[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Currently, most of the existing dual-scenario phase shifters are U-shaped line with switch solutions. The U-shaped solution has limited applicable scenarios. Therefore, it is necessary to design a cavity stripline with switch solution with good amplitude flatness and good matching to meet the increasing demand for dual-scenario antennas with higher matching requirements.

[0034] Based on this, a matching method for a dual-scenario antenna and a phase shifter for a dual-scenario antenna network provided by an embodiment of the present invention can relatively conveniently match the lines of the dual-scenario antenna. At the same time, it also helps to improve the matching degree of the dual-scenario antenna.

[0035] To facilitate the understanding of this embodiment, a matching method for a dual-scenario antenna disclosed in an embodiment of the present invention will be introduced in detail first.

[0036] In a possible implementation manner, an embodiment of the present invention provides a matching method for a dual-scenario antenna. As Figure 1 shown in the flowchart of a matching method for a dual-scenario antenna, the method includes the following steps:

[0037] Step S102: Build a simulation circuit diagram of the dual-scenario antenna according to a preset application scenario;

[0038] Among them, the application scenarios in the embodiments of the present invention include a single electrical adjustment scenario and a break scenario;

[0039] In actual use, the simulation circuit diagram in the embodiments of the present invention is built in a simulation scenario. And since the application scenarios in the embodiments of the present invention include the single electrical adjustment scenario and the break scenario, the corresponding simulation circuit diagram actually also includes the simulation circuit diagrams under two scenarios. Therefore, in the following matching process, each application scenario needs to be matched separately.

[0040] Step S104: In the simulation scenario, match simulation lines for the simulation circuit diagrams under each application scenario to obtain a scenario simulation circuit diagram corresponding to the antenna mode under the application scenario;

[0041] Step S106: Generate a simulation schematic diagram of a phase shifter including a dual-scenario antenna based on the scenario simulation circuit diagram;

[0042] Among them, the simulation schematic diagram of the phase shifter in the embodiment of the present invention is used to construct a phase shifter for a dual-scenario antenna network.

[0043] In actual use, in the above step S104, it actually includes the matching processes in two scenarios: a single electrical tuning scenario and a break scenario. That is, in the single electrical tuning scenario, a scenario simulation circuit diagram of the single electrical tuning scenario antenna mode is matched through simulation, and in the break scenario, a scenario simulation circuit diagram of the break scenario antenna mode is matched through simulation, and then the final simulation schematic diagram of the phase shifter is obtained.

[0044] Therefore, the matching method for a dual-scenario antenna provided by the embodiment of the present invention can build a simulation circuit diagram of the dual-scenario antenna according to a preset application scenario in the matching method of the dual-scenario antenna; and in the simulation scenario, match simulation lines for the simulation circuit diagrams in each application scenario to obtain a scenario simulation circuit diagram corresponding to the antenna mode in the application scenario; and then generate a simulation schematic diagram of a phase shifter including a dual-scenario antenna based on the scenario simulation circuit diagram, and this simulation schematic diagram of the phase shifter is used to construct a phase shifter for a dual-scenario antenna network. Since in the simulation process, simulation lines can be matched for the simulation circuit diagrams in each application scenario and meet the antenna mode in that application scenario, it helps to obtain a dual-scenario antenna with better matching degree to meet the application requirements of the dual-scenario antenna.

[0045] In actual use, to facilitate the construction of the simulation circuit diagram of the dual-scenario antenna, generally, it can be realized with the help of corresponding simulation software. For example, AWR software. This AWR software is a professional electronic design automation software tool focusing on the design and simulation of radio frequency, microwave, and millimeter-wave circuits. Therefore, based on the simulation software, when building the simulation circuit diagram, the simulation software can be started, and the simulation interface can be displayed through the graphical user interface; then the simulation circuit diagram of the dual-scenario antenna is built in the simulation interface.

[0046] For example, taking the application scenarios in the embodiment of the present invention including a single electrical tuning scenario and a break scenario as an example, the corresponding simulation circuit diagram should also be able to implement the corresponding two antenna modes, that is, to achieve a dual-scenario with dual modes. Specifically, in the embodiment of the present invention, the simulation circuit diagram includes a main path matching line and at least one branch matching line connected to the main path matching line; one end of the main path matching line is provided with a main port, the other end is connected to at least one branch matching line, one end of the branch matching line is connected to the main path matching line, and the other end is provided with a sub-port.

[0047] For ease of understanding, Figure 2 a schematic diagram of a simulation circuit diagram is shown, as Figure 2As shown, it includes a main port 101, branch ports 102, 103, branch matching lines 104, 105, and a main path matching line 106.

[0048] Based on Figure 2 , when the branch matching lines corresponding to the two branch ports are both working, it corresponds to the single electrical tuning scenario; when one of the branch ports is disconnected, or one of the branch ports is set to an ultra-high impedance to simulate an open circuit state, it corresponds to the fracture scenario; therefore, based on Figure 2 the shown simulation circuit diagram, global variable optimization can be performed on the circuit synchronization in the two scenarios, so as to obtain the lines that are synchronously matched in the two scenarios, that is, the process of matching simulation lines for the simulation circuit diagram in each application scenario in the embodiments of the present invention, and then obtain the scenario simulation line diagram corresponding to the antenna pattern in the application scenario.

[0049] Specifically, when implemented, for the Figure 2 shown built simulation circuit diagram, it is not clear what specific lines and impedances it contains. Through the matching process in the embodiments of the present invention, the antenna network included in each main path matching line and branch matching line can be obtained, and then the scenario simulation line diagram corresponding to the antenna pattern in the corresponding application scenario can be obtained.

[0050] Specifically, in the embodiments of the present invention, when matching the simulation lines, it is also carried out in the simulation scenario, that is, in the simulation scenario, the main path matching lines and branch matching lines corresponding to the single electrical tuning scenario and the fracture scenario are respectively matched; then the parameters of the main path matching lines and branch matching lines are optimized to obtain the scenario simulation line diagram corresponding to the antenna pattern in the corresponding application scenario.

[0051] Specifically, in the single electrical tuning scenario, the impedances respectively corresponding to the main port and the branch ports are configured, as well as the antenna networks respectively corresponding to the main path matching line and the branch matching lines; among them, in the single electrical tuning scenario, the impedance of each branch port is the same; and, the antenna network obtained by matching at this time includes the antenna lines respectively included in the main path matching line and the branch matching lines, and the switch line connecting the branch matching line and the main path matching line; among them, in this single electrical tuning scenario, the above switch line is in a direct connection state.

[0052] Further, in the fracture scenario, the impedances respectively corresponding to the main port and the branch port are configured, as well as the antenna networks respectively corresponding to the main path matching line and the branch matching lines; among them, in the fracture scenario, the impedance of one of the branch ports is the open circuit impedance; and, the antenna network includes the antenna lines respectively included in the main path matching line and the branch matching lines, and the switch line connecting the branch matching line and the main path matching line; among them, in the fracture scenario, the switch line is in a fracture state.

[0053] When configuring the antenna networks corresponding to the main path matching line and the branch matching line respectively, the parameters of the simulation units included in the main path matching line and the branch matching line can be configured in a simulation scenario. Herein, the simulation unit is used to represent a preset impedance. For example, in simulation software, a simulation unit can be represented by a graphic such as a square. The simulation unit can represent a matching section, a phase shift section, etc. of an actual line. Moreover, the parameters of the simulation unit include at least one of the following: the number, length, width, etc. of the simulation unit. For example, a simulation unit can represent a strip line. By configuring the number of strip lines, the length and width of each strip line, the matching of the main path matching line and the branch matching line can be achieved. Then, through optimizing the parameters, it can be known whether the currently matched main path matching line and branch matching line meet the requirements.

[0054] Specifically, during the optimization process, a simulation curve can be generated based on the parameters of the main path matching line and the branch matching line until the simulation curve meets the preset curve parameters, and a scene simulation circuit diagram corresponding to the antenna pattern in the application scenario is obtained.

[0055] Among them, the simulation curve in the embodiments of the present invention includes at least one of the following curves: the amplitude curve, the standing wave curve, and the Smith chart corresponding to each application scenario.

[0056] For ease of understanding, Figure 3 a schematic diagram of the matching process of an antenna line is shown. Among them, Figure 3 in (a) represents the matching process of a single electrical tuning scenario, and (b) represents the matching process of a break scenario. Among them, Figure 3 in, a square is used to represent a simulation unit, that is, a strip line. By configuring the parameters of each square, such as "W", "L", etc., the width and length of the strip line represented by the corresponding simulation unit can be configured, and each simulation unit can be configured.

[0057] Furthermore, in Figure 3Among them, Port1 represents the main port, and Port2 and Port3 represent the branch ports. In (a), the impedance of the main port Port1 is set to a preset impedance, such as 50 Ω. At the same time, the impedances of the branch ports are set to Z1 Ω and Z2 Ω respectively, so that the impedances of the two branch ports are the same, thereby representing the above single electrically tunable scenario. For example, in Figure (b), the impedance of the main port Port1 can also be set to a preset impedance, such as 50 Ω, and the impedance of one of the branch ports, such as Port3, is set to 10,000 Ω, that is, the open circuit impedance is represented by a large impedance, and the above fracture scenario can be obtained. Then, in the two scenarios of (a) and (b), the corresponding circuits are optimized synchronously, and the antenna parameters in the two scenarios can be obtained, such as the port impedance values and line distributions with good S parameters, that is, the impedances of the main port and the branch ports, as well as the number, length, width, etc. of the strip lines, thereby obtaining a scenario simulation circuit diagram that meets the requirements.

[0058] Furthermore, when optimizing the parameters, the above simulation curves can be used. Specifically, the simulation curves under each antenna parameter can be directly generated based on the above simulation software, and then the antenna parameters can be continuously optimized based on the simulation graphics until the final parameters are obtained.

[0059] Moreover, when generating the simulation curves, the above simulation software can also be used, such as AWR software, or HFSS (High Frequency Structural Simulator) software, etc. Among them, HFSS software is a high-frequency structure simulation software that can quickly and accurately solve 3D electromagnetic problems, such as calculating S parameters, resonant frequencies, and corresponding fields, etc. The specific generation process of the simulation curves can be set based on the actual usage situation, and the embodiments of the present invention do not limit this.

[0060] Furthermore, for the sake of understanding, Figure 4 and Figure 5 respectively show the schematic diagrams of the simulation curves. Specifically, Figure 4 and Figure 5 are respectively Figure 3 the phase shift mode amplitude curve and the fracture mode amplitude curve obtained after simulation by the AWR software in the two scenarios in Figure 4 and Figure 5 It can be seen from

[0061] Furthermore, Figure 6 and Figure 7 respectively show the schematic diagrams of another simulation curve. Specifically, Figure 6 and Figure 7 are respectively the phase shift mode standing wave curve and the fracture mode standing wave curve. It can be seen from Figure 6and Figure 7 It can be seen that the standing waves in both scenarios are < 1.25;

[0062] Furthermore, Figure 8 Another schematic diagram of the simulation curve is also shown, where, Figure 8 It is the standing wave curve obtained by performing a field simulation on the circuit of the overall phase shifter simulation schematic diagram built under the HFSS software. Among them, Figure 8 in it, the solid line represents the phase shift mode, and the dashed line represents the break mode. From Figure 8 it can be seen that the standing waves of the three angles in the phase shift mode and the break mode are both < 1.25.

[0063] Furthermore, Figure 9 Another schematic diagram of the simulation curve is also shown, where, Figure 9 It is the amplitude curve obtained by the HFSS software. Similarly, the solid line represents the phase shift mode, and the dashed line represents the break mode. From Figure 9 it can be seen that in the phase shift mode, the amplitude fluctuations of the three angles are within ±1 dB, and in the break mode, the amplitude at the break is < -21 dB.

[0064] Furthermore, Figure 10 It is a Smith chart obtained by the HFSS software simulation. The solid line is the three angles of the phase shift mode, and the dashed line is the break mode. From Figure 10 it can be seen that the overall is relatively convergent.

[0065] By the above method of optimizing parameters by combining simulation curves, a better schematic diagram of the scenario simulation circuit can be obtained.

[0066] Furthermore, the schematic diagram of the scenario simulation circuit obtained at this time can be used to generate a schematic diagram of the phase shifter simulation including a dual-scenario antenna. Specifically, a schematic diagram of the phase shifter simulation including a dual-scenario antenna can be generated based on the main path matching circuit, the branch matching circuit, and the switch circuit; among them, in the schematic diagram of the phase shifter simulation of the dual-scenario antenna, one branch matching circuit is connected to the main path matching circuit, and the other branch matching circuit is connected to the main path matching circuit through the switch circuit; and, in the single electrical tuning scenario, the switch circuit is in a direct connection state, and in the break scenario, the switch circuit is in an open state.

[0067] Furthermore, for the sake of easy understanding, Figure 11 a schematic diagram of the phase shifter simulation of a dual-scenario antenna is shown, as Figure 11 shown, including the main port 101, the branch port 102, and the branch port 103. Furthermore, in the single electrical tuning scenario, the branch ports 102 and 103 correspond to two sub-feed ports; in the break scenario, the branch port 102 is in a direct connection state, the branch port 103 is configured in a break state, and there is no additional power consumption.

[0068] Furthermore, Figure 11It includes a main path matching circuit 106, and two branch matching circuits. Specifically, one of the branch matching circuits includes matching segments 421 and 423 corresponding to the branch port 102, and a phase shifter segment 422; the other branch matching circuit includes matching segments 431 and 433 corresponding to the branch port 103, and a phase shifter segment 432. Among them, the above-mentioned phase shifter segments are arranged in the middle of the two matching segments, and Figure 11 It further includes a switch circuit 441. In the single electrical tuning scenario, the switch circuit 441 is placed in parallel and is coupled to the two branch matching circuits with a certain gap; in the broken scenario, the switch circuit 441 rotates and has no coupling with one side circuit, corresponding to the broken state 442.

[0069] In actual use, the above-mentioned Figure 11 Each of the matching segments in it is obtained through the aforementioned matching process. For example, each matching segment includes several strip lines, and the length, width, etc. of each strip line.

[0070] Therefore, the matching method of the dual-scenario antenna provided by the embodiment of the present invention can divide the matching process of the phase shifter of the dual-mode dual-scenario antenna into two circuit synchronous matching processes with the help of simulation software such as AWR software. Circuit one is the single electrical tuning scenario where the branch matching circuits are connected in parallel, and circuit two is the broken scenario where only one branch matching circuit is connected to the main path matching circuit and the other branch matching circuit is open. On this basis, with the help of simulation software such as HFSS, the circuit optimized by AWR can be built for further simulation optimization to obtain the final circuit.

[0071] Moreover, the efficiency of the above-mentioned simulation process is high, the matching effect is good, the amplitude flatness is good, and it is applicable to the dual-scenario antenna mode, which helps to realize a fast simulation scheme with excellent performance for cavity phase shift and broken dual modes.

[0072] Furthermore, the embodiment of the present invention also provides a dual-scenario antenna network phase shifter, and the dual-scenario antenna network phase shifter is constructed based on the phase shifter simulation schematic diagram; among them, the phase shifter simulation schematic diagram is obtained based on the matching method of the aforementioned dual-scenario antenna.
