In different usage scenarios, the gain efficiency of antennas is not consistent. For example, when it is necessary to receive signals evenly in a wider area, the lower the gain efficiency, the better; when transmitting regional signals over long distances, the higher the gain efficiency, the better. Therefore, when using the antenna, the gain efficiency needs to be controlled according to different usage requirements.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] The core of the present invention is to provide an electromagnetic transmission efficiency regulator, which can control the electromagnetic transmission efficiency and adjust the antenna gain efficiency by setting an adjustment mechanism in the open waveguide transmission section to change the impedance of the electromagnetic wave, without the need for a complex structure, and is simple and convenient to operate, with low cost. Another core of the present invention is to provide a microwave transmission device and an adjustment method including the above-mentioned electromagnetic transmission efficiency regulator.

[0064] The electromagnetic transmission efficiency regulator provided by the present invention is used to change the gain efficiency of an external antenna by adjusting the electromagnetic transmission efficiency to meet different antenna usage requirements.

[0065] Please refer to Figure 1 The electromagnetic transmission efficiency regulator specifically includes an input waveguide port 1, an output waveguide port 2, and a transmission waveguide line 3, wherein the output waveguide port 2 is coaxially arranged with the input waveguide port 1 and there is a first distance space between the two. The transmission waveguide line 3 is sequentially arranged in the input waveguide port 1, the first distance space, and the output waveguide port 2 to transmit electromagnetic waves. Specifically, one end of the transmission waveguide line 3 is arranged in the input waveguide port 1, and the other end is arranged in the output waveguide port 2. Part of the transmission waveguide line 3 is arranged in the first distance space, and this part position is a non-end position on the transmission waveguide line 3, which can be the middle or any position between the middle and the end.

[0066] The input waveguide port 1 and the output waveguide port 2 completely confine the electromagnetic waves transmitted by the transmission waveguide line 3 inside them, corresponding to a closed waveguide, while the transmission of electromagnetic waves in the first distance space between the input waveguide port 1 and the output waveguide port 2 corresponds to an open waveguide. By arranging an adjustment mechanism in the first distance space, a resonant circuit is formed by the adjustment mechanism and the transmission waveguide line 3, and the impedance of the electromagnetic wave transmission is affected by the resonant circuit, so as to affect the electromagnetic transmission efficiency.

[0067] In closed waveguide transmission, the impedance to which electromagnetic waves are subjected is transmission line impedance + air impedance; in open waveguide transmission, the impedance to which electromagnetic waves are subjected is transmission line impedance + air impedance + resonant impedance. Air impedance is the ability of the air medium to block electromagnetic waves when electromagnetic waves propagate in the air medium. It is affected by the characteristics of air and the frequency of the RF signal. When both remain unchanged, the impedance difference between open waveguide transmission and closed waveguide transmission is only the resonant impedance.

[0068] The adjusting mechanism is arranged in the first distance space, and the adjusting mechanism corresponds to the part of the transmission waveguide wire 3 arranged in the first distance space. The resonant impedance of the resonant circuit is changed by moving the partial structure of the adjusting mechanism in the first distance space, so as to change the impedance received by the electromagnetic waves in the first distance space, and correspondingly change the transmission efficiency of the electromagnetic waves and the gain efficiency of the external antenna.

[0069] The movement of part of the structure of the adjustment mechanism within the first distance space can affect the impedance of the electromagnetic wave, thereby adjusting the electromagnetic transmission efficiency. The resonant circuit does not require the assistance of other active devices, the structure is simple and effective, and the cost of use is low.

[0070] In addition, the movement of a part of the structure of the adjustment mechanism within the first distance space can be achieved manually, which further simplifies the operation, improves the convenience of adjustment, and reduces costs.

[0071] The electromagnetic transmission efficiency regulator changes the gain efficiency of the antenna by changing the electromagnetic transmission efficiency; specifically, the electromagnetic transmission efficiency regulator includes an input waveguide port 1, an output waveguide port 2, and a transmission waveguide line 3, and the transmission waveguide line 3 is sequentially arranged in the input waveguide port 1 and the output waveguide port 2 to transmit electromagnetic waves; the output waveguide port 2 is coaxially arranged with the input waveguide port 1 and a first distance space is arranged between the two, and an adjustment mechanism is arranged in the first distance space, and a part of the adjustment mechanism can move in the first distance space and correspond to a part of the transmission waveguide line 3 in the first distance space, and the electromagnetic wave corresponds to the open waveguide in the first distance space; the transmission The waveguide wire 3 and the adjustment mechanism form a resonant circuit, and the impedance to which the electromagnetic wave is subjected in the first distance space is the sum of the air impedance, the transmission line impedance and the resonant impedance. The resonant impedance is changed by moving part of the structure of the adjustment mechanism in the first distance space, so as to change the impedance to which the electromagnetic wave is subjected in the first distance space, thereby changing the output efficiency of the electromagnetic wave output from the output waveguide port, thereby achieving control of the electromagnetic transmission efficiency and adjustment of the antenna gain efficiency. The electromagnetic transmission efficiency can be changed by changing the impedance of the electromagnetic wave by moving the adjustment mechanism in the first distance space, without the need for a complex structure, with simple and convenient operation and low cost of use.

[0072] On the basis of the above embodiment, the adjustment mechanism includes:

[0073] A first adjustment mechanism 4, the first adjustment mechanism 4 is electrically connected to at least a portion of the transmission waveguide 3 disposed in the first distance space;

[0074] A second adjusting mechanism 5, the second adjusting mechanism 5 can be movably arranged relative to the first adjusting mechanism 4 in a first distance space;

[0075] The support member 6, the support member 6, the first adjustment mechanism 4, the second adjustment mechanism 5, and the transmission waveguide 3 form a resonant circuit;

[0076] The support member 6 supports the input waveguide port 1 or the output waveguide port 2;

[0077] Alternatively, the support member 6 supports the input waveguide port 1 and the output waveguide port 2 .

[0078] Please refer to Figure 1 , Figure 3 , Figure 4 The first adjustment mechanism 4 and the second adjustment mechanism 5 are arranged opposite to each other, and both are made of metal. The first adjustment mechanism 4 is electrically connected to at least part of the transmission waveguide line 3. The at least part here refers to the part of the transmission waveguide line 3 arranged in the first distance space, which does not contact the tail of the input waveguide port 1 and does not contact the head of the output waveguide port 2.

[0079] There is a distance between the tail of the input waveguide port 1 and the head of the output waveguide port 2 and the first adjustment mechanism 4 , and the distances here can be the same distance or different distances without limitation.

[0080] The first adjustment mechanism 4 can transmit the electromagnetic waves transmitted by the transmission waveguide 3, and then adjust the impedance of the electromagnetic waves through the second adjustment mechanism 5 arranged opposite thereto, and then output the adjusted electromagnetic waves through the output waveguide port 2 to meet the gain efficiency of the external antenna under customer requirements.

[0081] Please refer to Figure 1 In one embodiment, the support member 6 supports the input waveguide port 1 or the output waveguide port 2, and correspondingly, at least one support member 6 is used to support the input waveguide port 1, and at least one support member 6 is used to support the output waveguide port 2. The support member 6 for supporting the input waveguide port 1 and the support member 6 for supporting the output waveguide port 2 are independently arranged components, which are convenient for installation and disassembly.

[0082] In another embodiment, the support member 6 supports the input waveguide port 1 and the output waveguide port 2, that is, the support member 6 is an integral member and one support member 6 can jointly support the input waveguide port 1 and the output waveguide port 2, thereby improving the integrity of the regulator.

[0083] The above two methods can be flexibly set in combination with specific use requirements to ensure reliable support effects and to form a resonant circuit loop in cooperation with the first adjustment mechanism 4, the second adjustment mechanism 5, and the transmission waveguide 3. In this embodiment, when used specifically, the support member 6 is a metal support member and has a portion for grounding to ensure reliable safety during operation.

[0084] The support member 6, the first adjustment mechanism 4, the second adjustment mechanism 5, and the transmission waveguide line 3 form a resonant circuit. The second adjustment mechanism 5 is movably arranged relative to the first adjustment mechanism 4 in the first distance space to change the distance between the first adjustment mechanism 4 and the second adjustment mechanism 5, so as to achieve cutting of the magnetic flux lines in the first distance space at different positions to generate current through the movement of the second adjustment mechanism 5, so as to change the impedance of the resonant circuit, and correspondingly change the impedance of the electromagnetic wave in the first distance interval, so as to correspondingly change the transmission efficiency of the electromagnetic wave, and correspondingly control the gain efficiency of the antenna, so that the gain efficiency of the antenna can be adjusted to meet customer needs.

[0085] Please refer to Fig.11 , S11 is the input reflection coefficient, reflecting the input return loss; please refer to Fig.12 , S21 is the forward transmission coefficient, reaction gain. YD - S is the distance between the first adjustment mechanism 4 and the second adjustment mechanism 5. Fig.11 and Fig.12 From the above, at the same frequency, as the distance between the first adjustment mechanism 4 and the second adjustment mechanism 5 increases, the input return loss increases and the gain decreases. Therefore, by adjusting the distance between the first adjustment mechanism 4 and the second adjustment mechanism 5, the gain can be adjusted and controlled.

[0086] Fig.13 The electromagnetic leakage efficiency is reflected in the simulation low frequency band of 2GHz-2.2GHz. The electromagnetic leakage efficiency of the electromagnetic transmission efficiency regulator is only 5%. Most electromagnetic waves can achieve good transmission performance in the device in this frequency band without affecting the transmission of electromagnetic waves.

[0087] The second adjusting mechanism 5 can move up and down relative to the first adjusting mechanism 4 within the first distance space. The movement here can be vertical movement up and down, or non-vertical movement up and down. Up and down are only relative positions. The main thing is to change the distance between the second adjusting mechanism 5 and the first adjusting mechanism 4 by moving it.

[0088] The movement of the second adjustment mechanism 5 here can be controlled manually without the need for auxiliary power components. Manual control can achieve convenient and fast adjustment, thereby reducing the cost of use.

[0089] In this embodiment, the second adjusting mechanism 5 can move up and down relative to the first adjusting mechanism 4 by sliding, or can cooperate with the second adjusting mechanism 5 through multiple slots to achieve position adjustment, which depends on actual application requirements.

[0090] On the basis of any of the above embodiments, the second adjustment mechanism 5 is slidably connected to the support member 6, and the second adjustment mechanism 5 slides along the height direction of the support member 6 to change the resonant impedance of the resonant circuit.

[0091] Please refer to Figure 1 , Figure 3 , Figure 4 The second adjustment mechanism 5 can be slidably connected to the support 6. The second adjustment mechanism 5 can slide up and down in the height direction of the support 6 to change the distance between the second adjustment mechanism 5 and the first adjustment mechanism 4, so as to adjust the resonant impedance of the resonant circuit in the first distance space, so as to adjust the impedance of the electromagnetic wave, control the electromagnetic transmission efficiency, and further control the gain efficiency of the external antenna. In the actual adjustment process, the sliding distance of the second adjustment mechanism 5 can be controlled based on the user's usage needs, so that the adjusted electromagnetic transmission efficiency can meet the customer's needs.

[0092] In the specific use process, the influence of the distance between the second adjustment mechanism 5 and the first adjustment mechanism 4 on the electromagnetic transmission efficiency and leakage efficiency can be obtained through analysis. The analysis here can be combined with theory, design software, simulation software, etc. to form a distance-electromagnetic transmission efficiency-leakage efficiency corresponding relationship diagram or relationship type, so as to provide theoretical support for users to quickly and effectively adjust the electromagnetic transmission efficiency. If the adjustment mechanism has the problem of inaccurate adjustment after multiple uses, the distance-electromagnetic transmission efficiency-leakage efficiency relationship in actual application can be analyzed again through design software and simulation software to obtain a new corresponding relationship diagram or relationship, etc., and the new relationship diagram or relationship can be used to provide a theoretical reference for the user's subsequent adjustment to ensure accurate and effective control of the electromagnetic transmission efficiency.

[0093] The second adjusting mechanism 5 can be slidably connected to the supporting member 6. Specifically, if the second adjusting mechanism 5 has a pulley or a slider that cooperates with the supporting member 6, a slideway can be adaptively provided on the supporting member 6.

[0094] Based on any of the above embodiments, the projection of the first adjusting mechanism 4 on the first plane partially overlaps or completely overlaps with the projection of the second adjusting mechanism 5 on the first plane, and the first plane is a plane perpendicular to the height direction of the support member 6 .

[0095] Please refer to Figure 1 , Figure 2The first plane is a plane perpendicular to the height direction of the support member 6. The projection of the first adjusting mechanism 4 on the first plane is less than or equal to the projection of the second adjusting mechanism 5 on the first plane, so as to minimize magnetic leakage. More specifically, the projection of the first adjusting mechanism 4 on the first plane partially overlaps with or completely overlaps with the projection of the second adjusting mechanism 5 on the first plane, so that the second adjusting mechanism 5 can cover a larger part of the radiation range of the first adjusting mechanism 4, thereby avoiding magnetic leakage as much as possible, reducing the leakage of magnetic field energy, reducing electromagnetic leakage efficiency, and ensuring the reliable transmission performance of electromagnetic wave signals.

[0096] The projections of the first adjusting mechanism 4 and the second adjusting mechanism 5 on the first plane may be square, circular, trapezoidal or other irregular shapes, and the projection shapes of the two may be consistent or inconsistent without limitation.

[0097] In one embodiment, the length of the second adjustment mechanism 5 is greater than the length of the first distance space, and the length of the first adjustment mechanism 4 is less than the length of the first distance space. In this case, the second adjustment mechanism 5 can cover most of the radiation range of the first adjustment mechanism 4 to avoid magnetic leakage.

[0098] In another embodiment, the length of the second adjustment mechanism 5 is equal to the length of the first adjustment mechanism 4 and both are smaller than the length of the first distance space. In this case, the second adjustment mechanism 5 can cover part of the radiation range of the first adjustment mechanism 4 to avoid magnetic leakage.

[0099] The specific application situations in the above two embodiments can be selected in combination with actual use requirements, and are specifically determined based on the leakage magnetic efficiency under the premise of not affecting the electromagnetic transmission performance under the user's requirements.

[0100] On the basis of any of the above embodiments, the first adjustment mechanism 4 includes a first base 41 and at least three first metal plates 42 arranged on the first base 41, the intervals between adjacent first metal plates 42 form a second distance space, and at least one of the three first metal plates 42 is electrically connected to the transmission waveguide 3;

[0101] The second adjustment mechanism 5 includes a second base 51 and at least three second metal plates 52 arranged on the second base 51, and the intervals between adjacent second metal plates 52 form a third distance space arranged opposite to the second distance space, and one second distance space corresponds to at least one third distance space;

[0102] The first metal plate 42 and the second metal plate 52 are both arranged perpendicular to the axial direction of the transmission waveguide line 3 .

[0103] Please refer to Figure 1 , Figure 6 , Figure 7The first adjustment mechanism 4 includes a first base 41 and at least three first metal plates 42 integrally formed therewith. The first base 41 is also made of metal. The first base 41 is arranged parallel to the axial direction of the transmission waveguide 3, and the first metal plates 42 are arranged perpendicular to the transmission waveguide 3. One of the at least three first metal plates 42 is electrically connected to the transmission waveguide 3 to transmit current.

[0104] It should be noted that the lengths of the first metal plate 42 and the first base 41 are both smaller than the length of the first distance space, ensuring that the first adjustment mechanism 4 is only in contact with the transmission waveguide line 3 .

[0105] Please refer to Fig. 9 , Fig.10 The second adjustment mechanism 5 includes a second base 51 and at least three second metal plates 52 integrally formed therewith. The second base 51 is made of metal and is arranged parallel to the axial direction of the transmission waveguide line 3. The second metal plate 52 is arranged perpendicular to the transmission waveguide line 3 to cut the magnetic flux lines in the first distance space to generate an oscillating current.

[0106] Please refer to Figure 8 , Fig.10 The intervals between adjacent first metal plates 42 form a second distance space, and the intervals between adjacent second metal plates 52 form a third distance space arranged opposite to the second distance space. One second distance space corresponds to at least one third distance space.

[0107] When one second distance space corresponds to one third distance space, the number of the first metal plates 42 and the second metal plates 52 are the same. However, in actual application, under the requirement that the projection of the first adjustment mechanism 4 on the horizontal plane partially overlaps or completely overlaps the projection of the second adjustment mechanism 5 on the horizontal plane, the number of the second metal plates 52 can be appropriately increased, so that one second distance space corresponds to two or more third distance spaces, so as to increase the number of times the magnetic flux lines are cut and increase the generated electrical energy.

[0108] Based on any of the above embodiments, at least three first metal plates 42 have at least two height values ​​relative to the first base 41, and the height value of the first metal plate 42 electrically connected to the transmission waveguide 3 is greater than the height value of other first metal plates 42;

[0109] Alternatively, the heights of at least three first metal plates 42 relative to the first base 41 are the same.

[0110] Please refer to Figure 5 , Figure 6In one embodiment, taking the case where the first adjustment mechanism 4 has three first metal plates 42 and the middle first metal plate 42 is electrically connected to the transmission waveguide wire 3, the height values ​​of the two metal plates on the left and right sides of the three first metal plates 42 relative to the first base 41 may be consistent or inconsistent, but the height values ​​of the two metal plates on the left and right sides are both lower than the height of the metal plate on the middle side, which does not affect the divergence of the electromagnetic field magnetic flux lines in the first distance space.

[0111] In another embodiment, in one embodiment, taking the example that the first adjustment mechanism 4 has three first metal plates 42, and the middle first metal plate 42 is electrically connected to the transmission waveguide line 3, the three first metal plates 42 have the same height relative to the first base 41. After the middle metal plate is connected to the transmission waveguide line 3, the transmission waveguide line 3 as a whole is lower than the first metal plate 42, and will not affect the divergence of the electromagnetic field magnetic flux lines in the first distance space.

[0112] Based on any of the above embodiments, at least three second metal plates 52 have the same height relative to the second base 51 , and at least one of the three second metal plates 52 is aligned with the center of the first metal plate 42 electrically connected to the transmission waveguide line 3 .

[0113] Please refer to Figure 8 , Fig.10 In one embodiment, taking the second adjustment mechanism 5 having three second metal plates 52 as an example, the three second metal plates 52 have the same height relative to the second base 51, and the middle metal plate is aligned with the center of the first metal plate 42 electrically connected to the transmission waveguide line 3 to cut most of the magnetic flux lines, and the two metal plates on both sides are used to reduce the leakage magnetic field. In the actual operation process, there is also a situation where a small part of the magnetic flux lines are cut.

[0114] In another embodiment, taking the second adjustment mechanism 5 having five second metal plates 52 as an example, at least one of the three metal plates located in the middle position is aligned with the center of the first metal plate 42 .

[0115] Based on any of the above embodiments, at least two support members 6 are symmetrically arranged on both sides of the second adjustment mechanism 5 , and the distance of the space formed by the at least two support members 6 is greater than the length of any one of the first adjustment mechanism 4 and the second adjustment mechanism 5 .

[0116] Please refer to Figure 1 , Figure 2At least two support members 6 are symmetrically arranged on both sides of the second adjustment mechanism 5, and support members 6 may be arranged on both the left and right sides of the second adjustment mechanism 5. A movable space of the second adjustment mechanism 5 is formed by multiple support members 6. The distance of this movable space is greater than the length of either the first adjustment mechanism 4 or the second adjustment mechanism 5 and is not less than the length of the first distance space, so as to provide reliable support for the input waveguide port 1 and the output waveguide port 2 while avoiding magnetic leakage.

[0117] As a specific implementation, two support members 6 are symmetrically arranged on both sides of the second adjustment mechanism 5 in the length direction to form an open structure. Electromagnetic waves are transmitted as open waveguides in the open structure. The top of the support member 6 is designed to match the shape of the input waveguide port 1 or the output waveguide port 2 to ensure a reliable support effect. In addition, in order to ensure the reliability of the sliding of the second adjustment mechanism 5 when only two support members 6 are used, reinforcement blocks can be connected to the outer sides of the two support members 6 to ensure the stability and reliability of the support members 6 and improve user satisfaction.

[0118] On the basis of providing two support members 6 , the sizes, shapes, etc. of the two support members 6 can be consistent to ensure symmetry and support stability.

[0119] As a specific implementation, the top of the support member 6 has a groove, which can be specifically an arc-shaped bottom. The top extends outward relative to the bottom, and the opening of the top is larger than the arc diameter of the bottom arc, so as to facilitate the connection between the support member 6 and the input waveguide port 1 or the output waveguide port 2, thereby improving the convenience of connection between the two.

[0120] As another specific implementation, the top of the support member 6 has a circular hole, the diameter of which is slightly larger than the outer diameter of the input waveguide port 1 or the output waveguide port 2. When connecting, the input waveguide port 1 or the output waveguide port 2 can pass through the circular hole.

[0121] The shapes of the tops of the two types of support members 6 can be selected based on actual conditions. If the input waveguide port 1 or the output waveguide port 2 is not convenient to move or operate, a groove shape is set on the top of the support member 6; if the support member 6 is fixed in advance and is not convenient to move or operate, either a groove shape or a circular hole can be set on the top of the support member 6.

[0122] Based on any of the above embodiments, the length of the first metal plate 42 is smaller than the length of the second metal plate 52 , and there is a gap between both ends of the second metal plate 52 and the support member 6 .

[0123] Please refer to Figure 1 , Figure 2 , Figure 5 , Fig. 9The length of the first metal plate 42 is smaller than that of the second metal plate 52, so that the second adjustment mechanism 5 can cover the radiation range of the first adjustment mechanism 4 and reduce magnetic leakage. Furthermore, there is a gap between the two ends of the second metal plate 52 and the support member 6, and the second base 51 and the support member 6 are connected to realize the installation of the second adjustment mechanism 5.

[0124] Based on any of the above embodiments, the number of the second metal plates 52 is not less than the number of the first metal plates 42 .

[0125] The number of the second metal plates 52 is greater than or equal to the number of the first metal plates 42, so that the second adjustment mechanism 5 can increase the number of times the magnetic flux lines are cut and increase the generated electrical energy. For example, if three first metal plates 42 are provided, three, four or five second metal plates 52 can be provided.

[0126] Based on any of the above embodiments, the support member 6 is a plate, the top of the support member 6 and the bottom of the first adjustment mechanism 4 are respectively located on both sides of the plane of the transmission waveguide line 3, and the top of the support member 6 is at a distance from the plane.

[0127] Please refer to Figure 1 , Figure 3 , Figure 4 The support member 6 is specifically a plate member, and the top of the support member 6 and the bottom of the first adjustment mechanism 4 are respectively located on both sides of the plane of the transmission waveguide 3, and can also be regarded as being located on both sides of the axis of the transmission waveguide 3, corresponding to Figure 1 The two sides here are the upper and lower sides.

[0128] The top of the support member 6 has a distance from the plane, that is, Figure 1 There is a distance in the up and down directions in the transmission waveguide line 3, the input waveguide port 1, and the output waveguide port 2 are coaxially arranged. By limiting the positions of the top of the support member 6 and the first adjustment mechanism 4 relative to the plane of the transmission waveguide line 3, on the one hand, reliable support for the input waveguide port 1 and the output waveguide port 2 can be guaranteed, and on the other hand, the electromagnetic waves transmitted by the first adjustment mechanism 4 can be adjusted in the space formed between the two support members 6 through the shielding effect of the support member 6, thereby reducing magnetic leakage; on the other hand, it can also limit the second adjustment mechanism 5 slidably connected to the support member 6 and the first adjustment mechanism 4 to maintain a certain distance, so that even if the second adjustment mechanism 5 moves to the upper limit position, it will not contact the first adjustment mechanism 4.

[0129] In this embodiment, the distance may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc., and may be designed based on the actual processing accuracy capability.

[0130] Based on any of the above embodiments, the width of the first adjustment mechanism 4 , the width of the second adjustment mechanism 5 , the diameters of the input waveguide port 1 and the output waveguide port 2 are all smaller than the width of the support member 6 .

[0131] Please refer to Figure 1 , Figure 2 The centers of the first adjustment mechanism 4 and the second adjustment mechanism 5 are aligned to cooperate with each other to change the impedance of the transmission waveguide line 3. The widths of the first adjustment mechanism 4 and the second adjustment mechanism 5 are both smaller than the width of the support member 6, ensuring that the adjustment space of the adjustment mechanism is contained in the space formed by at least two support members 6, thereby ensuring a reliable adjustment effect of the adjustment mechanism.

[0132] The diameters of both the input waveguide port 1 and the output waveguide port 2 are smaller than the width of the support member 6, thereby ensuring a reliable support effect.

[0133] In this embodiment, as a specific implementation, the first adjustment mechanism 4, the second adjustment mechanism 5, the input waveguide port 1 and the output waveguide port 2 all correspond to positions close to the middle in the width direction of the support member 6 to facilitate adjustment.

[0134] Based on any of the above embodiments, the four values ​​corresponding to the width of the first adjustment mechanism 4, the width of the second adjustment mechanism 5, and the diameters of the input waveguide port 1 and the output waveguide port 2 include values ​​that are smaller than the width of the support member 6, and also include values ​​that are equal to the width of the support member 6. For example, the diameters of the input waveguide port 1 and the output waveguide port 2 can be set to be equal to the width of the support member 6. Flexible changes can be made based on actual operational requirements to ensure the adjustment effect of the adjustment mechanism (minimizing magnetic leakage as much as possible while achieving control of the transmission efficiency) and to ensure the support effect of the support member 6 on the output / output port.

[0135] On the basis of any of the above embodiments, a slide groove is provided on the inner wall surface of the support member 6, and the end of the second adjustment mechanism 5 is slidably connected to the slide groove;

[0136] A limiter is provided on the slide slot to limit the sliding distance of the second adjustment mechanism 5;

[0137] A stopper is also provided on the inner wall surface of the support member 6. The stopper is arranged to avoid the slide groove. The stopper extends to lock the sliding of the second adjustment mechanism 5 or retracts to unlock the second adjustment mechanism 5.

[0138] A scale area or a marking area is provided on the inner wall surface of the support member 6;

[0139] Or, a scale area or a marking area is provided on the outer wall surface of the support member 6;

[0140] Alternatively, the inner wall surface and the outer wall surface of the support member 6 are provided with a scale area and a marking area.

[0141] Please refer to Figure 1 , Figure 3 , Figure 4 A slide groove is provided on the inner wall surface of the support member 6. The support member 6 has a certain thickness. The depth of the slide groove is less than the thickness of the support member 6. The end of the second adjustment mechanism 5 is slidably connected to the slide groove to enable the second adjustment mechanism 5 to slide toward or away from the first adjustment mechanism 4, thereby achieving the adjustment of the impedance of the transmission waveguide line 3.

[0142] The length of the chute is set according to the actual adjustment requirements, and is specifically defined according to the user's adjustment range for electromagnetic transmission efficiency. However, it should be noted that during the adjustment process, the second adjustment mechanism 5 and the first adjustment mechanism 4 are not in contact, and a certain distance must be formed between the two to affect the original electromagnetic field of the transmission waveguide 3. When the chute is set on the support 6, when the second adjustment mechanism 5 moves to the top of the chute, there is still a distance between the top of the second adjustment mechanism 5 and the bottom of the first adjustment mechanism 4.

[0143] In this embodiment, the slide groove is preferably a non-through slide groove to avoid magnetic leakage problems.

[0144] A limit member is provided on the slide groove, which is used to limit the sliding distance of the second adjusting mechanism 5. Specifically, the limit member is used to limit the second adjusting mechanism 5 from moving to the point of sliding off the support member 6 or slipping off the support member 6, and the second adjusting mechanism 5 is limited to slide only within the effective length range of the slide groove, thereby ensuring the reliable stability of the second adjusting mechanism 5 during adjustment.

[0145] If the end of the second adjusting mechanism 5 is in the form of a slider, the limiter can be set slightly larger than the slider to ensure reliable limitation of the extreme sliding position of the second adjusting mechanism 5 and ensure reliable and safe sliding of the second adjusting mechanism 5.

[0146] In this embodiment, the limiting member may be a stop block arranged on the slide slot, and when the second adjusting mechanism 5 slides to the position of the stop block, it will be restricted from sliding; it may also be a limiting bar arranged on the slide slot that can be extended into or moved out of the slide slot, and the limiting bar can be extended into the slide slot to limit the sliding of the second adjusting mechanism 5.

[0147] The specific position of the limiter on the slide can be designed according to the actual situation. It can be set at the end, or between the end and the middle. It can be designed according to the actual installation situation.

[0148] A stopper is also provided on the inner wall surface of the support member 6, and the stopper extends to lock the sliding of the second adjustment mechanism 5 or retracts to unlock the second adjustment mechanism 5. Taking a specific implementation as an example, a plurality of groups of baffles are provided in the height direction of the support member 6, and each group of baffles corresponds to a transmission efficiency adjustment position. The baffle passes through the support member 6 and extends between the two support members 6 to form a blockage, and the baffle moves out between the two support members 6 to release the blockage. The process of moving the baffle out can make the end of the baffle close to the support member 6 move out to a position flush with the inner wall of the support member 6, and it is not necessary to completely remove the baffle, thereby improving the convenience of operation. Each group of baffles includes at least two baffles, which are used to limit the upper and lower positions of the second adjustment mechanism 5.

[0149] It should be noted that the baffle can extend between the two support members 6, and the corresponding support member 6 should be provided with a hole for the baffle to pass through. This hole is set at a position avoiding the slide groove, does not interfere with the slide groove, and does not affect the normal sliding of the second adjustment mechanism 5.

[0150] Under the condition of meeting the use requirements, if the overall volume and weight of the second adjustment mechanism 5 are small, the stop member can be arranged on any one of the two support members 6, so as to simplify the overall structure, reduce the complexity of operation and reduce the use cost.

[0151] In actual use, in the original state, the second adjustment mechanism 5 is limited by the baffle to a certain height of the support member 6, corresponding to the electromagnetic conduction efficiency value under a certain customer demand;

[0152] In the adjustment state, the end of the baffle is moved out from the area between the two support members 6 to a position flush with the inner wall of the support member 6. At this time, the second adjustment mechanism 5 can be pushed to slide to reach the electromagnetic conduction efficiency value corresponding to another customer's demand;

[0153] In the adjusted state, after the adjustment is completed, the baffle is inserted into the area between the two support members 6 to form a second restriction on the second adjustment mechanism 5.

[0154] In one embodiment, a scale area or a marking area is provided on the inner wall surface of the support member 6, so that the operator can know the moving distance of the second adjustment mechanism 5 and the transmission power corresponding to the user's needs from the inner wall surface.

[0155] In another embodiment, a scale area or a marking area is provided on the outer wall surface of the support member 6, so that the operator can know the moving distance of the second adjustment mechanism 5 and the transmission power corresponding to the user's needs from the outer wall surface.

[0156] In another embodiment, scale areas and marking areas are provided on the inner and outer walls of the support member 6, so that the operator can know the moving distance of the second adjustment mechanism 5 from both the inner and outer walls, so as to transmit power corresponding to user needs.

[0157] When in use, the scale area or the marking area can be used selectively or both can be used. If one is used selectively, either the scale area or the marking area is used to indicate the moving distance or the transmission efficiency of the second adjustment mechanism 5; if both are used, one is used to indicate the moving distance of the second adjustment mechanism 5, and the other indicates the transmission efficiency.

[0158] The marking area may be in any form such as text, patterns, numbers, raised blocks, grooves, etc., as long as it can indicate the electromagnetic transmission efficiency corresponding to different heights of the support member 6 or indicate the moving distance of the second adjustment mechanism 5.

[0159] On the basis of any of the above embodiments, a plurality of fixed position points are provided in the first distance space, and the second adjustment mechanism 5 can be moved to each fixed position point and locked at the fixed position point by a stop member.

[0160] There are multiple fixed position points in the height direction of the first distance space, each fixed position point corresponds to an impedance value of a resonant circuit and an electromagnetic transmission efficiency. There is no restriction on how the fixed position points are marked, and at least one of the distance, transmission efficiency, impedance value, etc. can be marked to facilitate convenient adjustment by the operator.

[0161] When the second adjustment mechanism 5 moves to each fixed position point, it can be locked at this fixed position point by a stop member, corresponding to a fixed transmission efficiency under user requirements.

[0162] In addition to the above-mentioned electromagnetic transmission efficiency regulator, the present invention further provides a microwave transmission device, comprising: an electromagnetic transmission efficiency regulator, which is the electromagnetic transmission efficiency regulator described in any of the above-mentioned embodiments;

[0163] A first coaxial waveguide structure connected to the input waveguide port 1;

[0164] The second coaxial waveguide structure is connected to the output waveguide port 2 .

[0165] The electromagnetic waves transmitted by the first coaxial line waveguide structure are regulated by the electromagnetic transmission efficiency regulator and transmitted to the second coaxial line waveguide structure at a transmission efficiency that meets user requirements, thereby achieving a low-cost regulation effect.

[0166] In addition to the above-mentioned electromagnetic transmission efficiency regulator, the present invention also provides a regulation method of the electromagnetic transmission efficiency regulator disclosed in the above-mentioned embodiment, and the regulation method includes:

[0167] Adjust the adjustment mechanism to be in the locked state or the operating state;

[0168] In the operating state, adjusting the position of the adjusting mechanism so that it corresponds to a plurality of fixed position points in the first distance space;

[0169] In the locked state, the adjustment mechanism is fixed at any fixed position point.

[0170] The adjusting mechanism is adjusted to be in a locked state or an operating state, specifically, the locking and operating state switching of the adjusting mechanism is achieved through a stop member, specifically, the locking and operating state switching of the second adjusting mechanism 5 is achieved. In the operating state, the position of the second adjusting mechanism 5 is adjusted to change the distance between it and the first adjusting mechanism 4 so that it corresponds to multiple fixed position points in the first distance space. Each movement to a fixed position point corresponds to adjusting the impedance of the electromagnetic wave once, and adjusting the electromagnetic transmission efficiency once.
