[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] With the rapid development of the fifth generation mobile communication system (5G), the antennas of modern mobile communication terminals need to support both the original 4G frequency bands (700-960MHz and 1710-2690MHz) and the newly added 5G sub6G frequency bands (3200-5000MHz). The existing printed mobile communication antenna technology has limitations in covering the three frequency bands of 700-960MHz, 1710-2690MHz and 3200-5000MHz, and has not achieved ideal radiation efficiency.

[0026] like Figure 1 The figure shows the antenna structure of the related technology. Although the antenna bandwidth is widened by designing multiple branches to cover the original 4G LTE frequency band (700-960MHz and 1710-2690MHz), it has not been successfully extended to the 5Gsub6G frequency band (3200-5000MHz). This shows that the current antenna design has limitations in frequency coverage and cannot meet the higher requirements of 5G communication for antenna bandwidth.

[0027] In addition, the antenna has poor radiation efficiency at the edge frequencies. Insufficient standing wave ratio depth means that the antenna has poor impedance matching at certain frequencies, resulting in high signal reflectivity, reducing the energy radiated outward, and thus reducing the radiation efficiency of the antenna. This is a significant defect for 5G technology that pursues high-efficiency communication.

[0028] Although the multi-branch structure can achieve a certain degree of bandwidth expansion, the bandwidth performance of the antenna in the existing technology still needs to be improved. Bandwidth is an indicator to measure the frequency response range of the antenna. For modern communication antennas that need to support multiple frequency bands at the same time, wider bandwidth means better frequency coverage and stable performance at different frequencies. The bandwidth performance of antennas in the existing technology is limited and it is difficult to meet the coverage requirements of ultra-wideband frequency bands.

[0029] In summary, the existing mobile communication antennas have deficiencies in frequency coverage and radiation efficiency, especially the coverage of the 3200-5000MHz frequency band required by 5G communication and maintaining high radiation efficiency in high frequency bands, which are the main technical challenges faced by the existing technology. These problems limit the application of antennas in 5G communication systems and highlight the urgency of developing a new type of antenna that can cover ultra-wideband frequencies and maintain high efficiency.

[0030] In order to solve the technical problem of narrow antenna bandwidth in the related art, according to one aspect of an embodiment of the present invention, an antenna is provided, such as Figure 2 As shown, the antenna is printed on a dielectric substrate 1, and the antenna includes: a dielectric substrate 1, a radiation unit 2, a feeding port 4, a parasitic unit 3, a grounding port 5 and a lumped device 6, wherein the radiation unit 2, the parasitic unit 3 and the lumped device 6 are arranged on the dielectric substrate 1; the radiation unit 2 is connected to the feeding port 4, and the radiation signal is connected through the feeding port 4, wherein the radiation unit 2 is used to radiate the radiation signal within the first frequency band; the parasitic unit 3 is grounded through the grounding port 5, one end of the lumped device 6 is connected to the parasitic unit 3, and the other end of the lumped device 6 is grounded, wherein the parasitic unit 3 is used to radiate the radiation signal within the second frequency band together with the radiation unit 2; there is a first gap 7 between the radiation unit 2 and the parasitic unit 3.

[0031] The antenna provided by the present invention is printed on a dielectric substrate 1, and there is a grounded edge on the dielectric substrate 1. The basic structure of the antenna may include a radiating unit 2 and a parasitic unit 3, as well as a feeding port 4 for connecting a radiation signal to the radiating unit 2, a grounding port 5 connecting the parasitic unit 3 and the ground, and a lumped device 6 for adjusting the overall impedance of the antenna.

[0032] Among them, the feed port 4 is the starting point for the signal current to enter the antenna. Through the feed port 4, the antenna can receive the signal current from the outside, that is, the radiation signal. The radiation unit 2 is the most important radiator in the antenna. It can increase the path length of the signal current inside the radiator through various structural designs, thereby exciting multiple resonant modes. These modes cover different frequency ranges, allowing the antenna to operate in a wider frequency band. The current in the radiation unit 2 can be coupled to the parasitic unit 3 through the first gap 7. The parasitic unit 3 can excite the resonance of other frequency bands, further broadening the bandwidth of the antenna. The ground port 5 is the path for the signal current to flow back to the ground, ensuring the good grounding of the antenna, thereby optimizing the performance of the antenna. The current flows back to the ground point through the parasitic radiation branch, forming a closed current path, which is crucial to improving the radiation efficiency of the antenna. In addition, there is also a part of the clearance area on the dielectric substrate 1, that is, the part where no circuit or metal is printed around the antenna. It provides the necessary isolation for the antenna, avoids interference with other circuits or antennas, and further improves the performance of the antenna. Among them, the radiation unit 2 can radiate the radiation signal in the first frequency band, and the parasitic unit 3 can widen the width of the radiation frequency band of the antenna as a whole through the interaction with the radiation unit 2, that is, the parasitic unit 3 can realize the radiation of the radiation signal in the second frequency band together with the radiation unit 2. The first frequency band and the second frequency band can include the original 4G frequency band (700-960MHz and 1710-2690MHz) and the newly added 5G sub6G frequency band (3200-5000MHz).

[0033] Lumped devices 6 refer to components with independent electrical characteristics in a circuit, such as inductors, capacitors, etc., which can be placed independently in the circuit to achieve specific functions. In an antenna, loading a lumped inductor or capacitor can change the impedance characteristics of the antenna, making the impedance matching of the antenna more optimized at different frequencies. For example, loading a lumped inductor can increase the inductance of the antenna and reduce the Q value (quality factor) of the antenna, so that the antenna maintains good impedance matching in a wider frequency range, thereby broadening the working bandwidth of the antenna.

[0034] Moreover, the radiation efficiency of the antenna is related to the impedance of the antenna, the matching state of the antenna, and the loss of the antenna. By loading the lumped device 6, the impedance of the antenna can be adjusted, the impedance matching of the antenna can be optimized, and the loss of the antenna can be reduced, thereby improving the radiation efficiency of the antenna. In the present invention, loading the lumped inductor device not only broadens the bandwidth, but also improves the radiation efficiency of the antenna by reducing the loss and optimizing the matching state.

[0035] Through the above design, the antenna of the present invention achieves ultra-wideband frequency coverage (700-960MHz, 1710-2690MHz, 3200-5000MHz) and high radiation efficiency, with a size of only 60mm*20mm, which can be applied to various electronic products and has low cost. In addition, the antenna has strong adaptability and can be used on PCB motherboards of different sizes, showing high flexibility and practicality, solving the technical problem of narrow antenna bandwidth in related technologies, and providing an ideal antenna structure design for 5G communication terminals.

[0036] As an optional embodiment, the parasitic unit 3 includes an L-shaped radiation branch.

[0037] Optionally, the parasitic unit 3 can affect the resonance characteristics of the antenna by interacting with the radiating unit, thereby widening the bandwidth of the antenna or exciting additional resonance points to cover a wider frequency range. The L-shaped structure can effectively increase the path length of the current flow in a smaller area, which means that the signal current needs to travel a longer distance on the parasitic unit 3 before it can flow back to the ground point. This design can simulate the effect of a longer antenna while keeping the physical size of the antenna unchanged or smaller, and achieve broadband antenna in the 700-960MHz frequency band.

[0038] As an optional embodiment, a groove is provided on the L-shaped radiation branch to increase the flow path of the current on the L-shaped radiation branch.

[0039] Optionally, by providing a groove on the L-shaped radiating branch, the length of the current flowing through the L-shaped radiating branch can be increased, that is, the path of the current in the groove becomes longer. This increased length of the current flowing through the L-shaped radiating branch helps to excite additional resonance points, especially in higher frequency bands, which can broaden the bandwidth of the antenna and cover a wider frequency range. Moreover, in the circuit, the groove can be equivalent to a non-uniformly distributed capacitor or inductor, which affects the impedance of the antenna and helps the antenna maintain good impedance matching over a wider frequency range, thereby improving the bandwidth and efficiency of the antenna.

[0040] In addition, the position and size of the groove can control the resonance mode of the antenna. By setting the groove at the appropriate position on the L-shaped radiating branch, the distribution of the current can be affected, so that the antenna produces the expected resonance mode at a specific frequency, thereby achieving effective coverage of the required frequency band. Figure 2 As shown, the groove is arranged on the longer branch of the L-shaped radiating branch. In addition, the position of the groove, as well as the depth and shape of the groove can be adjusted according to actual needs.

[0041] As an optional embodiment, the first sub-slot 11 and the second sub-slot 12 are respectively present at different positions between the radiation unit 2 and the L-shaped radiation branch, wherein the first slot 7 includes the first sub-slot 11 and the second sub-slot 12 .

[0042] Optionally, there is a first slot 7 between the radiation unit 2 and the parasitic unit 3. After the radiation signal enters the radiation unit 2 through the feeding port 4, it can be coupled to the parasitic unit 3 through the first slot 7. The signal in the parasitic unit 3 can also affect the signal in the radiation unit 2 through the first slot 7. In short, the radiation unit 2 and the parasitic unit 3 can affect each other through the first slot 7. In the case where the parasitic unit 3 is an L-shaped radiation branch, the parasitic unit 3 and the radiation unit 2 can be coupled through the first sub-slot 11 and the second sub-slot 12. Figure 2 As shown, the first sub-slot 11 can achieve coupling of one side of the bent "L" shape with the radiating element 2, and the second sub-slot 12 can achieve coupling of the other side of the bent "L" shape with the radiating element 2. By coupling the parasitic element 3 and the radiating element 2 through two sub-slots, the radiation efficiency of the antenna can be improved, thereby improving the overall performance of the antenna.

[0043] As an optional embodiment, a second gap 8 exists between a first edge of the parasitic unit 3 and a grounded edge of the dielectric substrate 1 , wherein the first edge is an edge where the ground port 5 is provided.

[0044] Optionally, the gap can be equivalent to a capacitor in the circuit. When the gap is set between the first edge and the grounded edge of the dielectric substrate 1, it will introduce an equivalent capacitor between the parasitic unit 3 and the ground. This capacitor can change the impedance characteristics of the antenna, so that the antenna can achieve impedance matching in a wider frequency range, thereby widening the bandwidth of the antenna. Figure 2 As shown, the first edge may be an edge of the parasitic unit 3 where the ground port 5 is provided. It should be noted that in the actual design process, the overall structure and impedance of the antenna may be considered to adjust the position of the slot and the width of the slot to achieve better results.

[0045] As an optional embodiment, a third gap 9 exists between a second edge of the radiation unit 2 and a grounded edge of the dielectric substrate 1 , wherein the second edge is an edge where the feeding port 4 is disposed.

[0046] Optionally, a third gap 9 may be provided between the second edge and the grounded edge on the dielectric substrate 1 , wherein the second edge may be an edge of the radiation unit 2 where the feeding port 4 is provided.

[0047] As an optional embodiment, an L-shaped slot 10 is provided in the radiation unit 2 to increase the flow path of the current on the radiation unit 2 .

[0048] Optionally, in the antenna provided by the present invention, an L-shaped slot 10 may be further provided in the radiation unit 2 to increase the flow path of the current on the radiation unit 2, thereby widening the working bandwidth of the antenna and optimizing its radiation efficiency. Specifically, the L-shaped slot 10 increases the flow path of the current on the radiation unit 2, which means that the actual electrical length of the signal current on the antenna becomes longer. The increase in electrical length helps to excite additional resonance points, especially in the high frequency band, which can enable the antenna to maintain stable performance in a wider frequency range, thereby achieving ultra-wideband coverage.

[0049] As an optional embodiment, the lumped device 6 is an inductor or a capacitor. Optionally, an additional inductor or capacitor is provided on the antenna, and the impedance of the antenna as a whole can be adjusted in a more intuitive and controllable manner. In particular, when the lumped device 6 is an inductor, the inductance value can be increased, and the Q value (quality factor) of the antenna can be reduced, thereby widening the working bandwidth of the antenna. In addition, the use of lumped devices helps to improve the radiation efficiency of the antenna. For example, increasing the lumped inductor can reduce the loss in the high frequency band, and loading the lumped capacitor can improve the impedance matching of the antenna, thereby reducing the reflection loss and allowing more energy to be effectively radiated.

[0050] The use of lumped devices can achieve miniaturized antenna design. By adjusting the parameters of the lumped devices, the electrical characteristics of the antenna can be changed without increasing the physical size of the antenna, meeting the strict internal space restrictions of modern communication equipment.

[0051] As an optional embodiment, the radiation unit 2 includes a radiator with irregular edges.

[0052] Optionally, setting the edge of the antenna radiator to an irregular shape instead of a traditional rectangular shape can optimize the performance of the antenna, especially broaden the bandwidth and improve the radiation efficiency. The irregular edge can include a zigzag, a sawtooth or a wedge shape, which can provide a more complex current path than a rectangular edge, helping the antenna cover a wider frequency range.

[0053] The performance of the antenna is limited by its structure and size. The design of irregular edges can control and adjust the resonant characteristics of the antenna so that it produces resonant points at multiple frequencies. By carefully designing the shape of the edge, the antenna's response in different frequency bands such as 700-960MHz, 1710-2690MHz and 3200-5000MHz can be optimized to achieve multi-band coverage. The radiation pattern of the antenna is also affected by its structure. The design of irregular edges can change the radiation characteristics of the antenna. For example, through a specific edge shape, the radiation directivity and pattern of the antenna can be improved, unnecessary side radiation can be reduced, and the efficiency of the antenna in the main radiation direction can be improved. In addition, in a multi-antenna system, the design of irregular edges helps to reduce the coupling effect between antennas, thereby improving the performance of the antenna array and enhancing the overall performance and stability of the system.

[0054] The antenna provided by the present invention covers frequency bands such as 700-960MHz, 1710-2690MHz and 3200-5000MHz, while maintaining high radiation efficiency and miniaturization characteristics, and effectively achieves high performance of the antenna in multi-band applications by providing a more complex current path and optimized impedance characteristics.

[0055] As a specific embodiment, Figure 2 As shown, the antenna can be printed on a FR-4 dielectric substrate 1, and one side of the dielectric substrate 1 is grounded so that the antenna can be grounded. The antenna includes a radiating unit 2 that mainly radiates, and a parasitic unit 3 that assists in radiation. The signal can be input into the radiating unit 2 through a feeding port 4, then coupled to the parasitic unit 3 through a first slot 7, and finally returned through a grounding port 5. In order to broaden the bandwidth of the antenna, a lumped device 6 is also provided in the antenna, which is connected between the parasitic unit 3 and one side of the grounded dielectric substrate 1, and then grounded. The lumped device 6 can increase the inductance, reduce the Q value, broaden the antenna bandwidth, and optimize the antenna radiation efficiency.

[0056] In order to further improve the performance of the antenna, a second slot 8 and a third slot 9 are provided on the antenna. Equivalent capacitance is loaded through the slots to adjust the impedance of the antenna itself, thereby obtaining a wider bandwidth. An L-shaped slot 10 may be provided in the radiation unit 2 to increase the current flow path, increase the high-frequency current flow path of the antenna, and realize a broadband design. The shape of the radiation branches included in the parasitic unit 3 may also be set by folding, multi-branching, slotting, etc., so that the signal has current paths of different lengths, thereby exciting resonant modes of different frequencies and creating multiple resonant frequencies, thereby achieving the purpose of covering the entire 5G frequency band.

[0057] It should be noted that Figure 2Only one optional antenna structure is provided, on this basis, the position of the groove, the size of the groove, the setting position of the lumped device 6, the specific parameters of the lumped device 6, the position of the gap, the size of the gap, etc. can all be flexibly adjusted according to actual needs.

[0058] Figure 3 yes Figure 2 The schematic diagram of the standing wave ratio of the antenna shown is as follows Figure 3 As shown, the standing wave of the antenna is basically less than 3. Figure 4 yes Figure 2 A schematic diagram of the radiation efficiency of the antenna shown, Figure 4 As shown, the radiation efficiency of the antenna is greater than 70%, which can meet the general antenna performance requirements.

[0059] According to an embodiment of the present invention, an embodiment of a transmission method applied to any one of the above-mentioned antennas is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0060] The method comprises: inputting a signal to be transmitted into a radiation unit through a feeding port, wherein the signal to be transmitted flowing through the radiation unit is coupled to a parasitic unit through a first gap, and the parasitic unit and / or the radiation unit converts the signal to be transmitted into an electromagnetic wave and radiates it outward.

[0061] The transmission method proposed in the embodiment of the present invention is a signal transmission process for the antenna designed as above. First, the signal to be transmitted is input to the radiation unit through the feeding port of the antenna, wherein the feeding port is the starting point for the signal current to enter the antenna, and the signal is usually provided by a radio frequency power source, and the main function of the radiation unit is to convert the input signal current into electromagnetic waves.

[0062] The signal current inside the radiation unit is coupled to the parasitic unit through the first slot. Slot coupling is a mode of electromagnetic energy transmission. Through the slot, the signal current can cross the physical breakpoint to achieve energy transfer from one conductor to another. In the present invention, the first slot is used to partially couple the signal current of the radiation unit to the parasitic unit, and utilize the interaction between the parasitic unit and the main radiation unit to stimulate additional resonance points and broaden the bandwidth of the antenna.

[0063] The signal to be transmitted is coupled between the radiating unit and / or the parasitic unit through the gap, and is finally converted into an electromagnetic wave and radiated outward. In addition, the signal current can also be returned to the ground through the ground port of the parasitic unit. The design of the radiating unit and the parasitic unit enables it to effectively excite multiple resonance points and cover a wide frequency range, so that the antenna can operate in frequency bands such as 700-960MHz, 1710-2690MHz and 3200-5000MHz, realizing ultra-wideband communication.

[0064] Through the above process, the transmission method of the present invention can ensure that the antenna can cover a wider frequency band when receiving and transmitting signals, and improve the radiation efficiency through the joint action of slot coupling and parasitic units, and finally achieve efficient and extensive electromagnetic wave radiation. This method embodiment makes full use of the structural characteristics of the antenna, especially the design of the slot and parasitic unit, to optimize signal transmission and meet the high requirements of modern mobile communication systems for antenna performance.

For example, when applied to a terminal for controlling antenna communication, it can easily realize signal transmission in simple communication scenarios; for another example, when applied to a server, it can call on the server's rich computing resources to realize signal transmission in more complex communication scenarios.
