Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a radiating antenna, cockpit main control equipment, and intelligent cockpit. Background Technology

[0002] Antennas, as devices for effectively transmitting and receiving electromagnetic wave signals, are an indispensable part of wireless communication. With the rapid development of autonomous driving technology and the Internet of Things, the functional requirements for wireless communication in the automotive field are increasing, and the demand for high-speed, low-latency wireless communication is growing, which in turn places higher demands on antenna performance.

[0003] However, in the automotive field, to meet the EMC (Electromagnetic Compatibility) requirements of the motherboard and the heat dissipation needs of the modules and chips on the motherboard, most products in the current smart cockpit adopt a fully metal-encased structure with many internal shielding covers. This metallic environment has a significant impact on antenna performance. Because antennas are highly sensitive to their surrounding environment, the performance of antennas provided by related technologies in the cockpit environment is difficult to meet the requirements of wireless communication. Utility Model Content

[0004] This application provides a radiating antenna, cockpit main control equipment, and intelligent cockpit, which solves the problem that antenna performance in related technologies is difficult to meet the requirements of the cockpit environment for wireless communication quality. The impedance matching of the radiating antenna provided by this solution can effectively improve the bandwidth and radiation efficiency of the resonant frequency, which helps to stabilize the standing wave performance and thus improve the antenna performance.

[0005] In a first aspect, this application provides a radiating antenna, which includes a substrate, a first radiating element and a second radiating element, wherein the first radiating element and the second radiating element are disposed on the same side of the substrate.

[0006] The first radiating unit includes a main body, a first radiating structure, and a second radiating structure. The main body is provided with a feed point area for connecting external devices. The first radiating structure and the second radiating structure are respectively connected to the two sides of the main body. A first gap area is formed between the first radiating structure and the main body so that the end of the first radiating structure is suspended and faces the main body. A second gap area is formed between the second radiating structure and the main body so that the end of the second radiating structure is suspended and faces the main body. The second radiating unit is grounded and spaced apart from the first radiating unit. The second radiating unit includes multiple spaced extensions, all of which face the first radiating unit.

[0007] The radiating antenna uses spaced radiating elements as radiating sheets and grounding branches, and forms corresponding gap regions on the first radiating element to achieve good antenna impedance matching and improve the radiation efficiency of the radiating antenna, thereby improving antenna performance and enabling it to adapt to the cockpit environment and meet wireless communication requirements.

[0008] In one embodiment, the first radiating structure includes a first radiating segment, a second radiating segment, and a third radiating segment connected in sequence. The first radiating segment is perpendicular to the main body, the second radiating segment is perpendicular to the first radiating segment, and the third radiating segment is perpendicular to the second radiating segment. The end of the third radiating segment is suspended and faces the main body to form a first gap region between the third radiating segment and the first radiating segment. The radiating antenna of this solution forms a first gap region on one side of the first radiating element through the first radiating structure, which facilitates the formation of an asymmetric dipole, thereby effectively improving the antenna performance.

[0009] In one embodiment, the second radiating structure includes a fourth radiating segment, a fifth radiating segment, and a sixth radiating segment connected in sequence; the fourth radiating segment is perpendicular to the main body, the fifth radiating segment is perpendicular to the fourth radiating segment, and the sixth radiating segment is perpendicular to the fifth radiating segment. The end of the sixth radiating segment is suspended and faces the main body to form a second gap region between the sixth radiating segment and the fourth radiating segment. The radiating antenna of this solution forms a second gap region on the other side of the first radiating element through the second radiating structure, which facilitates the formation of an asymmetric dipole, thereby effectively improving the antenna performance.

[0010] In one embodiment, the width of the first gap region is equal to the width of the second gap region, and the length of the first gap region is less than the length of the second gap region. By setting different lengths, the first gap region 101 and the second gap region 102 form regions of different sizes, thereby enabling the radiating antenna to effectively form an asymmetric dipole, thus improving antenna performance.

[0011] In one embodiment, in a first direction of the substrate, the dimensions of the first radiating structure and the second radiating structure are the same and both larger than the dimensions of the main body; in a second direction of the substrate, the first spacing between the end of the first radiating structure and the main body and the second spacing between the end of the second radiating structure and the main body are equal, and the second direction is perpendicular to the first direction. This radiating antenna design, by having the ends of the first and second radiating structures extend beyond the main body (i.e., the first and second radiating structures are not flush with the main body), shifts the antenna's resonant frequency towards a higher frequency and further improves antenna performance, resulting in lower input return loss.

[0012] In one embodiment, the extensions on the second radiating element are spaced at the same interval, and each extension extends outward by the same distance. In this scheme, the grounded second radiating element can act as a tuning impedance, which helps improve antenna performance, resulting in a lower value for the S11 parameter, thus reducing the input return loss of the radiating antenna and improving antenna performance.

[0013] In one embodiment, the second radiating element is provided with a grounding region to ground itself, and the grounding region and the feed point region are arranged in the same direction. The radiating antenna connects the inner and outer conductors of the coaxial transmission line through the feed point region and the grounding region, thereby reducing signal reflection and signal transmission loss, and also blocking external electromagnetic interference from entering the feed point region, which helps to ensure the stability of the antenna signal.

[0014] Secondly, this application also provides a cockpit master control device, which includes the radiating antenna as described above. The cockpit master control device achieves impedance matching through the radiating antenna, thereby improving the bandwidth and radiation efficiency of the resonant frequency. The antenna performance is improved, thus ensuring the wireless communication quality of the cockpit master control device to meet the wireless communication requirements in the cockpit environment.

[0015] In one embodiment, the cockpit main control device further includes a main control display and a host device. The main control display includes a screen and a PCB motherboard. The PCB motherboard is located inside the screen and is used to control the working state of the screen. The PCB motherboard is connected to the host device. The main control display is wrapped with a plastic shell around the PCB motherboard and the inside of the screen. A radiating antenna is built into the main control display and is located in the target area inside the screen. The radiating antenna is connected to the PCB motherboard through a coaxial transmission line. The target area is the area on the inside of the screen that corresponds to the edge band of the BM area on the outside of the screen.

[0016] The cockpit main control equipment integrates the radiating antenna into the main control display, which provides a better clearance environment for the radiating antenna while ensuring its good omnidirectional radiation, further improving antenna performance and facilitating the application of the radiating antenna in the cockpit environment.

[0017] Thirdly, this application also provides an intelligent cockpit, which includes the cockpit main control equipment provided in the above aspects. Attached Figure Description

[0026] Antennas, as devices for effectively transmitting and receiving electromagnetic wave signals, are an indispensable part of wireless communication. With the rapid development of autonomous driving technology and the Internet of Things, the functional requirements for wireless communication in the automotive field are increasing, and the demand for high-speed, low-latency wireless communication is growing, which in turn places higher demands on antenna performance.

[0027] In the automotive field, related technologies typically involve externally mounted antennas, such as shark fin antennas on the vehicle's exterior or roof, or antennas encapsulated in plastic boxes and placed on the center console. However, with the development of intelligent cockpits, automakers, influenced by factors such as cost and product design philosophy, are increasingly favoring integrated antenna solutions. However, in the automotive field, to meet the EMC standards of the motherboard and the heat dissipation requirements of modules and chips on the motherboard, most products in current intelligent cockpits utilize fully metal-encased structures with numerous internal shielding covers. This metallic environment significantly impacts antenna performance, interfering with wireless communication. Because antennas are highly sensitive to their surrounding environment, the antenna performance of related technologies in the intelligent cockpit environment struggles to meet wireless communication requirements.

[0028] To address this, this application provides a radiating antenna whose performance can be improved by adjusting the antenna's radiating structure, thereby providing gain and directional performance to meet wireless communication requirements, and allowing the radiating antenna to adapt to the metallic environment of the cockpit. In one embodiment, the radiating antenna includes a substrate, a first radiating element, and a second radiating element, which are disposed on the same side of the substrate. Optionally, the substrate can be a PCB (Printed Circuit Board) material, such as FR-4 material or high-frequency material. FR-4 material uses epoxy resin as a substrate and is used as a high-performance circuit board due to its good electrical insulation, heat resistance, and mechanical strength; high-frequency material is made of PTFE (polytetrafluoroethylene) to serve as a high-frequency circuit board.

[0029] Specifically, the first radiating element includes a main body, a first radiating structure, and a second radiating structure. The main body is provided with a feed point area for connecting external devices. It is conceivable that this feed point area serves as the physical connection point between the radiating antenna and external devices (such as connectors on cables, transmission lines, etc., which act as feed lines), and it can be used to convert and transmit electromagnetic wave signals.

[0030] Furthermore, the first and second radiating structures are respectively connected to both sides of the main body. For example, the first radiating structure is located on the left side of the main body, and the second radiating structure is located on the right side of the main body. A first gap region is formed between the first radiating structure and the main body, so that the end of the first radiating structure is suspended and faces the main body. A second gap region is formed between the second radiating structure and the main body, so that the end of the second radiating structure is suspended and faces the main body. The radiating antenna forms the first and second gap regions as described above on both sides of the main body through the first and second radiating structures. This is beneficial for antenna miniaturization and also enables series resonance characteristics, thereby improving the antenna's radiation efficiency. Moreover, the second radiating element, as the grounded part of the radiating antenna, is grounded and spaced apart from the first radiating element. The second radiating element includes multiple spaced extensions, all of which face the first radiating element. It is conceivable that there are corresponding recessed regions between different extensions, which can be used to tune the impedance to enhance antenna performance and give the radiating antenna better input return loss.

[0031] As can be seen from the above scheme, the radiating antenna uses a first radiating element and a second radiating element arranged at intervals to serve as a radiating sheet and a grounding branch, respectively, and forms a corresponding gap area on the first radiating element, so that the antenna impedance is well matched and the radiation efficiency of the radiating antenna is improved, thereby improving the antenna performance and enabling it to adapt to the cockpit environment and meet the wireless communication requirements.

[0032] Figure 1 This is a schematic diagram of the structure of a radiating antenna provided in an embodiment of this application. The figure shows the planar structure of the radiating antenna, as follows. Figure 1 As shown, the radiating antenna includes a substrate 110, a first radiating element 121, and a second radiating element 122. The first radiating element 121 and the second radiating element 122 are both located on the same side of the substrate 110. Furthermore, a feed point area (shown as a dashed line in the figure) is provided on the main body of the first radiating element 121, and a grounding area (shown as a dashed line in the figure) is provided on the second radiating element 122.

[0033] The first radiating unit 121 includes a main body, a first radiating structure, and a second radiating structure. Optionally, the first radiating structure includes a first radiating segment 1211, a second radiating segment 1212, and a third radiating segment 1213 connected in sequence. The first radiating segment 1211 is connected to and perpendicular to the main body; the second radiating segment 1212 is connected to and perpendicular to the first radiating segment 1211; and the third radiating segment 1213 is connected to and perpendicular to the second radiating segment 1212. That is, the third radiating segment 1213 is parallel to the first radiating segment 1211, and the end of the third radiating segment 1213 (i.e., the end not connected to the second radiating segment 1212) is suspended. (Refer to...) Figure 1The first radiating element 121 forms a bent structure on the left side of the main body through a first radiating segment 1211, a second radiating segment 1212, and a third radiating segment 1213, and a first gap region 101 is formed between the second radiating segment and the main body. It should be noted that the aforementioned radiating segments are structurally divided and used to represent partial radiating segments on the first radiating structure. The radiating antenna of this solution forms a first gap region on one side of the first radiating element through the first radiating structure, thereby effectively improving the antenna performance.

[0034] Optionally, the second radiating structure includes a fourth radiating segment 1214, a fifth radiating segment 1215, and a sixth radiating segment 1216 connected sequentially. The fourth radiating segment 1214 is connected to and perpendicular to the main body; the fifth radiating segment 1215 is connected to and perpendicular to the fourth radiating segment 1214; and the sixth radiating segment 1216 is connected to and perpendicular to the fifth radiating segment 1215. That is, the fourth radiating segment 1214 is parallel to the sixth radiating segment 1216, and the end of the sixth radiating segment 1216 (i.e., the end not connected to the fifth radiating segment 1215) is suspended. (Refer to...) Figure 1 The first radiating element 121 forms a bent structure on the right side of the main body through the fourth radiating segment 1214, the fifth radiating segment 1215, and the sixth radiating segment 1216, and a second gap region 102 is formed between the fifth radiating segment 1215 and the main body. The radiating antenna of this solution forms a second gap region on the other side of the first radiating element through the second radiating structure, which enables the radiating antenna to effectively improve antenna performance.

[0035] The radiating antenna forms different first gap regions 101 and second gap regions 102 on both sides of the main body of the first radiating element 121 to form an asymmetric dipole. The first gap regions 101 and second gap regions 102 serve as empty areas on both sides of the main body, and no metal conductors are placed in these areas. The first gap regions 101 and second gap regions 102 are also different in size. Optionally, the width of the first gap region 101 is equal to the width of the second gap region 102, and the length of the first gap region 101 is less than the length of the second gap region 102. By setting different lengths, the first gap regions 101 and second gap regions 102 form regions of different sizes. Thus, the radiating antenna can effectively form an asymmetric dipole, thereby improving the radiation performance of the antenna. This allows the antenna of this scheme to achieve the same resonant frequency in a smaller size than other antennas using the symmetric dipole method, thereby achieving the effect of antenna miniaturization. Furthermore, a plurality of extensions 1221 are provided at intervals on the second radiating element 122, each extension 1221 facing the first radiating element 121, so as to enhance the antenna performance through the recessed area between each extension 1221, so that the radiating antenna has better input return loss.

[0036] To this end, the antenna performance of the radiating antenna was demonstrated by testing its S-parameters, radiation efficiency, and gain. The corresponding test results are as follows: Figure 2-5 As shown. Among them, Figure 2 The figure shows a schematic diagram of the S-parameters of a radiating antenna provided in one embodiment of this application. The horizontal axis corresponds to frequency in GHz; the vertical axis corresponds to the input return loss (i.e., the S11 parameter) in the S-parameters, in dB. It is worth noting that the S11 parameter measures the impedance matching degree between the antenna and the feed line. A smaller value indicates greater return loss, meaning less reflection and higher transmission efficiency. The S11 parameter of the antenna is generally required to be less than -10 dB in the operating frequency band. Figure 2 The antenna performance of the radiating antenna of this application can be determined. Within the resonant frequency range (5.15-5.85GHz) of the radiating antenna, as shown in the frequency range between points 1 and 2 in the figure, where the frequency corresponding to point 1 is 5.15GHz and the frequency corresponding to point 2 is 5.85GHz, that is, the resonant frequency is greater than or equal to 5.15GHz and less than or equal to 5.85GHz. At the frequency of 5.15GHz, the value of S11 is -14.4dB, and at the frequency of 5.85GHz, the value of S11 is -12.3dB. Based on this, it can be determined that S11 is less than -10dB within this resonant frequency range. The radiating antenna of this application has good impedance matching and high signal transmission efficiency.

[0037] Figure 3 The figure shows the efficiency waveform of a radiating antenna provided in one embodiment of this application. The horizontal axis corresponds to the frequency in GHz, and the vertical axis corresponds to the efficiency value (expressed in decimal form). L1 corresponds to the radiation efficiency of the radiating antenna, and L2 corresponds to the total efficiency of the radiating antenna. In the entire resonant frequency range, the overall efficiency of the radiating antenna in this solution is greater than 0.7, that is, the overall efficiency reaches more than 70%. The radiating antenna has excellent performance and can effectively meet the performance requirements of the equipment.

[0038] Figure 4 The figure shows the 3D radiation pattern of a radiating antenna in free space according to an embodiment of this application. The radiating antenna of this solution has good radiation directional performance in the upper half of the antenna. Figure 5This diagram illustrates the average gain of a radiating antenna within a preset elevation angle range, as provided in an embodiment of this application. The horizontal axis represents frequency in GHz, and the vertical axis represents the average gain value in dBi. This preset elevation angle range is relevant to applications in a cockpit environment, allowing communication quality to be determined by detecting the gain within this range. It should be noted that -0.1 dBi is used as a threshold for testing; antennas achieving this gain value can provide good communication quality within the preset elevation angle range. As shown in the figure, the average gain of the antennas is greater than -0.1 dBi within the resonant frequency range. Antennas with an average gain greater than -0.1 dBi exhibit excellent radiation performance and possess sufficient gain within the preset elevation angle range to provide better communication quality. Combined with... Figure 4 and Figure 5 The gain and directivity of the radiating antenna can adapt to different environmental conditions and can also meet the communication needs of vehicle-mounted systems and other 5G devices in the automotive field.

[0039] In one embodiment, in a first direction of the substrate, the dimensions of the first radiating structure and the second radiating structure in the first radiating unit are the same and both larger than the dimensions of the main body. In a second direction of the substrate, which is perpendicular to the first direction, the first distance between the end of the first radiating structure and the main body and the second distance between the end of the second radiating structure and the main body are equal. For example, referring to… Figure 1 As shown in the figure, the first direction is the vertical direction, that is, the direction perpendicular to the main body. In the vertical direction (corresponding to the up and down direction in the figure), the width of the first radiating structure is the same as the width of the second radiating structure, so that the third radiating segment on the first radiating structure and the sixth radiating segment on the second radiating structure are located on the same parallel line. However, the parallel line where the main body is located in the vertical direction is lower than the outermost parallel line of the third radiating segment (that is, the parallel line closest to the edge of the substrate), so that in the vertical direction, the third radiating segment and the sixth radiating segment are closer to the edge of the substrate than the main body. It should be noted that the above-mentioned parallel lines are parallel to the left and right direction. Moreover, in the horizontal direction (corresponding to the left and right direction in the figure), the first spacing corresponds to the distance between the third radiating segment and the main body, and the second spacing corresponds to the distance between the sixth radiating segment and the main body. The first spacing and the second spacing are equal, that is, the distance between the third radiating segment and the main body and the distance between the sixth radiating segment and the main body are equal.

[0040] In response, the radiating antenna of this solution extends beyond the main body by extending the ends of the first and second radiating structures beyond the main body. This means that the first and second radiating structures are not flush with the main body, which makes the resonant frequency of the antenna biased towards a higher frequency and further improves the antenna performance, resulting in lower input return loss of the radiating antenna.

[0041] Reference Figure 1In one embodiment, the plurality of extensions 1221 provided on the second radiating element 122 are arranged at the same spacing, and each extension extends outward by the same distance. It is understood that the recessed area formed between adjacent extensions is equivalent to a capacitor on the radiating antenna. Since the dimensions of each extension are the same and the spacing between each extension is the same, the equivalent capacitance is also the same. This allows the grounded second radiating element to function as a tuning impedance, which helps improve antenna performance and allows the value of parameter S11 to be lower, i.e., reducing the input return loss of the radiating antenna and resulting in better antenna performance.

[0042] Optionally, a grounding region is provided on the second radiating element for grounding, meaning the second radiating element is grounded through the grounding region. For example, the contact area on the first radiating element is connected to other devices via a coaxial transmission line, and the grounding region on the second radiating element can share a ground with the coaxial transmission line, such as by connecting the grounding outer surface of the coaxial transmission line or connecting to the grounding terminal connected to the outer surface of the coaxial transmission line through this connection area. Furthermore, the grounding region and the feed area are arranged in the same direction; for example, both the grounding region and the feed area are rectangular areas, with the central axis of the grounding region coinciding with the central axis of the feed area, so that the feed area on the first radiating element and the grounding region on the second radiating element on the substrate are arranged in the same direction. In this way, the radiating antenna connects the inner and outer conductors of the coaxial transmission line through the arrangement of the feed area and the grounding region, thereby reducing signal reflection and signal transmission loss, and also blocking external electromagnetic interference from entering the feed area, helping to ensure the stability of the antenna signal.

[0043] This application also provides a cockpit master control device, which includes the radiating antenna provided in the above embodiments. The cockpit master control device achieves impedance matching through the radiating antenna, thereby improving the bandwidth and radiation efficiency of the resonant frequency. The antenna performance is improved, thereby ensuring the wireless communication quality of the cockpit master control device to meet the wireless communication requirements in the cockpit environment.

[0044] Figure 6The figure shows a perspective structural diagram of a cockpit main control device according to an embodiment of this application. In one embodiment, the cockpit main control device includes a radiating antenna 100, a main control display 210, and a host device 220. Specifically, the main control display 210 includes a screen 211 and a PCB motherboard 212. The PCB motherboard 212 is located inside the screen 211 and is used to control the working state of the screen 211. The inside of the screen 211 is the side that does not face the user. The main control display 210 is encased in a plastic shell 213, which covers the PCB motherboard 212 and the inside of the screen 211, meaning the PCB motherboard 212 is built into the main control display 210. The PCB motherboard 212 is connected to the host device 220, which is encased in a metal shell. The radiating antenna 100 is connected to the PCB motherboard 212 via a coaxial transmission line. Optionally, the coaxial transmission line connects the radiating antenna 100 and the PCB motherboard 212 using a flying wire. The host device, as the main control device in the cockpit, is used for data processing. Optionally, the host device includes a processor and a memory. The memory is used to store software programs, computer-executable programs, and modules. The processor executes various functional applications and data processing by running the software programs, instructions, and modules stored in the memory, such as sending signals to the PCB motherboard to control the screen's state or corresponding display content, and processing signals received and transmitted through the radiating antenna.

[0045] Furthermore, the radiating antenna 100 is integrated into the main control display 210, and is located in the target area inside the screen 211. The target area is the region on the inner side of the screen 211 corresponding to the edge of the BM (Black Matrix) area on the outer side of the screen 211. The outer side of the screen 211 is the side facing the user, and the edge of the BM area therein is also called the black border of the screen 211. From the user's perspective, the radiating antenna 100 is positioned below the black border of the screen 211, and there is no metal below the black border. The radiating antenna 100 is not encased in the metal casing of the main unit 220. Therefore, by integrating the radiating antenna 100 into the main control display 210, the cockpit main control equipment provides a better clearance environment for the radiating antenna 100 while ensuring its good omnidirectional radiation, further improving antenna performance and facilitating its application in the cockpit environment.

[0046] This application also provides a smart cockpit, which includes the cockpit main control device provided in the above embodiments. The small size of the radiating antenna facilitates integrated miniaturization design and has strong applicability, making it suitable for cockpit products. For example, in the cockpit main control device described above, it is conceivable that the cockpit main control device is equipped with the aforementioned radiating antenna, so that the smart cockpit can conduct wireless communication through the radiating antenna within the cockpit main control device. Moreover, the impedance matching of the radiating antenna can effectively improve the bandwidth and radiation efficiency of the resonant frequency, which helps to stabilize the standing wave performance, thereby improving the antenna performance and thus making the wireless communication quality better meet the wireless communication requirements in the cockpit environment.

[0047] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
