Description

Technical Field

[0001] The present application relates to the technical field of radio frequency signal transmission, and in particular to a signal transmission structure and an antenna device for connecting a strip line and a microstrip line. Background Art

[0002] An antenna is a converter that converts the signal propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. It is widely used in radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc. In the antenna, the RF signal needs to be transmitted from the RF components such as connectors, filters, combiners, power division networks, phase shifters, etc. to the antenna transmitting unit and finally radiated into the air. There are different forms of transmission lines in the transmission process, and some forms of transmission lines cause greater signal loss, while some forms of transmission lines cause less signal loss. However, due to the internal space size limitations of the antenna or other design constraints, it is often difficult to unify the transmission line into the same form. Therefore, it is necessary to design a conversion structure between different transmission lines, especially the need to convert from a high-loss transmission line form to a low-loss transmission line form to transmit signals with lower loss. In the field of antennas, commonly used RF transmission lines include microstrip lines, strip lines, coaxial lines, waveguides, parallel double lines, etc. Among them, microstrip lines are the most widely used due to their easy integration with other components. However, in related technologies, both microstrip lines and strip lines have high losses, and the conversion settings between strip lines and microstrip lines occupy a lot of height space, which is a technical problem that needs to be solved urgently. Summary of the invention

[0003] In view of this, a signal transmission structure and an antenna device for connecting a stripline and a microstrip line are proposed.

[0004] In a first aspect, an embodiment of the present application provides a signal transmission structure for connecting a stripline and a microstrip line, comprising:

[0005] A grounding member is provided below at least one of the strip line and the microstrip line, and is used to serve as a grounding for the microstrip line and the strip line, and to variably adjust the height between the strip line and the microstrip line so that one end of the strip conductor of the strip line and one end of the microstrip conductor of the microstrip line are in contact and connected together.

[0006] Through the first aspect, the strip conductor of the strip line is directly connected to the microstrip conductor of the microstrip line by means of a grounding member, so that the transition from the strip line to the microstrip line can be achieved while reducing the height space occupied by the signal transmission structure.

[0007] In combination with the first aspect, in a first possible implementation manner of the signal transmission structure, the grounding member includes an elastic supporting member.

[0008] The elastic support member is located below the strip line or the microstrip line. Optionally, the elastic support member is close to the connection position between the strip line and the microstrip line, and uses elastic deformation to adjust the height of the supported strip line or the microstrip line.

[0009] In combination with the first possible implementation, in a second possible implementation of the signal transmission structure, the elastic support member includes a first body and at least one first elastic component. The first elastic component is located on the first surface and / or the second surface of the first body, and the first elastic component is at least partially in contact with the supported strip line or the microstrip line.

[0010] Through the second possible implementation method, by setting up an elastic support member, the height of the strip line or microstrip line can be adjusted by utilizing elastic deformation, thereby avoiding the adverse effects of errors generated during processing, assembly, etc. on the spatial relative position of the strip line and the microstrip line, thereby ensuring that the microstrip conductor and the strip line are always in contact and connected together in a similar or identical plane.

[0011] In combination with the second possible implementation manner, in a third possible implementation manner of the signal transmission structure, the first body and the at least one first elastic component are an integral structure.

[0012] The third possible implementation method can simplify the processing process of the elastic support member, improve the structural stability and deformability balance of the elastic support member, so that the height of the microstrip line or strip line supported by the elastic support member is more stable.

[0013] In combination with the second possible implementation manner, in a fourth possible implementation manner of the signal transmission structure, the first elastic component includes at least one of the following:

[0014] A first elastic protrusion is provided on the first surface and / or the second surface of the first body,

[0015] A first fixed portion and a first elastic movable portion are connected together, wherein the first fixed portion is connected to the first body, and the first elastic movable portion is suspended above the first surface or the second surface of the first body.

[0016] In combination with the second, third, and fourth possible implementations, in a fifth possible implementation of the signal transmission structure, the grounding component further includes a grounding adapter, the microstrip line further includes a microstrip conductor ground, and a microstrip dielectric layer located between the microstrip conductor ground and the microstrip conductor.

[0017] The ground adapter is provided with a first bearing surface and a second bearing surface, wherein the first bearing surface and the second bearing surface are respectively parallel to the bottom surface of the ground adapter.

[0018] The microstrip line is arranged on the first bearing surface, and the microstrip conductor contacts the first bearing surface;

[0019] The strip line is arranged on the second bearing surface, so that the strip line is located above the microstrip line, and one end of the strip line contacts and is connected to one end of the microstrip line;

[0020] The elastic support member is located on the first bearing surface or the second bearing surface and is close to a connection between the first bearing surface and the second bearing surface.

[0021] According to the fifth possible implementation method, a ground adapter is provided to provide different height planes for the microstrip line and the strip line, and combined with the height adjustable performance of the elastic support, the microstrip conductor and the strip line are always connected together in a similar or identical plane, thereby realizing the connection between the microstrip line and the strip line in the same height space.

[0022] In combination with the first aspect, in a sixth possible implementation of the signal transmission structure, the grounding member includes an elastic transition member, which is located between the connecting surfaces of the strip line and the microstrip line, and the first surface of the elastic transition member is in contact with the strip line, and the second surface of the elastic transition member is in contact with the microstrip line, and the distance between the connecting surfaces of the strip line and the microstrip line is adjusted by elastic deformation.

[0023] According to the sixth possible implementation, the error generated during the processing and assembly of the microstrip line and the strip line can be compensated by setting the elastic adapter, ensuring that the first surface of the elastic adapter is in contact with the strip line, and the second surface of the elastic adapter is in contact with the microstrip line, thereby ensuring the reliability and stability of the strip conductor and the microstrip conductor in the connection state. At the same time, since the elastic adapter has a certain elasticity, after the connection between the microstrip line and the strip line is completed, elastic deformation will occur under force, adjusting the distance between the connection surfaces of the strip line and the microstrip line, thereby ensuring the stability of the distance between the connection surfaces of the strip line and the microstrip line.

[0024] In combination with the sixth possible implementation, in a seventh possible implementation of the signal transmission structure, the elastic adapter includes an annular second body and a plurality of second elastic components, the second elastic components are located on the first surface and / or the second surface of the protruding portion of the second body, and the second elastic components are at least partially in contact with the microstrip line or the strip line.

[0025] In combination with the seventh possible implementation manner, in an eighth possible implementation manner of the signal transmission structure, the second elastic component includes at least one of the following:

[0026] a second elastic protrusion, provided on the first surface and / or the second surface of the protruding portion of the second body;

[0027] The second fixed portion and the second elastic movable portion are connected together, the second fixed portion is connected to the protruding portion of the second body, and the second elastic movable portion is suspended above the first surface or the second surface of the protruding portion of the second body.

[0028] In combination with the seventh possible implementation, in a ninth possible implementation of the signal transmission structure, the second body and the plurality of second elastic components are an integrated structure, which can improve the stability of the elastic adapter structure and the degree of deformation balance, so that the distance between the connection surfaces of the stripline and the microstrip line is more stable.

[0029] In combination with the first aspect and any one of the several possible embodiments of the first aspect, in a tenth possible implementation manner of the signal transmission structure, the direct connection between the strip conductor and the microstrip conductor is achieved by welding, fastener connection or coupling connection.

[0055] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0056] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0057] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0058] In order to solve the above technical problems, the present application provides a signal transmission structure for connecting strip lines and microstrip lines. The signal transmission structure of the embodiment of the present application can realize the connection conversion between strip lines and microstrip lines, and the height space occupied is small. The strip lines and microstrip lines have low signal loss, and can be applied to devices in antenna devices that need to use strip lines and microstrip lines, thereby realizing signal reception and transmission.

[0059] Figure 1A A schematic diagram showing the structure of an antenna device according to an embodiment of the present application is shown. Figure 1B FIG. 2 shows a schematic diagram of a circuit structure of an antenna device according to an embodiment of the present application. Figure 1AAs shown, the antenna device may include a pole 01, an antenna adjustment bracket 02, an antenna 03, a feeder 04, a grounding device 05, and a joint seal 06. The antenna 03 is fixed to the pole 01 through the antenna adjustment bracket 02, and the antenna adjustment bracket 02 can adjust the position of the antenna 03 on the pole 01, the angle between the antenna 03 and the pole 01, etc. The antenna 03 is connected to the grounding device 05 through the feeder 04. The joint seal 06 is provided at the connection between the feeder 04 and the antenna 03 and the connection between the feeder 04 and the grounding device 05, and the joint seal 06 may include an insulating sealing tape, etc.

[0060] like Figure 1B As shown, the antenna 03 may include a radiation unit 031, a phase shifter 032, a combiner (or filter) 033, a transmission or calibration network 034 (which may include a transmission component and / or a calibration network), an antenna connector 035, an antenna cover 036 and a reflector (not shown in the figure). The antenna cover 036 serves as the outer cover (i.e., the shell) of the antenna 03, and is used to cover the components of the antenna 03 except the antenna connector 035 therein to protect the antenna. The radiation unit 031 may also be called an antenna vibrator, a vibrator, etc., which is a basic component unit of the antenna and is used to receive and / or transmit wireless signals. The reflector, also called a bottom plate, an antenna panel, a metal reflective surface, a metal reflective plate, etc., is used to improve the sensitivity of the antenna to wireless signal reception, and can reflect and gather the antenna signal at the receiving point. While enhancing the receiving / transmitting capability of the antenna, it also plays a role in blocking and shielding the interference of other wireless signals from the back (opposite direction) to the received signal. The antenna connector 035 is used to be connected to a grounding device through a feeder.

[0061] The antenna 03 includes at least one independent array and a feeding network corresponding to each array, each array includes a radiation unit 031 and a reflector, wherein the frequencies of the radiation units 031 in different independent arrays may be the same or different, and the radiation units 031 are usually placed above the reflector. Each array receives or transmits a wireless signal through its own feeding network. The feeding network is composed of a controlled impedance transmission line, which is used to feed the transmission signal to the radiation unit 031 according to a specified amplitude and phase, and to send the received signal received by the radiation unit 031 to the signal processing unit of the base station where the antenna is located according to the specified amplitude and phase. The feeding network includes at least a phase shifter 032, and may also include a combiner 033, a filter, a transmission or calibration network 034. The feeding network can realize the directional adjustment of different radiation beams (adjusting the receiving direction of the received wireless signal and / or the beam direction of the transmitted wireless signal) through the transmission components, and can also obtain the calibration signal required by the antenna 03 through the calibration network.

[0062] In the embodiments of the present application, microstrip lines and / or strip lines can be arranged inside the above-mentioned power divider, combiner, phase shifter, radiation unit, and filter to perform signal transmission within the device and / or between devices, and the signal transmission structure can be used to achieve the connection between the strip line and the microstrip line.

[0063] To further describe the manner in which the signal transmission structure realizes the connection between the stripline and the microstrip line, the signal transmission structure and the stripline and microstrip line connected by the signal transmission structure are described by the following examples:

[0064] Figure 2A shows a cross-sectional view of a strip line according to an embodiment of the present application, Figure 2B-Figure 2D FIG. 2 shows a schematic diagram of the structure of a strip line according to an embodiment of the present application. Figure 2A and Figure 2B As shown, the stripline includes a first conductor ground 11, a second conductor ground 12, a stripline wire 13 and a first fixing member 14. The first conductor ground 11, the second conductor ground 12 and the stripline wire 13 are parallel to each other. The stripline wire 13 is located in the middle between the first conductor ground 11 and the second conductor ground 12, that is, the distance between the stripline wire 13 and the first conductor ground 11 is the same as the distance between the stripline wire 13 and the second conductor ground 12.

[0065] The first fixing member 14 may be one or more (such as Figure 2A As shown in the figure, the strip conductor 13 is fixed at the middle position between the first conductor ground 11 and the second conductor ground 12. The number of the first fixing members 14 can be set according to the length of the strip conductor, etc. The material used for the first fixing member is a material with a small dielectric loss tangent (i.e., a small dielectric loss angle), a low dielectric constant, and good temperature resistance. For example, the first fixing member can be selected from a material with a dielectric loss tangent value of less than 0.005 and a dielectric constant of less than 4C2 / (N·M 2 ), a plastic material with a temperature resistance range of -40°C to 55°C. The first fixing member 14 can be fixed at one end to the first conductor ground 11 or the second conductor ground 12 (such as Figure 2A As shown in the figure, the other end is fixedly connected to the ribbon conductor 13. Alternatively, the first fixing member 12 can also be fixed at both ends to the first conductor ground 11 and the second conductor ground 12, and a limiting hole is set in the middle position of the first fixing member 12 (so that the ribbon conductor 13 passes through the limiting hole to be fixed), or a fixing protrusion is set (to fix the ribbon conductor 13 on the fixing protrusion), etc. Those skilled in the art can set the implementation method of the first fixing member according to actual needs, and this application does not limit this.

[0066] In one possible implementation, Figure 2CAs shown, the stripline may further include a third conductor ground 15. The third conductor ground 15 is perpendicular to and connected to the first conductor ground 11 and the second conductor ground 12, respectively, and the first conductor ground 11, the second conductor ground 12, and the third conductor ground 15 are connected to form an integrated structure. That is, the first conductor ground 11 and the second conductor ground 12 are respectively located above and below the stripline conductor 13, and the third conductor ground 15 is located on the left or right side of the stripline conductor 13.

[0067] In one possible implementation, Figure 2D As shown, the stripline may further include a third conductor ground 15 and a fourth conductor ground 16 which are parallel to each other, the third conductor ground 15 being perpendicular to and connected to the first conductor ground 11 and the second conductor ground 12 respectively, and the fourth conductor ground 16 being perpendicular to and connected to the first conductor ground 11 and the second conductor ground 13 respectively, so that the first conductor ground 11, the second conductor ground 12, the third conductor ground 15, and the fourth conductor ground 16 are connected into an integrated structure. That is, the first conductor ground 11 and the second conductor ground 12 are respectively located above and below the stripline wire 13, and the third conductor ground 15 and the fourth conductor ground 16 are respectively located on the left and right sides of the stripline wire 13.

[0068] When the space on one side or both sides of the strip line is limited or the strip line needs to be isolated from other components or systems, the third conductor ground and / or the fourth conductor ground may be added or removed to enhance the isolation.

[0069] By the above method, a stripline with air as the medium is provided, which can reduce the signal loss in the stripline. In addition, since air is used as the medium of the stripline, it is not necessary to perform operations such as manufacturing metallized holes required for connection on the medium of the stripline during the process of connecting the stripline wire with the microstrip wire, the manufacturing process of connecting the stripline wire with the microstrip wire is simplified.

[0070] In a possible implementation, the present application embodiment also provides another strip line, which is Figure 2A-2D The difference between the stripline shown is that a stripline dielectric layer can be provided between the first conductor ground and the second conductor ground in the stripline, and the stripline conductor is provided in the stripline dielectric layer. However, since the stripline dielectric layer can fix the stripline conductor so that it is located in the middle position between the first conductor ground and the second conductor ground, it does not include the above-mentioned first fixing member.

[0071] The present application also provides a microstrip line, such as Figure 8A-8CAs shown, the microstrip line includes a microstrip conductor 21, a second fixing member 24 and a microstrip conductor ground 23, wherein the second fixing member 24 is used to fix the microstrip conductor 21 above the microstrip conductor ground 21. The second fixing member 24 is similar to the first fixing member 14 described above, and the relevant description of the first fixing member can be referred to in order to set the second fixing member 24, which will not be described in detail here.

[0072] The present application also provides another microstrip line, such as Figure 3 , Figure 5A , Figure 5B , Figure 6A-6D , Figure 7A-7D As shown, the microstrip line includes a microstrip conductor 21 , a microstrip conductor ground 23 , and a microstrip dielectric layer 22 located between the microstrip conductor 21 and the microstrip conductor ground 23 .

[0073] An embodiment of the present application provides a signal transmission structure for connecting a stripline and a microstrip line, the signal transmission structure comprising: a grounding member, arranged below at least one of the stripline and the microstrip line, for serving as a ground for the microstrip line and the stripline, and for variably adjusting the height between the stripline and the microstrip line so that one end of the strip conductor of the stripline and one end of the microstrip conductor of the microstrip line are in contact and connected together.

[0074] The grounding element may be connected to the back side of the substrate where the microstrip line and the strip line are located, so that the grounding element may be used as the grounding for the microstrip line and the strip line.

[0075] Through the signal transmission structure provided above, the strip conductor of the strip line can be directly connected to the microstrip conductor of the microstrip line with the help of a grounding member, which can realize the transition from the strip line to the microstrip line while reducing the height space occupied by the signal transmission structure.

[0076] In a possible implementation, one end of the strip conductor is directly connected to the microstrip conductor by welding, connection through fasteners, coupling connection, and other connection methods. Those skilled in the art can set the connection method according to actual needs, and this application does not limit this.

[0077] In this embodiment, the use of a grounding member to achieve the transition from a stripline to a microstrip line may include the following implementation methods. Those skilled in the art may refer to the following implementation methods to set the signal transmission structure. It should be noted that the signal transmission structure shown in the drawings of the present application is only for illustrative purposes only to describe the implementation method of the signal transmission structure to achieve the connection of microstrip lines and striplines. The sizes and proportional relationships of the microstrip lines, striplines, grounding members, etc. shown therein are only for illustration. In actual use, those skilled in the art may make settings according to actual needs, and the present application does not impose any restrictions on this.

[0078] Figure 3A schematic diagram of the connection and use of a signal transmission structure for connecting a stripline and a microstrip line according to an embodiment of the present application is shown. In a possible implementation, Figure 3 As shown, the grounding member may include an elastic supporting member 32 .

[0079] The elastic support member 32 is located on the strip line or the microstrip line (such as Figure 3 As shown in the figure, and close to the connection position A between the strip line and the microstrip line, the height of the supported strip line or the microstrip line is adjusted by elastic deformation.

[0080] Among them, when the first distance from the microstrip conductor 21 to the bottom surface of the microstrip conductor ground 23 is less than the second distance between the strip conductor 13 and the second conductor ground 12, the elastic support member 32 can be arranged below the microstrip line. When the first distance is greater than the second distance, the elastic support member 32 can be arranged below the strip conductor. In addition, the size of the elastic support member can be set according to the difference between the first distance and the second distance. In this way, no matter what the size relationship between the first distance and the second distance is, the microstrip conductor 21 and the strip conductor 13 can be placed in the same or similar plane with the help of the elastic support member, thereby realizing the connection between the microstrip conductor 21 and the strip conductor 13. The way in which one end of the strip conductor 13 is directly connected to the microstrip conductor 21 includes welding, connection through fasteners, coupling connection and other connection methods. Those skilled in the art can set the connection method according to actual needs, and this application does not limit this.

[0081] Among them, the stripline, microstrip line, and elastic support can be installed on the substrate as a whole. When the elastic support 32 is located below the stripline, one end of the second conductor ground 12 contacts the substrate, the microstrip conductor ground 23 is fixed on the substrate, and the elastic support 32 is fixed on the substrate; when the elastic support 32 is located below the microstrip line, one end of the microstrip conductor ground 23 contacts the substrate, the second conductor ground 12 is fixed on the substrate, and the elastic support 32 is fixed on the substrate. And after the installation is completed, since the elastic support is in contact with the microstrip line or stripline and the substrate it supports, when the force applied by the microstrip line or stripline to the elastic support and the force applied by the substrate to the elastic support change, the elastic support will undergo elastic deformation due to the force applied by the microstrip line or stripline it supports and the force applied by the substrate, so as to maintain the stability of the relative position relationship between the microstrip line and the stripline, so as to ensure that one end of the stripline conductor and one end of the microstrip conductor can stably contact and connect together.

[0082] In a possible implementation, the elastic support member 32 may include a first body and at least one first elastic member. The first elastic member is located on the first surface and / or the second surface of the first body, and the first elastic member at least partially contacts the supported strip line or microstrip line.

[0083] When the first elastic component is located on the first surface or the second surface of the first body, the first body can be fixed to the substrate carrying the microstrip line and the strip line by bonding, fixing with fasteners, welding, etc. By setting the elastic support, the height of the strip line or microstrip line can be adjusted by elastic deformation, avoiding the adverse effect of the relative spatial position of the strip line and the microstrip line caused by errors generated during processing and assembly, so as to ensure that the microstrip wire and the strip wire are always in contact and connected together in a similar or identical plane.

Figure 4H-4L As shown, the first elastic protrusion 324 is disposed on the first surface and / or the second surface of the first body 321 .

[0086] in, Figure 4A-4G As shown, the first elastic component may include a first fixing portion 322 and a first elastic moving portion 323. The shape of the first fixing portion 322 may be as follows: Figure 4A-4G The arc shape shown in the figure may also be an elliptical arc or other shape structure that can support the first elastic moving part 323 to float above the first surface and / or the second surface of the first body 321. The first elastic moving part 323 includes a top portion (such as Figure 4A , Figure 4C The top B1 and the top B2 shown are Figure 4A-4B and Figure 4CThe difference between the two elastic supports shown is that the top is different), and the shape of the top includes an arc shape such as B1, a chamfered shape such as a "┌┐" convex shape such as B2, etc., which can ensure that the top is in contact with the microstrip line or strip line without causing damage to the microstrip line or strip line. The first elastic movable part 323 also includes a connecting part connected to the first fixed part 322 and the top, and a movable support part connected to the top, and there is a spacing distance between the movable support part and the first main body 321. In this way, during the installation of the elastic support, when the top of the first elastic movable part 323 is subjected to an increase in force (from the microstrip line or strip line it supports), the top will move in a direction close to the first main body 321, and when the movable support part contacts the first main body 321, the downward movement of the top will stop or slow down under the support of the movable support part to ensure that the first elastic component will not be subjected to excessive force and plastic deformation. On the contrary, when the force on the top of the first elastic movable part 323 (from the microstrip line or strip line it supports) decreases, the top will move away from the first body 321, and the movable support part will continue to move away from the first body 321, and when the force is zero, the elastic support member 32 will return to its original shape. During use, the elastic support member will offset the change in the force on the top of the first elastic movable part 323 through deformation, so that the height of the microstrip line or strip line supported by the elastic support member can be stable.

[0087] The first elastic moving part 323 may be located in a part or the whole area above the first body 321, for example, Figure 4A-4C As shown, the first elastic moving part 323 can be located in the entire area above the first body 321. Figure 4D-Figure 4G As shown, the first elastic moving portion 323 may be located in a partial area above the first body 321, and the partial area may be one side of the long side or short side of the first body 321 (eg Figure 4D-Figure 4G The first body 321 may be one side of the long side of the first body 321, or may be both sides of the long side or short side of the first body 321, or may be a designated area such as the center area on the first body 321. Furthermore, when the first elastic movable portion 323 is located in a partial area above the first body 321, one end of the first body with the first elastic movable portion above the elastic support may be placed near the connection position A between the strip line and the microstrip line, and the other end (without the first elastic movable portion above) may be placed away from A.

[0088] Among them, the plurality of first elastic components in the elastic support member can be as follows Figure 4A-4C The structure connected together by the movable support part etc. as shown in the figure may also be as follows Figure 4D-Figure 4G The structures shown are independently arranged.

[0089] It should be noted that those skilled in the art can set the shape of the first fixed part 322 and the first elastic movable part 323, the relative position with the first body, the size, the number, whether the first elastic movable parts are connected, etc. according to actual needs, and the present application does not impose any restrictions on this.

[0090] In a possible implementation, the shape of the first elastic protrusion 324 may be hemispherical (eg Figure 4H-4L The first elastic protrusion 324 may be a protrusion in the shape of a semi-ellipsoid, a cone (the cone end of the cone may be an arc shape to avoid damage to the microstrip line or strip line), a truncated cone, a prism, a pyramid (the cone end of the pyramid may be an arc shape to avoid damage to the microstrip line or strip line), etc., so that it can support the microstrip line or strip line and can be elastically deformed when subjected to force. The first elastic protrusion 324 may be as follows Fig. 4I , Figure 4L The structure shown protrudes relative to the plane where the first body 321 is located, and no cavity structure is formed between it and the first body 321. The first elastic protrusion 324 can also be as follows Figure 4J The structure shown is installed on the first main body 321, and forms a cavity structure 3241 with the first main body 321; in order to ensure that the first elastic protrusion 324 can undergo elastic deformation normally, a plurality of through holes 3242 can also be provided on the outer shell constituting the cavity structure 3241 (that is, the first elastic protrusion 324 and the first main body 321 at the corresponding position).

[0091] The first elastic protrusion may be in a straight line on the first body (eg Figure 4H-4L ) distribution, or can be distributed in a ring, curve, or array state.

[0092] It should be noted that those skilled in the art can set the shape of the first elastic protrusion, its relative position with respect to the first body, its size, quantity, etc. according to actual needs, and this application does not impose any limitation on this.

[0093] In one possible implementation, Figure 4A-Figure 4I , Figure 4K , Figure 4L As shown, the first main body and the at least one first elastic component are an integrated structure. In this way, the processing process of the elastic support can be simplified, and the structural stability and deformability of the elastic support can be improved, so that the height of the microstrip line or strip line supported by it is more stable.

[0094] Wherein, the first elastic component is as follows Figure 4H , Fig. 4I , Figure 4K , Figure 4L When the first elastic protrusion is shown, the first elastic protrusion can be formed by directly stamping the corresponding position on the first body. Figure 4A-4G The first fixed portion 322 and the first elastic movable portion 323 shown in the figure can be formed by selecting a layered substrate of a certain size, and bending and / or cutting one side thereof to form the “first fixed portion 322 and the first elastic movable portion 323”.

[0095] The microstrip conductor 21 and the strip conductor 13 may be parallel to each other (eg Figure 4A The microstrip conductor 21 and the strip conductor 13 can be adjusted according to the relative angle between the two conductors.

[0096] Figure 5A , Figure 5B A schematic diagram showing the connection and use of a signal transmission structure for connecting a stripline and a microstrip line according to an embodiment of the present application is shown. Figure 5C FIG. 2 shows a three-dimensional schematic diagram of a ground adapter according to an embodiment of the present application. In a possible implementation, as shown in FIG. Figure 5A As shown, the grounding component may further include a grounding adapter 31, and the microstrip line may further include a microstrip conductor ground 23 and a microstrip dielectric layer 22 located between the microstrip conductor ground 23 and the microstrip conductor 21. Figure 5C As shown, the ground adapter 31 is provided with a first bearing surface 311 and a second bearing surface 312, and the first bearing surface 311 and the second bearing surface 312 are respectively parallel to the bottom surface of the ground adapter 31. The first bearing surface 311 and the second bearing surface 312 have different heights corresponding to the bottom surface, and the height of the first bearing surface 311 can be higher than the second bearing surface 312 (such as Figure 5A-Figure 5C ), the height of the first bearing surface 311 may also be lower than the second bearing surface 312.

[0097] like Figure 5A As shown, the microstrip line is arranged on the first bearing surface 311, and the microstrip conductor ground 23 contacts the first bearing surface 311. The stripline is arranged on the second bearing surface 312, so that the stripline conductor 13 is located above the microstrip conductor 21, and one end of the stripline conductor 13 contacts and directly connects with one end of the microstrip conductor 21. The elastic support member 32 is located below the stripline or microstrip line, on the first bearing surface 311 (not shown in the figure) or the second bearing surface 312, and close to the connection between the first bearing surface 311 and the second bearing surface 312.

[0098] By setting up a ground adapter, different height planes are provided for the microstrip line and the strip line, and combined with the height adjustable performance of the elastic support, the microstrip wire and the strip line are always connected together in a similar or identical plane, realizing the transfer of the microstrip line and the strip line in the same height space.

[0099] like Figure 5B As shown, the connection between the microstrip line and the stripline can also be realized by only using a grounding adapter. In this case, the microstrip line is arranged on the first bearing surface 311, and the microstrip conductor ground 23 is in contact with the first bearing surface 311. The stripline is arranged on the second bearing surface 312, so that the stripline conductor 13 is located above the microstrip conductor 21, and one end of the stripline conductor 13 is in contact with one end of the microstrip conductor 21 and is directly connected together. By providing a grounding adapter, different height planes are provided for the microstrip line and the stripline, so that the microstrip conductor and the stripline are always connected together in a similar or identical plane, and the microstrip line and the stripline are switched in the same height space.

[0100] In this implementation, the planes where the microstrip conductor 21 and the strip conductor 13 are located may be parallel to each other (e.g. Figure 5A As shown in FIG. 1 , the microstrip conductor 21 and the strip conductor 13 may be perpendicular to each other or have any angle therebetween. When there is a certain angle between the microstrip conductor 21 and the strip conductor 13, the three-dimensional shape of the ground adapter 31 needs to be adjusted so that the microstrip line is arranged on the first bearing surface and the strip conductor is arranged on the second bearing surface, and the microstrip conductor and the strip conductor can be in contact and connected at the ends of the two lines.

[0101] It is understandable that the embodiments of the present application only exemplarily describe the structures of several elastic support members 32 , and those skilled in the art may configure the structures of the elastic support members 32 according to actual needs, and the present application does not impose any limitation on this.

[0102] Figure 6A-6D FIG. 1 shows a three-dimensional schematic diagram of a signal transmission structure based on a stripline and a microstrip line according to an embodiment of the present application. In a possible implementation, as shown in FIG. Figure 6A-6D As shown, the grounding member may be an elastic adapter 41, which is located between the connection surfaces of the stripline and the microstrip line, and the plane where the microstrip conductor 21 is located is perpendicular to the plane where the stripline conductor 13 is located. The first surface of the elastic adapter 41 contacts the stripline, and the second surface of the elastic adapter contacts the microstrip line, and the distance between the connection surfaces of the stripline and the microstrip line is adjusted by elastic deformation. The connection surface of the stripline is the surface where the stripline contacts the first surface of the elastic adapter, as shown in FIG. Figure 6A-6B In the embodiment, the connection surface of the strip line is the surface where the third conductor ground 15 contacts the first surface of the elastic adapter. Figure 6A-6B In the embodiment, the connection surface of the strip line is the surface where the ends of the first conductor ground 11 and the second conductor ground 12 contact the first surface of the elastic transition member. The connection surface of the microstrip line is the surface that contacts the second surface of the elastic transition member. Figure 6A-6DThe connection surface of the microstrip line is the surface where the microstrip conductor ground 23 contacts the second surface of the elastic transition component.

[0103] The arrangement of the elastic adapter can compensate for the errors generated during the processing and assembly of the microstrip line and the strip line, ensure that the first surface of the elastic adapter contacts the strip line, and the second surface of the elastic adapter contacts the microstrip line, and ensure the reliability and stability of the strip conductor and the microstrip conductor in the connection state. At the same time, since the elastic adapter has a certain elasticity, after the connection between the microstrip line and the strip line is completed, it will undergo elastic deformation under force, adjust the distance between the connection surfaces of the strip line and the microstrip line, and ensure the stability of the distance between the connection surfaces of the strip line and the microstrip line.

[0104] Figure 6E-6J FIG. 4 is a schematic diagram showing the structure of an elastic transition member according to an embodiment of the present application. In a possible implementation, the elastic transition member 41 may include an annular second body 411 (eg, Fig. 6E , Fig.6I , Figure 6G As shown) and a plurality of second elastic components, the second elastic components are located on the first surface and / or the second surface of the protrusion 412 of the second body 411, and the second elastic components are at least partially in contact with the microstrip line or the stripline.

[0105] In this implementation, a plurality of protrusions 412 may be provided on the annular second body 411, and the plurality of protrusions 412 may not contact each other and may be spaced apart, so as to ensure that each second elastic component can be deformed when subjected to force without affecting other second elastic components. The protrusions are provided to protrude relative to the annular structure of the second body, and the shape of the protrusions may be a square, semicircle, semi-ellipse, or other shape that can carry or set the second elastic component. The protrusions 412 may be provided to protrude relative to the outer ring of the annular second body (e.g. Fig. 6F , Figure 6G , Fig.6I ), it may also be arranged to protrude corresponding to the inner ring of the annular second body, or it may be arranged to protrude corresponding to the inner ring and outer ring of the annular second body, and the present application does not impose any limitation on this.

[0106] In this implementation, the second body 411 is set as a ring structure to ensure that one end of the microstrip wire 21 or the strip wire 13 can pass through the elastic adapter 41 to finally achieve the connection between the microstrip wire 21 and the strip wire 13. The inner ring and the outer ring of the second body 411 can be the same or different shapes, such as circular, elliptical, polygonal, etc. The size and shape of the inner ring and the outer ring of the ring-shaped second body can be set according to the size of the strip wire and the setting requirements of the impedance.

[0107] Figure 6K A schematic diagram of a three-dimensional structure of a strip line according to an embodiment of the present application is shown. In a possible implementation, as shown in FIG. Fig. 6A , Figure 6B , Figure 6G As shown, a first through hole 52 is provided on the first conductor ground 11, the second conductor ground 12, the third conductor ground 15 or the fourth conductor ground 16. One end of the strip conductor 13 passes through the first through hole 52 and the annular second body 411 of the elastic transition piece 41 to connect to the microstrip conductor 21.

[0108] In this implementation, the first through hole can be set on a conductor ground among the first conductor ground, the second conductor ground, the third conductor ground and the fourth conductor ground that contacts the elastic adapter 41, and the size and shape of the first through hole can be set according to the size of the strip conductor and the impedance setting requirements.

[0109] Fig. 6E , Fig. 6F 1 and 2 show a front view and a stereoscopic view of a first elastic adapter according to an embodiment of the present application. In a possible implementation, Fig. 6E , Fig. 6F As shown, the second elastic component may include a second elastic protrusion 413 disposed on the first surface and / or the second surface of the protruding portion 412 of the second body 411 . Fig. 6E , Fig. 6F The second elastic protrusion 413 shown is located on the first surface and the second surface of the protruding portion 412 , or may be located only on the first surface or the second surface.

[0110] In this implementation, the shape of the second elastic protrusion may be a hemispherical shape (eg Figure 6E-6F The second elastic protrusion is similar to or identical to the shape of the first elastic protrusion, so that it can be elastically deformed when it is in contact with the microstrip line and / or the strip line. The present application only describes the structure of the second elastic protrusion by way of example, and those skilled in the art can set the structure of the second elastic protrusion according to the needs, and the present application does not limit this.

[0111] Figure 6G , Figure 6H 1 shows a top view and a cross-sectional view of a second elastic transition member according to an embodiment of the present application, Figure 6H The cross section is along Figure 6G The cross section at the location of the dotted line. Fig.6I , Figure 6J 1 shows a top view and a cross-sectional view of a third elastic transition member according to an embodiment of the present application, Figure 6J The cross section is along Fig.6IIn a possible implementation, the second elastic component may include a second fixed portion 415 and a second elastic movable portion 414 connected together, the second fixed portion 415 is connected to the protruding portion 412 of the second body 411, and the second elastic movable portion 414 is suspended above the first surface or the second surface of the protruding portion 412 of the second body 411. Figure 6G , Figure 6H As shown, the plurality of second elastic movable portions 414 may be suspended on the first surface of the protruding portion 412, or the plurality of second elastic movable portions 414 may be suspended on the second surface of the protruding portion 412; Fig.6I , Figure 6J As shown, a plurality of second elastic movable portions 414 may be provided and may be suspended on the first surface and the second surface of the protrusion 412 respectively, and the second elastic movable portions 414 on two adjacent protrusions 412 may be suspended on the first surface and the second surface respectively.

[0112] In this implementation, the settings of the shape, size, number, relative position between the second elastic movable portion 415 and the second elastic movable portion 414, etc. can refer to the relevant settings of the first fixed portion and the first elastic movable portion above, and will not be repeated here.

[0113] By setting the second elastic component, since it has a certain elasticity and can undergo elastic deformation, the second elastic component can change in height due to different forces when in use, thereby adjusting the distance between the connecting surfaces of the strip line and the microstrip line, thereby ensuring the stability of the distance between the connecting surfaces of the strip line and the microstrip line.

[0114] In one possible implementation, Figure 6E-6J The second main body and the plurality of second elastic components may be an integral structure. In this way, the stability of the elastic transition component structure and the degree of deformation balance can be improved, so that the distance between the connection surfaces of the strip line and the microstrip line is more stable.

[0115] In one possible implementation, Figure 6A-6D As shown, the microstrip line further includes a second through hole 25 that penetrates the microstrip conductor ground 23 and the microstrip dielectric layer 22. The manner in which the strip conductor 13 is connected to the microstrip conductor 21 through the elastic transition piece 41 may include any one of the following:

[0116] like Fig. 6A , Figure 6BAs shown, one end of the strip conductor 13 passes through the first through hole 52, the annular second body 411 of the elastic adapter 41, and the second through hole 25 in sequence to be directly connected to the microstrip conductor 21; one end of the microstrip conductor 21 passes through the second through hole 25, the annular second body 411 of the elastic adapter 41, and the first through hole 52 in sequence to be directly connected to the strip conductor 13; one end of the strip conductor 13 passes through the first through hole 52, the annular second body 411 of the elastic adapter 41 in sequence and is connected to the microstrip conductor 21 through the conductive metal in the second through hole 25.

[0117] like Figure 6C , Fig.6D As shown, one end of the strip conductor 13 passes through the annular second body 411 of the elastic adapter 41 and the second through hole 25 in sequence to be directly connected to the microstrip conductor 21; one end of the microstrip conductor 21 passes through the second through hole 25 and the annular second body 411 of the elastic adapter 41 in sequence to be directly connected to the strip conductor 13; one end of the strip conductor 13 passes through the annular second body 411 of the elastic adapter 41 and is connected to the microstrip conductor 21 through the conductive metal in the second through hole 25.

[0118] like Figure 6A-6D In the example given, the relative position relationship between the microstrip conductor and the strip conductor is that the plane where the microstrip conductor is located is perpendicular to the plane where the strip conductor is located. In fact, the extension direction of the microstrip conductor (also called the length direction, such as Fig. 6A The vertical direction where the microstrip conductor 21 is located) and the extending direction of the strip conductor (also referred to as the length direction, such as Figure 6C The horizontal direction where the strip conductor 13 is located) can be parallel to each other (such as Figure 6B ), or it may have a certain angle, such as a right angle (such as Fig. 6A , Figure 6C , Fig.6D ) or any other angle, which is not limited in this application.

[0119] The elastic adapter can realize the connection between the microstrip line and the strip line in the vertical direction (that is, the plane where the microstrip wire is located is perpendicular to the plane where the strip wire is located), and the adverse effects of errors caused by processing and assembly on the connection between the microstrip line and the strip line can be eliminated to ensure that the microstrip wire and the strip wire can be connected vertically.

[0120] Figure 7A-7D FIG. 1 is a three-dimensional schematic diagram showing the connection between a strip line and a microstrip line according to an embodiment of the present application. In a possible implementation, as shown in FIG. Fig. 7A , Figure 7B As shown, the microstrip line and the strip line can be directly connected together. The microstrip line includes a microstrip conductor ground 23, a microstrip wire 21, a microstrip dielectric layer 22 located between the microstrip conductor ground 23 and the microstrip wire 21, and a second through hole 25 that penetrates the microstrip conductor ground 23 and the microstrip dielectric layer. The plane where the microstrip wire 21 is located is perpendicular to the plane where the strip line 13 is located, and the microstrip wire 21 is connected to the strip line 13.

[0121] Among them, in Fig. 7A , 7B As shown, when one end of the first conductor ground 11 and the second conductor ground 12 are in contact with the microstrip conductor ground 23, the strip conductor 13 is connected to the microstrip conductor 21 in any of the following ways:

[0122] One end of the strip conductor 13 passes through the second through hole 25 and is directly connected to the microstrip conductor 21;

[0123] One end of the microstrip conductor 21 passes through the second through hole 25 and is directly connected to the strip conductor 13;

[0124] The strip conductor 13 is connected to the microstrip conductor 21 through the conductive metal in the second through hole 25 .

[0125] In one possible implementation, Figure 7C , Fig.7D As shown, when one side of the first conductor ground 11, the second conductor ground 12, the third conductor ground 15 or the fourth conductor ground 16 contacts the microstrip conductor ground 23, a first through hole 52 is provided on the first conductor ground 11, the second conductor ground 12, the third conductor ground 15 or the fourth conductor ground 16 contacting the microstrip conductor ground 23 (see Figure 6K ), the strip conductor 13 is connected to the microstrip conductor 21 in any of the following ways:

[0126] One end of the strip conductor 13 passes through the first through hole 52 and the second through hole 25 in sequence and is directly connected to the microstrip conductor 21;

[0127] One end of the microstrip conductor 21 passes through the second through hole 25 and the first through hole 52 in sequence and is directly connected to the strip conductor 13;

[0128] The strip conductor 13 passes through the first through hole 52 and is connected to the microstrip conductor 21 through the conductive metal in the second through hole 25 .

[0129] like Figure 7A-7DIn the example given, the relative position relationship between the microstrip conductor and the strip conductor is that the plane where the microstrip conductor is located is perpendicular to the plane where the strip conductor is located. In fact, the extension direction of the microstrip conductor (also called the length direction, such as Fig. 7A , Figure 7B The vertical direction where the microstrip conductor 21 is located) and the extending direction of the strip conductor (also referred to as the length direction, such as Fig. 7A , Figure 7B The horizontal direction where the strip conductor 13 is located) can be parallel to each other (such as Fig.7D ), or it may have a certain angle, such as a right angle (such as Figure 7A-7C ) or any other angle, which is not limited in this application.

[0130] By directly connecting the microstrip line and the stripline together in the above manner, the switching between the microstrip line and the stripline is simplified, and the switching from the stripline to the microstrip line can be realized while reducing the height occupied by the signal transmission structure.

[0131] Fig. 8A , Figure 8B , Figure 8C A schematic diagram showing the connection between a stripline and a microstrip line according to an embodiment of the present application is shown. In a possible implementation, as shown in FIG. Fig. 8A As shown, the microstrip line may include a microstrip conductor 21, a microstrip conductor ground 23 and a second fixing member 24. The microstrip conductor ground 23 and the second conductor ground 12 are in the same plane and connected together. The second fixing member 24 fixes the microstrip conductor 21 above the microstrip conductor ground 23.

[0132] like Fig. 8A As shown, when the distance between the microstrip conductor 21 and the microstrip conductor ground 23 is the same as the distance between the strip conductor 13 and the second conductor ground 12, one end of the strip conductor 13 is directly connected to the microstrip conductor 21. The way in which one end of the strip conductor 13 is directly connected to the microstrip conductor 21 includes welding, connection through fasteners, coupling connection, etc. Those skilled in the art can set the connection method according to actual needs, and this application does not limit this.

[0133] like Figure 8BAs shown, when the distance between the microstrip conductor 21 and the microstrip conductor ground 24 is different from the distance between the strip conductor 13 and the second conductor ground 12, one end of the strip conductor 13 is bent and directly connected to the microstrip conductor 24. Alternatively, one end of the microstrip conductor 21 can be bent and directly connected to the strip conductor 13. The way in which one end of the strip conductor 13 is bent and directly connected to the microstrip conductor 21 includes welding, connection through fasteners, coupling connection, etc., and those skilled in the art can set the connection method according to actual needs, and this application does not limit this.

[0134] like Figure 8C As shown, when the distance between the microstrip conductor 21 and the microstrip conductor ground 24 is different from the distance between the strip conductor 13 and the second conductor ground 12, the strip conductor 13 and the microstrip conductor 21 are connected together through a wire connector 51, and a third fixing member (not shown in the figure) for supporting and fixing the wire connector 51 is provided on the second conductor ground 12 and / or the microstrip conductor ground 23. The connection method of the wire connector 51 with the strip conductor 13 and the microstrip conductor 21 may include welding, connection through fasteners, coupling connection and other connection methods. Those skilled in the art may set the connection method according to actual needs, and this application does not limit this.

[0135] In a possible implementation manner, the microstrip conductor ground 23 and the second conductor ground 12 are in the same plane, which may include any of the following implementation manners:

[0136] The microstrip conductor ground 23 and the second conductor ground 12 may be an integral structure (eg Figure 8A-8C As shown in FIG. 1 , the processing and manufacturing of the signal transmission structure is facilitated, and the manufacturing process is simplified. In addition, while the microstrip conductor ground 23 and the second conductor ground 12 are an integrated structure, the size of the microstrip conductor ground 23 meets the size requirements of the microstrip line, and the size of the second conductor ground 12 meets the size requirements of the strip line.

[0137] The microstrip conductor ground 23 and the second conductor ground 12 may have different structures, but in the area where the strip conductor 13 and the microstrip conductor 21 are connected, the microstrip conductor ground 23 and the second conductor ground 12 are fixedly connected together.

[0138] The material selection and size setting of the second fixing member and the third fixing member may refer to the setting of the first fixing member mentioned above, and will not be described in detail here.

[0139] Through the above method, a microstrip line and a strip line with air as a medium are provided, which can reduce the signal loss in the microstrip line and the strip line. In addition, since air is used as the medium of the microstrip line, it is not necessary to perform operations such as manufacturing metallized holes required for the connection of the strip line medium in the process of connecting the strip line with the microstrip line, which simplifies the manufacturing process of connecting the strip line with the microstrip line. In addition, since the conductors of the strip line and the microstrip line are connected in the same plane, the strip line and the microstrip line are adjusted to the same or similar plane, which simplifies the switching of the microstrip line and the strip line, facilitates the integration of the microstrip line and the strip line, and saves the height space occupied after the integration.
