Description
Technical Field

Background
The phased array system can perform space power synthesis in a designated direction in a large airspace, can rapidly change beam direction and beam shape, and can play a great role in various application scenes such as a measurement and control system, satellite communication and the like. In practice, however, the power combining capability in different directions is closely related to the value of the angle from the normal. Therefore, achieving good scanning performance over a wide range of angles is a difficult problem for phased array systems, and designing an antenna array capable of achieving wide-angle scanning is urgent.
In order to increase the large angle scanning gain, the conventional measures are mainly to add various additional hardware. There are many ways to implement this method, including adding a focusing lens above the antenna, but at present, the lens cannot implement two-dimensional scanning; various EBG structures are added, and the theory of the EBG structures for two-dimensional scanning is immature; the tightly coupled array has a certain research result at a low frequency band, but the high frequency research is less, and meanwhile, the active standing wave of the tightly coupled array surface is seriously deteriorated, and a wide-angle matching layer needs to be additionally designed to normally work, so that the antenna profile is higher; a reconfigurable technique. The different structures of the antenna are changed by introducing a diode switch from the outside and controlling the switch, so that the antenna works in different states. This approach requires a diode switch or the like to control the switching, i.e. introduces additional control circuitry.
In summary, the current methods for improving the wide-angle scanning performance of the antenna all introduce additional hardware to different degrees, and meanwhile, the design is complex, the theory is incomplete, and the actual effect on a large-scale two-dimensional antenna array surface is very small.

The phased array system can perform space power synthesis in a designated direction in a large airspace, can rapidly change beam direction and beam shape, and can play a great role in various application scenes such as a measurement and control system, satellite communication and the like. In practice, however, the power combining capability in different directions is closely related to the value of the angle from the normal. Therefore, achieving good scanning performance over a wide range of angles is a difficult problem for phased array systems, and designing an antenna array capable of achieving wide-angle scanning is urgent.
In order to increase the large angle scanning gain, the conventional measures are mainly to add various additional hardware. There are many ways to implement this method, including adding a focusing lens above the antenna, but at present, the lens cannot implement two-dimensional scanning; various EBG structures are added. Likewise, the theory of EBG structures for two-dimensional scanning is not mature; and (4) tightly coupling the array. The tight coupling array has a certain research result in a low frequency band, but the high frequency research is less, and meanwhile, the active standing wave of the tight coupling array surface is seriously deteriorated, and a wide-angle matching layer needs to be additionally designed to normally work, so that the antenna section is higher; a reconfigurable technique. The different structures of the antenna are changed by introducing a diode switch from the outside and controlling the switch, so that the antenna works in different states. This approach requires a diode switch or the like to control the switching, i.e. introduces additional control circuitry.
In summary, the current methods for improving the wide-angle scanning performance of the antenna all introduce additional hardware to different degrees, and meanwhile, the design is complex, the theory is incomplete, and the actual effect on a large-scale two-dimensional antenna array surface is very small.
In order to solve the above problem, an embodiment of the present invention provides an antenna design method, please refer to fig. 1, and fig. 1 shows a flowchart of the antenna design method provided in the embodiment of the present invention. The antenna design method provided by the embodiment of the application comprises the following steps:
s110: and performing unit simulation on the given antenna unit, and determining the matching impedance value of the antenna unit.
If the simulation is the primary simulation, the unit simulation is carried out on the given antenna unit in any form. If not, performing unit simulation on the given antenna unit.
For example, taking the form of a patch antenna of coaxial feeding as an example, the antenna unit structure is shown in fig. 2, the antenna radiator is a metal patch, and is printed on the medium, and is contacted with the metal patch through a coaxial inner conductor passing through the dielectric plate for feeding, and the back of the medium is a metal floor of the patch, so as to avoid short circuit of the coaxial inner conductor, a larger-radius circular ring is cut out from a region concentric with the inner conductor on the metal floor, generally, the cut circular ring on the floor needs to satisfy a certain radius ratio with the inner conductor, and the radius ratio is determined by the impedance of an external coaxial interface, and is usually 50 ohms or 75 ohms.
In this embodiment, the impedance of the coaxial interface is set to 50 ohms, and then the matching impedance value of the antenna unit is 50 ohms at this time, and the antenna unit is preliminarily simulated to obtain the actual impedance value of the antenna. Generally, the antenna impedance value and the port impedance value tend to coincide at this time.
S120: array of array planes of any form and scale is carried out according to the antenna units.
And (4) carrying out array surface array of any form and scale on the antenna unit designed in the previous step. In some possible implementation manners, array plane array is performed on the antenna units, which may be triangular array or even-scale array performed on the antenna units, or rectangular array or odd-scale array performed on the antenna units, and the form of array plane of the antenna units is not limited in this embodiment.
S130: and simulating the wavefront, and determining the active impedance value of the central unit of the wavefront.
In a possible implementation manner, referring to fig. 3, fig. 3 shows a schematic diagram of an odd array arrangement of antenna units, when a wavefront is an odd array, the active impedance value of a unit located in a central row and a central column at the same time is determined as the active impedance value of a central unit of the wavefront, and the active impedance value of the central unit of the wavefront is extracted.
In a possible implementation, referring to fig. 4, fig. 4 shows a schematic diagram of an even array arrangement of antenna units, and when the array plane is an even array, the center of the array plane generally has four units: the central unit 1, the central unit 2, the central unit 3 and the central unit 4 can freely select one of the four units as a central unit for the next calculation because the impedance values of the four units in the large array are not greatly different. In this embodiment, the active impedance value of any one of the four antenna elements in the central region of the wavefront is determined as the active impedance value of the central element of the wavefront, and the active impedance value of the central element of the wavefront is extracted.
S140: and determining whether the simulation parameters of the array surface meet iteration exit conditions or not according to the active impedance value and the matching impedance value.
In this embodiment, in order to improve the large-angle scanning performance of the antenna, the active standing wave at the large scanning angle of the antenna needs to be reduced. Generally, the active standing wave of an antenna is related to the active impedance, and the closer the active impedance is to a set value, the smaller the active standing wave. Therefore, in this embodiment, whether the antenna meets the design condition is determined by using the active impedance value and the matching impedance value, and if yes, the iterative simulation is exited; and if not, performing the next iteration simulation. The scanning angle has relativity, and in the present embodiment, the scanning angle greater than or equal to 60 degrees is set as the large scanning angle.
S150: and when the simulation parameters of the array surface meet the iteration exit condition, determining the array surface as a target array.
In a possible implementation, S140: determining whether the simulation parameters of the array surface meet the iteration exit condition according to the active impedance value and the matching impedance value comprises the following steps:
and determining whether the active standing wave of the array surface under the large scanning angle is smaller than a set value or determining whether the simulation iteration times reach preset times.
When the active standing wave of the array surface under the large scanning angle is smaller than a set value, determining that the simulation parameters of the array surface meet an iteration exit condition; or when the simulation iteration times reach the preset times, determining that the simulation parameters of the array surface meet the iteration exit conditions.
The active standing wave of the antenna is related to the active impedance, and the closer the active impedance is to a set value, the smaller the active standing wave is. It is thus possible to determine whether the active standing wave of the front meets the requirements using the active impedance value and the matching impedance value. In some possible implementations, determining whether the active standing wave of the wavefront is less than a set value may include:
and determining whether the difference value between the active impedance value and the matching impedance value of the central unit of the array surface under the large scanning angle is smaller than an impedance threshold value, and determining that the active standing wave of the array surface under the large scanning angle is smaller than a set value when the difference value between the active impedance value and the matching impedance value under the large scanning angle is smaller than the impedance threshold value.
It can be understood that the active standing wave at a large scanning angle of the antenna is smaller if the active impedance value at the large scanning angle of the antenna is closer to the set matching impedance value. If the difference between the active impedance value of the antenna at the large scanning angle and the set matching impedance value is larger, the active standing wave of the antenna at the large scanning angle is larger. Therefore, when the difference value between the active impedance value and the matching impedance value under the large scanning angle of the antenna is smaller than the impedance threshold value, the active standing wave under the large scanning angle of the front surface is determined to be smaller than the set value. It should be noted that the difference between the active impedance value and the matching impedance value refers to the difference between the larger one and the smaller one of the active impedance value and the matching impedance value, which may be the difference between the active impedance value and the matching impedance value, or may be the difference between the matching impedance value and the active impedance value.
Generally, the antenna matching is considered to be good when the port standing wave is less than 2, here, the set value is set to be 2, and the situation that the active standing wave is less than 2 may not be satisfied after the program is iterated for many times, in order to save time, an iteration number judgment is added to judge whether the iteration number is greater than the set value, the larger the set value is, the longer the simulation time is, the more likely the simulation time is to approach the required standing wave value, and in a possible implementation manner, the iteration preset number is 200. And when the simulation iteration times reach the preset times, exiting the iteration.
In a possible implementation manner, please continue to refer to fig. 1, when the simulation parameter of the wavefront does not satisfy the iteration exit condition, the antenna needs to be optimized, and the antenna design method further includes:
s160-1: and determining the active impedance value of the array surface under a large scanning angle as a next iteration simulation matching impedance value.
S160-2: and adjusting the structural parameters of the antenna unit to reduce the active standing wave of the antenna unit.
If the active impedance value of the central unit of the array surface under a large scanning angle is larger than the matching impedance value, the size of the antenna unit is increased to reduce the difference value between the active impedance value and the matching impedance value, so that the active standing wave of the antenna unit is reduced;
if the active impedance value of the central unit of the array surface under the large scanning angle is smaller than the matching impedance value, the size of the antenna unit is reduced to reduce the difference value between the matching impedance value and the active impedance value, so that the active standing wave of the antenna unit is reduced.
S160-3: and performing next simulation by taking the adjusted antenna unit as a given antenna unit until the simulation parameters of the array surface meet the iteration exit condition.
In general, after three iterations, the antenna front can be substantially effective, and therefore does not take up much simulation time.
The following takes as an example a 9x9 rectangular array of wavefronts as shown in fig. 3. To illustrate the present embodiment, assume that the wavefront simulation results in complex active impedance values Z of the normal (0 ° scan angle) and the large angle scan angle (assumed to be 60 °) of the central cell, for example, assuming that the simulation results are 52.4-10.17j and 23.5+29.47j, respectively. It can be seen that in the normal direction, the normal active standing wave is 1.2 because the active impedance is close to the 50 ohms set for the previous port, while the large angle impedance deviates greatly from 50 ohms and therefore the active standing wave is 2.9.
At this time, it is determined whether the active standing wave at the required large scanning angle is smaller than a set value, and generally, the port standing wave smaller than 2 may be considered as good antenna matching, where the set value is set to 2. It is also possible that the case of an active standing wave of less than 2 is not satisfied after a large number of program iterations. In order to save time, an iteration number judgment is added to judge whether the iteration number is larger than a set value, the simulation time is longer as the set value is larger, and the simulation time is more likely to be closer to a required standing wave value, wherein the set value is assumed to be 200. And when any judgment is met, ending the simulation and outputting the antenna array surface. And when the judgment is not satisfied, taking the obtained active impedance value under the large scanning angle as the matching impedance value of the antenna unit of the next simulation. For example, in the present embodiment, the active impedance of 60 ° is 23.5+29.47j, so the impedance value of the antenna unit at the next time needs to be designed to be 23.5+29.47 j. Because the port impedance is always the impedance of the external coaxial port, in order to make the antenna impedance value a set value, the antenna structure needs to be adjusted, the selected structural parameters only have a large influence on the standing wave, and other performances of the antenna are not affected. Since the source standing wave value may change after each simulation, the above steps are continuously repeated after adjustment until the exit condition is reached. And finally outputting a array surface meeting the wide-angle scanning performance.
In order to perform the corresponding steps in the above embodiments and various possible implementations, an implementation of an antenna design apparatus is given below, please refer to fig. 5, and fig. 5 is an antenna design apparatus 300 according to a preferred embodiment of the present invention.
