection and resolution of performance deviations of the transmitting antenna, optimize signal transmission quality, and avoid communication failures or interference caused by substandard performance.

[0092] In some embodiments, a partition plate 6 is also included;

[0093] The isolation plate 6 is located on the side of the support base 4 closest to the transmitting antenna under test; the height of the isolation plate 6 is not greater than the minimum height that the probe clamping component 3 can clamp on the first support component 2.

[0094] The side of the isolation plate 6 closest to the transmitting antenna under test is covered with a wave-absorbing component to absorb the dissipated electromagnetic waves.

[0095] In this embodiment, the absorbing component can effectively absorb the emitted electromagnetic waves, preventing the discrete electromagnetic waves in the environment from affecting the signal received by the field strength probe. Specifically, the absorbing component can be made of absorbing material and laid on the side of the isolation plate 6 near the transmitting antenna under test.

[0096] For details, please refer to the following: Figure 1 , Figure 1 The addition of diagonal lines to the isolation plate 6 indicates that the side of the isolation plate 6 closest to the antenna under test is covered with a wave-absorbing component. The isolation plate 6 can be convex. It should be noted that the height corresponding to the top edge of the convex structure's protrusion is not greater than the lowest height that the probe clamping component 3 can clamp on the first support component 2 (i.e., support rod 21). When the bottom of the support rod 21 includes a trapezoidal base, the height corresponding to the top edge of the convex structure's protrusion is not greater than the height corresponding to the top edge of the trapezoidal base. For example... Figure 1 As shown, the convex isolation plate 6 can be integrally formed, and according to actual needs, the isolation plate 6 can also be connected to the support base 4. For example, by using an L-shaped connector with through holes, combined with screws and screw holes respectively set at corresponding positions on the isolation plate 6 and the support base 4, a detachable connection between the isolation plate 6 and the support base 4 can be achieved.

[0097] Please refer to Figure 6 , Figure 6 This is a schematic diagram of another transmitting antenna calibration device provided by this utility model. Due to limitations in the focus of the image, the locking structure 32 between the probe clamping component 3 and the first support component 2 is not shown; instead, the emphasis is on demonstrating that the probe clamping component 3 can be connected to the first support component 2. Figure 6 As shown, the partition plate 6 here can be a convex, split structure, including a first partition plate 61 and a second partition plate 62. The first partition plate 61 and the support base 4 can be connected in the manner described in the above embodiment, which will not be repeated here. The second partition plate 62 and the sliding base 22 can be detachably connected by an L-shaped connector 63 with through holes, combined with screws and screw holes respectively set at corresponding positions on the second partition plate 62 and the sliding base 22. It can be understood that the height of the top edge of the second partition plate 62 in the height direction is not greater than the height corresponding to the top edge of the trapezoidal base.

[0098] In addition, the isolation plate 6 can also be set into a cuboid shape according to actual needs, as long as the height of the top edge of the plate in the height direction is not greater than the lowest height that the probe clamping component 3 can clamp on the first support component 2. There is no special limitation on the specific shape of the isolation plate 6.

[0099] In some embodiments, the isolation panel 6 includes at least one hinge connector so that the isolation panel 6 can be folded or unfolded via the hinge connector.

[0100] Specifically, considering that the distance that the field strength probe needs to reciprocate is relatively long, the length of the corresponding isolation plate 6 is also relatively long. To facilitate storage, the isolation plate 6 may include at least one hinge connector, which can be used to fold for storage or unfold for wave absorption.

[0101] For example, since all components except the control module 1 in this application are made of all-plastic materials, the overall weight can be reduced to no more than 20kg, which can be flexibly placed in a storage box and is convenient for a single person to carry.
