Description

Technical Field

[0001] This disclosure relates to the field of antennas, and more particularly to a detection antenna array based on a planar magnetoelectric resonator and a method for electromagnetic wave reflection. Background Technology

[0002] Reflector array antennas are a new type of array antenna that combines the characteristics of parabolic antennas and traditional microstrip array antennas, and have been widely used in radar detection and communication fields. A reflector array antenna typically consists of a feed and multiple similar reflector elements. The electromagnetic waves emitted by the feed are reflected by the reflector elements and have different phase differences, thus forming a specific aperture distribution. Therefore, the performance of the reflector elements largely determines the performance of the entire array.

[0003] Due to their unique resonant properties, magnetoelectric antennas have been introduced as a type of reflective array antenna element. However, existing magnetoelectric reflective elements are usually composed of magnetoelectric dipoles, and magnetic resonance requires the use of metal vias and a ground plane. The magnetic resonance performance is largely limited by the thickness of the dielectric material; when the dielectric thickness decreases, the magnetic resonance state may deteriorate sharply or even disappear.

[0004] Therefore, how to make the magnetic resonance performance unaffected by the thickness of the medium and improve the array performance has become an important research problem. Summary of the Invention

[0005] In view of this, the purpose of this disclosure is to propose a detection antenna array based on a planar magnetoelectric resonator and an electromagnetic wave reflection method to solve or partially solve the above problems.

[0006] To achieve the above objectives, a first aspect of this disclosure provides a detection antenna array based on a planar magnetoelectric resonator, comprising:

[0007] At least one planar magnetoelectric resonator, each of the planar magnetoelectric resonators comprising a complete metal ring and a first open metal ring, the first open metal ring being connected to the complete metal ring;

[0008] A dielectric substrate is disposed below the planar magnetoelectric resonator;

[0009] A metal plane is disposed below the dielectric substrate.

[0010] Based on the same inventive concept, a second aspect of this disclosure proposes an electromagnetic wave reflection method applied to the aforementioned detection antenna array, comprising:

[0011] Receive incident electromagnetic waves, wherein the incident electromagnetic waves include a first incident electromagnetic wave incident on the planar magnetoelectric resonator and a second incident electromagnetic wave incident on the dielectric substrate.

[0012] The first incident electromagnetic wave in the horizontal direction of the planar magnetoelectric resonator is coupled using a first open metal ring to generate a first resonant current.

[0013] The first incident electromagnetic wave in the vertical direction of the planar magnetoelectric resonator is coupled using a complete metal ring and a first open metal ring to generate a second resonant current.

[0014] A resonant electromagnetic wave is obtained based on the first resonant current and the second resonant current;

[0015] The second incident electromagnetic wave and the resonant electromagnetic wave are transmitted to the metal plane via the dielectric substrate;

[0016] The second incident electromagnetic wave and the resonant electromagnetic wave are reflected and emitted through the metal plane.

[0017] Based on the same inventive concept, a third aspect of this disclosure provides a non-transitory computer-readable storage medium that stores computer instructions for causing a computer to perform the method described above.

[0018] As can be seen from the above, this disclosure proposes a detection antenna array and electromagnetic wave reflection method based on a planar magnetoelectric resonator. A first incident electromagnetic wave in the horizontal direction of the planar magnetoelectric resonator is coupled through a first open metal ring in at least one planar magnetoelectric resonator to generate a first resonant current, providing magnetic resonance and ensuring stable generation of magnetic resonance. A second resonant current is generated by coupling the first incident electromagnetic wave in the vertical direction of the planar magnetoelectric resonator through a complete metal ring in at least one planar magnetoelectric resonator, providing electrical resonance. The planar magnetoelectric resonator adopts a purely planar structure, so that the performance of the detection antenna array is no longer limited by the thickness of the dielectric material, ensuring stable generation of magnetic resonance.

[0031] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains.

[0033] The following are definitions of terms used in this disclosure:

[0034] ME antenna: Magnetoelectric (ME) antenna.

[0035] Based on the above description, this embodiment proposes a detection antenna array based on a planar magnetoelectric resonator, such as... Figure 1 As shown, it includes:

[0036] At least one planar magnetoelectric resonator 101, such as Figure 2 As shown, each of the planar magnetoelectric resonators 101 includes a complete metal ring 1011 and a first open metal ring 1012, wherein the first open metal ring 1012 is intersected and connected to the complete metal ring 1011.

[0037] A dielectric substrate 102 is disposed below the planar magnetoelectric resonator 101;

[0038] A metal plane 103 is disposed below the dielectric substrate 102.

[0039] In a specific implementation, the probe antenna array 100 includes, from top to bottom, at least one planar magnetoelectric resonator 101, a dielectric substrate 102, and a metal plane 103 stacked sequentially. Each planar magnetoelectric resonator 101 includes a complete metal ring 1011 and a first open metal ring 1012. The complete metal ring 1011 is connected to the first open metal ring 1012, wherein the connection between the complete metal ring 1011 and the first open metal ring 1012 is such that the first open metal ring is connected to the complete metal ring at any position. Both the complete open ring 1011 and the first open metal ring 1012 are rings formed of metal material.

[0040] Figure 1 and Figure 2 In the diagram, the x-direction is the horizontal direction of the planar magnetoelectric resonator 101, the y-direction is the vertical direction of the planar magnetoelectric resonator 101, and the z-direction is the direction of the metal plane-dielectric substrate-planar magnetoelectric resonator. Figure 1 The vertical direction of the detection antenna array 100.

[0041] The planar magnetoelectric resonator 101 receives incident electromagnetic waves, and the horizontal incident electromagnetic waves are coupled to the planar magnetoelectric resonator 101 using the first open metal ring 1012. Figure 2 The electromagnetic wave polarized in the x-direction, as shown, generates the first resonant current.

[0042] The vertical incident electromagnetic wave of the planar magnetoelectric resonator 101 is coupled using a complete metal ring 1011 and a first open metal ring 1012. Figure 2 The electromagnetic wave polarized in the y-direction, as shown, generates a second resonant current.

[0043] Based on the first resonant current and the second resonant current, a resonant electromagnetic wave is obtained, and the planar magnetoelectric resonator 101 transmits the resonant electromagnetic wave to the dielectric substrate 102.

[0044] The dielectric substrate 102 receives the resonant electromagnetic wave, sends the resonant electromagnetic wave to the metal plane 103, and reflects the resonant electromagnetic wave out through the metal plane 103.

[0045] In some embodiments, the first open metal ring 1012 is provided with a first opening 10121;

[0046] In a specific implementation, the diagonal position of the first opening 10121 is connected to the complete metal ring 1012. That is, in this embodiment of the application, the connection between the first opening metal ring 1012 and the complete metal ring 1011 is preferably such that the portion of the first opening metal ring 1012 corresponding to the diagonal position of the first opening on the first opening metal ring 1012 is connected to the complete metal ring 1011.

[0047] The above scheme uses a pure planar structure for the planar resonant magnetoelectric device, which makes the performance of the detection antenna array no longer limited by the thickness of the medium, thus ensuring the stable generation of magnetic resonance.

[0048] In some embodiments, each of the planar magnetoelectric resonators 101 further includes a second open metal ring 1013.

[0049] The second open metal ring 1013 is disposed at a concentric position with the first open metal ring 1012, and the size of the second open metal ring 1013 is smaller than the size of the first open metal ring 1012.

[0050] In a specific implementation, the planar magnetoelectric resonator 101 is further provided with a second open metal ring 1013, which is concentrically arranged with the first open metal ring 1012. The second open metal ring 1013 is a ring made of metal material, and its size is set according to a preset ratio with respect to the size of the first open metal ring 1012, wherein the preset ratio ranges from (0,1).

[0051] When the polarization type of the incident electromagnetic wave is circular polarization, the second open metal ring 1013 represents the horizontal incident electromagnetic wave of the planar magnetoelectric resonator 101, i.e. Figure 2 The electromagnetic wave polarized in the x-direction provides an additional high-frequency resonant point, thereby extending the bandwidth of the probe antenna array 100 to higher frequencies, increasing the relative operating bandwidth of the probe antenna array 100, and improving its operating performance.

[0052] For example, such as Figure 3a and Figure 3b The relative operating bandwidth refers to the ratio of the absolute bandwidth to the center frequency when the cross-polarization amplitude level is less than -15dB. The absolute bandwidth is the frequency range that satisfies the requirement that the cross-polarization amplitude level is less than -15dB. The amplitude level is the amplitude of the reflection coefficient, which is the ratio of the amplitude of the reflected electromagnetic wave to the amplitude of the incident electromagnetic wave.

[0053] If the frequency range corresponding to the cross-polarization amplitude level being less than -15dB is 12GHz to 20GHz, then the relative operating bandwidth is calculated as (20-12) / 16.

[0054] When the polarization type of the incident electromagnetic wave is circular polarization, Figure 3a When the second open metal ring 1013 is not provided for the planar magnetoelectric resonator, the reflection coefficient of the detection antenna array 100 is... Figure 3b The reflection coefficient of the probe antenna array 100 is compared when a second open metal ring 1013 is provided for the planar magnetoelectric resonator. Figure 3a and Figure 3b ,calculate Figure 3a The relative working bandwidth is 35%, calculated Figure 3a The relative operating bandwidth is 64.2%, meaning that by setting a second open metal ring, the relative operating bandwidth of the probe antenna array 100 is increased from 35% to 64.2% when a circularly polarized incident electromagnetic wave is incident.

[0055] By employing the above scheme, when a circularly polarized incident electromagnetic wave is incident, the relative operating bandwidth of the detection antenna array 100 is increased by utilizing the second open metal ring, thereby improving its operating performance.

[0056] In some embodiments, the opening direction of the second open metal ring 1013 is consistent with the opening direction of the first open metal ring 1012.

[0057] In specific implementation, the opening direction of the second open metal ring 1013 can be any direction. In this embodiment, it is preferable to keep the opening direction consistent with that of the first open metal ring 1012.

[0058] In some embodiments, the shape of the complete metal ring 1011 and the shape of the first open metal ring 1012 are rhomboid.

[0059] In specific implementation, the shape of the complete metal ring 1011 and the shape of the first open metal ring 1012 can be at least one of the following: circular, elliptical, rhomboid, rectangular, triangular, or pentagonal. The shapes of the complete metal ring 1011 and the first open metal ring 1012 can be different. In this embodiment, the shapes of the complete metal ring 1011 and the first open metal ring 1012 are preferably the same, both being rhomboid.

[0060] When the complete metal ring 1011 and the first open metal ring 1012 are rectangular, the first open metal ring and the complete metal ring can be connected by a metal wire or a metal cord.

[0061] In some embodiments, the second open metal ring 1013 is rhomboid in shape.

[0062] In specific implementation, the shape of the second open metal ring 1013 can be at least one of the following: circular, elliptical, rhomboid, rectangular, triangular or pentagonal. In this embodiment, the shape of the second open metal ring 1013 is preferably rhomboid.

[0063] In some embodiments, the complete metal ring 1011, the first open metal ring 1012, and the second open metal ring 1013 are rhombuses with four interior angles of 90 degrees.

[0064] Based on the same inventive concept, corresponding to the above embodiments, this disclosure also provides an electromagnetic wave reflection method, applied to the detection antenna array described in the above embodiments, such as... Figure 4 As shown, the detection antenna array includes at least one planar magnetoelectric resonator, the planar magnetoelectric resonator comprising a complete metal ring and a first open metal ring, and the method includes:

[0065] Step 401: Receive incident electromagnetic waves, wherein the incident electromagnetic waves include a first incident electromagnetic wave incident on the planar magnetoelectric resonator and a second incident electromagnetic wave incident on the dielectric substrate.

[0066] In practice, the probe antenna array receives the incident electromagnetic waves. Because the area of ​​the planar magnetoelectric resonator is smaller than the area of ​​the dielectric substrate and the metal plane, the incident electromagnetic waves include a first incident electromagnetic wave incident on the planar magnetoelectric resonator and a second incident electromagnetic wave incident on the dielectric substrate. The first incident electromagnetic wave resonates with the planar magnetoelectric resonator and is then transmitted to the metal plane via the dielectric substrate for reflection. The second incident electromagnetic wave passes directly through the dielectric substrate to the metal plane, is reflected, and exits without passing through the planar magnetoelectric resonator.

[0067] Step 402: The first incident electromagnetic wave in the horizontal direction of the planar magnetoelectric resonator is coupled using the first open metal ring to generate the first resonant current.

[0068] In specific implementation, the first open metal ring is sensitive to the first incident electromagnetic wave in the horizontal direction of the planar magnetoelectric resonator, that is... Figure 2 The electromagnetic wave is polarized in the x-direction, as shown. When the first electromagnetic wave polarized in the horizontal direction is incident, the first open metal ring couples the first electromagnetic wave polarized in the horizontal direction, generating a first resonant current, i.e., providing magnetic resonance. The direction of the first resonant current is as follows: Figure 5 As shown.

[0069] Step 403: The first incident electromagnetic wave in the vertical direction of the planar magnetoelectric resonator is coupled using the complete metal ring and the first open metal ring to generate the second resonant current.

[0070] In specific implementation, the overall structure of the complete metal ring and the first open metal ring is sensitive to the first incident electromagnetic wave in the vertical direction of the planar magnetoelectric resonator, that is... Figure 2 The electromagnetic wave is polarized in the y-direction, as shown. When the first electromagnetic wave, polarized in the vertical direction, is incident, the overall structure of the complete metal ring and the first open metal ring couples the first electromagnetic wave, generating a second resonant current, i.e., providing electrical resonance. The direction of the second resonant current is as follows: Figure 6 As shown.

[0071] Step 404: Obtain the resonant electromagnetic wave based on the first resonant current and the second resonant current.

[0072] Step 405: The second incident electromagnetic wave and the resonant electromagnetic wave are transmitted to the metal plane via the dielectric substrate.

[0073] Step 406: The second incident electromagnetic wave and the resonant electromagnetic wave are reflected and emitted through the metal plane.

[0074] In specific implementation, a resonant electromagnetic wave is obtained based on the first resonant current and the second resonant current, and the resonant electromagnetic wave is transmitted to a dielectric substrate. The dielectric substrate receives the resonant electromagnetic wave and the second incident electromagnetic wave incident on the dielectric substrate, and transmits them to a metal plane via the dielectric substrate. The metal plane then reflects and emits the resonant electromagnetic wave and the second incident electromagnetic wave.

[0075] In some embodiments, in response to the detection antenna array comprising at least two planar magnetoelectric resonators, for each planar magnetoelectric resonator, after step 401, the method further includes:

[0076] Step 40A: Obtain the polarization type of the incident electromagnetic wave and the target reflection phase.

[0077] In specific implementation, after the planar magnetoelectric resonator receives the incident electromagnetic wave, it first determines the polarization type of the incident electromagnetic wave. The polarization type of the incident electromagnetic wave includes at least one of the following: linear polarization, circular polarization, or elliptical polarization. The circular polarization type includes at least one of the following: left-hand circular polarization or right-hand circular polarization. The elliptical polarization includes at least one of the following: left-hand elliptical polarization or right-hand elliptical polarization.

[0078] Step 40B: In response to the polarization type being circular polarization, the target adjustment angle is obtained by searching the database based on the target reflection phase, wherein the database includes the correspondence between the target adjustment angle and the target reflection phase.

[0079] In practice, the initial phase difference between two orthogonally polarized electromagnetic waves is 90 degrees. For example, the phase of the electromagnetic wave in the horizontal direction (x direction) leads the phase of the electromagnetic wave in the vertical direction (y direction) by 90 degrees, and the reflected phases differ by 180 degrees in a wide frequency band.

[0080] When the polarization type of the incident electromagnetic wave is determined to be circular polarization, the reflected phase is adjusted by rotating the angle of the planar magnetoelectric resonator. The target adjustment angle is obtained by searching a database based on the target reflected phase. The database contains a correspondence between the target reflected phase and the target adjustment angle. This correspondence can be in at least one of the following forms: a relational table, a functional relationship, a curve relationship, or a histogram relationship; in this embodiment, a relational table is preferred.

[0081] Step 40C: Adjust the angle of the planar magnetoelectric resonator based on the target adjustment angle to obtain the adjusted planar magnetoelectric resonator.

[0082] In practice, the angle is adjusted according to the target obtained, and the angle of the planar magnetoelectric resonator is adjusted using the rotation unit method to obtain the adjusted planar magnetoelectric resonator.

[0083] For example, taking the upward opening direction of the first open metal ring as the reference phase, i.e., phase 0, when the planar magnetoelectric resonator rotates to the left by an angle of x degrees, the relative reflection phase is 2x degrees.

[0084] In some embodiments, in response to the detection antenna array comprising at least two planar magnetoelectric resonators, for each planar magnetoelectric resonator, after step 401, the method further includes:

[0085] Step 40a: Obtain the polarization type of the incident electromagnetic wave and the target reflection phase.

[0086] In practice, after receiving the incident electromagnetic wave, the planar magnetoelectric resonator first determines the polarization type of the incident electromagnetic wave.

[0087] Step 40b: In response to the polarization type being linear polarization, the target adjustment length is obtained by searching a database based on the target reflection phase, wherein the database includes the correspondence between the target adjustment length and the target reflection phase.

[0088] In specific implementation, linear polarization refers to the electric field vector reciprocating along a line. When the polarization type of the incident electromagnetic wave is determined to be linear polarization, the reflected phase is adjusted by changing the length of the planar magnetoelectric resonator. The target adjustment length is obtained by searching a database based on the target reflected phase. The database contains the correspondence between the target reflected phase and the target adjustment length. This correspondence can be in at least one of the following forms: a relational table, a functional relationship, a curve relationship, and a histogram relationship; in this embodiment, a relational table is preferred. The target reflected phase is a relative value. For example, if the target reflected phase is 315 degrees, the corresponding target adjustment length includes a range value, namely, the maximum and minimum target length values. The target adjustment length is selected from the range of values ​​within which the target adjustment length is defined.

[0089] Step 40c: Adjust the length of the planar magnetoelectric resonator based on the target adjustment length to obtain the adjusted planar magnetoelectric resonator.

[0090] In practice, the length of the planar magnetoelectric resonator is adjusted according to the target length to obtain the adjusted planar magnetoelectric resonator.

[0091] In some embodiments, the length of the planar magnetoelectric resonator includes at least one of the following: the length of the first open metal ring and the length of the complete metal ring; the target adjustment length includes at least one of the following: the target length of the first open metal ring and the target length of the planar magnetoelectric resonator.

[0092] Step 40c specifically includes:

[0093] Step 40c1: Adjust the length of the first open metal ring using the target first open metal ring length.

[0094] In practice, the target adjustment length obtained from the database includes the length of the target first open metal ring and the length of the target planar magnetoelectric resonator. First, the length of the first open metal ring is adjusted according to the target first open metal ring length (i.e.,...). Figure 2 (The length in the y-direction is shown). By adjusting the length of the first open metal ring, the electromagnetic wave resonant frequency in the horizontal direction (i.e., the x-direction) of the planar magnetoelectric resonator is achieved, thereby changing the reflection phase.

[0095] Step 40c2: Calculate the difference between the length of the target planar magnetoelectric resonator and the length of the target first open metal ring.

[0096] In practice, the difference between the length of the target planar magnetoelectric resonator and the length of the target first open metal ring is calculated, and the difference is the target length of the complete metal ring.

[0097] Step 40c3: Adjust the length of the complete metal ring using the difference.

[0098] In practice, the length of the complete metal ring is adjusted based on the difference calculated in the above steps, thereby achieving the electromagnetic wave resonant frequency in the vertical direction (i.e., the y-direction) of the planar magnetoelectric resonator and thus changing the reflection phase. Magnetic resonance and electric resonance have excellent mode isolation, and the phases of the incident electromagnetic waves polarized in the two directions can be manipulated independently.

[0099] The above scheme utilizes a purely planar structure for the planar magnetoelectric resonator. The magnetic resonance state can be adjusted by changing the length of the first open metal ring, and the electrical resonance state can be adjusted by changing the length of the complete metal ring, simplifying the tuning process. Furthermore, adjustments are made based on pre-built database relationships, resulting in more accurate tuning.
