Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0062] In this exemplary embodiment, a slot antenna testing device is first provided. Figures 1 to 9 As shown in FIG, the device includes a positioning seat 100 , a clamping assembly 200 , two pressing members 300 and a test probe 400 .

[0063] The positioning seat 100 extends along the first direction and is provided with a positioning groove 110 for accommodating the slot antenna 500 to be tested. The positioning groove 110 includes a first groove 111, a second groove 112 and a third groove 113 which are arranged through the first direction. The first groove 111 is provided on a side surface of the positioning seat 100 along the second direction. The second groove 112 is provided at the bottom of the first groove 111, and the third groove 113 is provided at the bottom of the second groove 112.

[0064] The clamping assembly 200 includes a pressure rod 210, two baffles 220, and a first connecting rod 230 and a second connecting rod 240 respectively connected to the two baffles 220. The two baffles 220 are accommodated in the third groove 113 and are located on both sides of the slot antenna 500 to be tested along the third direction. The pressure rod 210, the first connecting rod 230 and the second connecting rod 240 are all adjustably arranged on the positioning seat 100 along the third direction, and the pressure rod 210 is abutted against one of the baffles 220.

[0065] Two pressing members 300 are installed in the first groove 111 and are located on both sides of the slot antenna 500 to be tested along the third direction. The pressing members 300 are used to press the side wings 520 of the slot antenna 500 to be tested along the second direction.

[0066] The test probe 400 is located along the second direction at a side of the positioning base 100 where the positioning groove 110 is formed, and is movably arranged along the first direction for testing the slot antenna 500 to be tested.

[0067] Among them, the first direction, the second direction, and the third direction are perpendicular to each other; the first direction is parallel to the length direction of the slot antenna 500 to be tested, such as Figure 1 The direction indicated by the arrows ab; the second direction is as Figure 1 The direction indicated by the arrow cd; the third direction is as follows Figure 1 The direction indicated by the arrow ef.

[0068] It should be explained that the slot antenna 500 to be tested includes an antenna body 510, a wing 520, and a flange 530; wherein the antenna body 510 is in the shape of a long strip and has a cavity running through its length direction, combined with Figure 1 and Figure 2 , one side surface of the antenna body 510 along the second direction is a slot surface 511, that is, the surface has a plurality of slots 5111 spaced apart along the length direction of the antenna body 510, and the slot 5111 spacing, slot 5111 inclination angle and slot 5111 depth of the slot 5111 are the data to be tested; combined with Figure 1 and Figure 2 The antenna body 510 is provided with side wings 520 on both sides along the third direction, and a flange 530 is provided at one end of the antenna body 510 along the first direction. The flange 530 is used for externally connecting an RF connector during testing to put the slot antenna 500 to be tested into operation; wherein, the length direction of the antenna body 510 is the length direction of the slot antenna 500 to be tested, which is parallel to the first direction.

[0069] In the embodiment of the present disclosure, the positioning groove 110 provided on the positioning seat 100 is used to accommodate the slot antenna 500 to be tested, and the slot surface 511 of the slot antenna 500 to be tested can be oriented toward the outside of the positioning groove 110. The clamping assembly 200 cooperates with the positioning seat 100 to achieve clamping and positioning of the slot antenna 500 to be tested in the third direction. The two pressing members 300 cooperate with the positioning seat 100 to achieve compression and positioning of the slot antenna 500 to be tested in the second direction. At the same time, with the help of the pressure rod 200 of the clamping assembly 200, the slot antenna 500 to be tested can be clamped and positioned. The pressure applied by 10 on both sides of the slot antenna 500 to be tested and the pressure applied by the pressing member 300 on the side wings 520 of the slot antenna 500 to be tested can also ensure that the slot antenna 500 to be tested is positioned in the first direction. By moving the test probe 400 along the first direction, the slot surface 5111 of the positioned and clamped slot antenna 500 to be tested can be tested, thereby realizing batch testing of the slot 5111 spacing, slot 5111 inclination angle and slot 5111 depth of multiple slots 5111 on the slot surface 511 of the slot antenna 500 to be tested.

[0070] Below, each step of the above method in this exemplary embodiment will be described in more detail.

[0071] In one embodiment, reference Figures 4 to 6 As shown in , the pressing member 300 includes a main body portion 310 extending along the first direction and a first pressing portion 320 and a second pressing portion 330, wherein the first pressing portion 320 and the second pressing portion 330 are respectively connected to two sides of the main body portion 310 along the third direction;

[0072] The main body 310 is detachably connected to the bottom of the second groove 112 of the positioning seat 100 , the first pressing portion 320 is used to press the side wing 520 of the slot antenna 500 to be tested, and the second pressing portion 330 presses against the bottom of the first groove 111 .

[0073] It should be noted that the first pressing portions 320 of the two pressing members 300 are respectively used to press the two side wings 520 of the slot antenna 500 to be tested in the second direction, so as to achieve the compression and fixation of the two side wings 520 of the slot antenna 500 to be tested. The structural arrangement of the above-mentioned pressing members 300 cooperates with the first groove 111 and the second groove 112 to achieve the stable installation of the pressing members 300 in the first groove 111 while also compressing the side wings 520 of the slot antenna 500 to be tested. In addition, the main body 310 is designed to be detachably connected to the bottom of the second groove 112 of the positioning seat 100, so that the pressing members 300 can be installed on the positioning seat 100 during testing and removed from the positioning seat 100 after the test.

[0074] Optionally, a fastener 311 is provided through the main body 310, and a first threaded hole 1121 is defined at the bottom of the second groove 112. The fastener 311 is threadedly connected to the first threaded hole 1121. The main body 310 has a first mounting hole 312 extending along the second direction for the fastener 311 to pass through. The fastener 311 can be a screw, etc. The fastener 311 is threadedly connected to the bottom of the second groove 112, facilitating assembly and disassembly, as well as facilitating temporary securing or tightening of the compression member 300 by loosening or tightening the screw.

[0075] It should be noted that the size of the clamping member 300 in the first direction is the same as the length of the slot antenna 500 to be tested. The clamping member 300 not only plays the role of compressing the slot antenna 500 to be tested, but also is used to simulate the surrounding test environment of the slot antenna 500 to be tested to ensure the accuracy of the test results of the slot antenna 500 to be tested.

[0076] In one embodiment, reference Figure 5 and Figure 7 As shown in the figure, one end of the first connecting rod 230 and one end of the second connecting rod 240 are respectively threadedly connected to the two baffles 220 in a one-to-one correspondence, and the other end of the first connecting rod 230 and the other end of the second connecting rod 240 respectively pass through the positioning seat 100 and are exposed from the positioning seat 100.

[0077] By passing the first connecting rod 230 and the second connecting rod 240 through the positioning base 100 and threadedly connected to the two baffles 220 in a one-to-one correspondence, the first connecting rod 230 and the second connecting rod 240 can be installed with the two baffles 220 respectively during testing. It is also convenient to disassemble the first connecting rod 230 and the second connecting rod 240 from the two baffles 220 respectively after the test is completed. This prevents the baffles 220 from falling to the other side wall of the third groove 113 under the action of gravity after the slot antenna 500 to be tested is withdrawn from the third groove 113. The threaded connection method also ensures a stable connection between the first connecting rod 230 and one baffle 220, and between the second connecting rod 240 and the other baffle 220. During the test process, the first connecting rod 230 and the second connecting rod 240 can stably pull the corresponding baffle 220, adjust the position of the baffle 220, and make the baffle 220 closely contact the inner wall of the third groove 113.

[0078] It should be noted that the reference Figure 7As shown, the axial direction of the first connecting rod 230 and the axial direction of the second connecting rod 240 are set parallel to the direction of gravity, and in the direction of gravity, the first connecting rod 230 is located on the upper side of the positioning seat 100, and the second connecting rod 240 is located on the lower side of the positioning seat 100. The first connecting rod 230 can be used to prevent the baffle 220 connected to the first connecting rod 230 from falling to the side where the second connecting rod 240 is located under the action of gravity, so that the slot antenna 500 to be tested can be smoothly inserted into the positioning groove 110 of the positioning seat 100.

[0079] It should also be noted that the reference Figure 7 As shown, the length of the first connecting rod 230 is greater than the length of the second connecting rod 240. Since the baffle 220 connected to the second connecting rod 240 can remain on the lower side of the positioning seat 100 under the action of gravity, the baffle 220 connected to the first connecting rod 230 will fall to the side where the second connecting rod 240 is located under the action of gravity, that is, during the test, the baffle 220 connected to the first connecting rod 230 has a larger range of movement along the direction of gravity. Therefore, the above-mentioned length of the first connecting rod 230 is set to be greater than the length of the second connecting rod 240, so that in the direction of gravity, the first connecting rod 230 can fully adjust the position of the baffle 220 connected to the first connecting rod 230.

[0080] Specifically, a first connecting hole 130 and a second connecting hole 140 are provided on the positioning seat 100, the first connecting hole 130 is for the first connecting rod 230 to pass through, and the second connecting hole 140 is for the second connecting rod 240 to pass through; wherein, the axial directions of the first connecting hole 130 and the second connecting hole 140 are parallel to the third direction, and one end of the first connecting hole 130 is connected to the third groove 113, and the other end of the first connecting hole 130 is connected to a side surface of the positioning seat 100 along the third direction, one end of the second connecting hole 140 is connected to the third groove 113, and the other end of the second connecting hole 140 is connected to the other side surface of the positioning seat 100 along the third direction.

[0081] Specifically, one end of the first connecting rod 230 and one end of the second connecting rod 240 are provided with external threads, wherein both baffles 220 are provided with second threaded holes 221, one end of the first connecting rod 230 is threadedly connected to the second threaded hole 221 of one of the baffles 220, and one end of the second connecting rod 240 is threadedly connected to the second threaded hole 221 of the other baffle 220.

[0082] In one embodiment, reference Figure 5 and Figure 8As shown in , the pressure rod 210 is threadedly connected to the positioning seat 100, and one end of the pressure rod 210 extends into the third groove 113 and presses against one of the baffles 220, while the other end of the pressure rod 210 is exposed outside the positioning seat 100. A third threaded hole 150 is defined on the positioning seat 100, one end of which communicates with the third groove 113, and the other end of which communicates with a side surface of the positioning seat 100 along the third direction. The outer surface of the pressure rod 210 is provided with an external thread.

[0083] In the above setting, the pressure rod 210 can be moved and adjusted relative to the positioning seat 100 along the third direction by screwing the pressure rod 210. When the pressure rod 210 is moved along the third direction toward the third groove 113 by screwing the pressure rod 210, the pressure rod 210 can be used to press one of the baffles 220 so that the two baffles 220 clamp the slot antenna 500 to be tested along the third direction; when the pressure rod 210 is moved along the third direction away from the third groove 113 by screwing the pressure rod 210, the pressure rod 210 can be disengaged from the baffle 220 and the pressure rod 210 can be removed from the positioning seat 100.

[0084] Optionally, an operating portion 211 is provided at one end of the pressing rod 210 exposed from the positioning seat 100 , so that an operator can hold the operating portion 211 to rotate the pressing rod 210 .

[0085] Optionally, the baffle 220 is made of a non-metallic material with a small surface friction coefficient to reduce resistance when the slot antenna 500 to be tested is inserted into the third groove 113 or withdrawn from the third groove 113 .

[0086] In one embodiment, a dimension of the second groove 112 in the third direction is smaller than a dimension of the first groove 111 in the third direction, and a dimension of the second groove 112 in the third direction is larger than a dimension of the third groove 113 in the third direction.

[0087] By limiting the dimensions of the first groove 111, the second groove 112, and the third groove 113 in the third direction, the positioning groove 110 composed of the first groove 111, the second groove 112, and the third groove 113 is made to be a stepped groove, so that the third groove 113 of the positioning groove 110 is adapted to the baffle 220 and part of the slot antenna 500 to be tested, the second groove 112 of the positioning groove 110 is adapted to the side wing 520 of the slot antenna 500 to be tested, and the first groove 111 of the positioning groove 110 is adapted to the pressing piece 300 and part of the slot antenna 500 to be tested.

[0088] It should be noted that the size of the third groove 113 of the positioning groove 110 in the second direction is adapted to the size of the baffle 220 in the second direction, and when the slot antenna 500 to be tested is positioned in the positioning groove 110, there is a gap between the side surface of the slot antenna 500 to be tested that is away from the slot surface 511 along the second direction and the bottom of the third groove 113.

[0089] It should be noted that the size of the second groove 112 of the positioning groove 110 in the second direction is adapted to the size of the side wings 520 of the slot antenna 500 to be tested in the second direction, and when the slot antenna 500 to be tested is positioned in the positioning groove 110, along the second direction, the side wings 520 of the slot antenna 500 to be tested are clamped between the baffle 220 and the pressing member 300.

[0090] It should be noted that the size of the first groove 111 of the positioning groove 110 in the second direction is adapted to the size of the clamping member in the second direction, and when the slot antenna 500 to be tested is positioned in the positioning groove 110, the slot surface 511 of the slot antenna 500 to be tested is flush with the surface of the positioning seat 100, and the clamping member is accommodated in the first groove 111.

[0091] In one embodiment, reference Figure 3 and Figure 9 As shown in , a relief groove 120 is formed on the other side surface of the positioning base 100 along the second direction.
