[0003] Currently, 60GHz millimeter wave radars usually adopt a 2T3R scheme, that is, 2 transmitting antennas and 3 receiving antennas. However, the current layout and spacing of the antenna array cannot meet the design requirements of an equivalent 1T6R, that is, 1 transmitting antenna and 6 receiving antennas, resulting in the receiving gain of the radar system not reaching the expected effect, which is not conducive to the overall performance of the antenna system.
[0004] Therefore, the existing technology still needs to be improved. Summary of the Utility Model

[0035] The purpose of this application is to provide an antenna structure, antenna device, and electronic device that can alleviate the problem that current antenna designs cannot achieve the expected receiving gain, thereby improving the overall performance of the antenna system.
[0036] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description of this application is provided with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0037] Please see Figure 1 This application provides an antenna structure including a substrate 10. One side surface of the substrate 10 has multiple antenna modules 11, each including at least two receiving modules and at least two transmitting modules. The receiving modules are located in a first region, and the transmitting modules are located in a second region adjacent to the first region; that is, the receiving and transmitting modules are distributed in different regions. For example, if the multiple antenna modules 11 include three receiving modules (R1, R2, and R3) and two transmitting modules (T1 and T2), the three receiving modules are concentrated in the right side region of the substrate 10, while the two transmitting modules are relatively concentrated in the left side region of the substrate 10. This separate arrangement of the receiving and transmitting modules helps to avoid interference between them.
[0038] In the first region, adjacent receiving modules are spaced apart by half a vacuum wavelength, and this spacing can be the center-to-center spacing between two receiving modules, as shown by d1 in the figure. Similarly, in the second region, adjacent transmitting modules are spaced apart by one and a half vacuum wavelengths, and again, this spacing can be the center-to-center spacing between two transmitting modules, as shown by d2 in the figure. In this embodiment, the vacuum wavelength refers to the wavelength corresponding to the centerline frequency when electromagnetic waves propagate in a vacuum. Arranging the receiving modules at half-wavelength intervals effectively forms a specific beam pattern and helps improve the resolution of incoming waves from different directions. For example, in radar systems, this layout can more accurately distinguish targets at different angles, improving target positioning accuracy. At the same time, setting the receiving modules at half-wavelength intervals can reduce mutual coupling between receiving modules to a certain extent, resulting in relatively weak electromagnetic field interaction between antennas, thereby reducing signal distortion and interference. Setting the transmitting modules to one and a half vacuum wavelengths allows them to form a specific radiation pattern. When two antennas transmit signals simultaneously, due to the spacing of one and a half (1.5 times) vacuum wavelengths, the radiation fields in some directions reinforce each other, while in others they cancel each other out, thus creating a specific radiation pattern. Meanwhile, a 1.5-times vacuum wavelength spacing allows for effective control of sidelobe levels by adjusting antenna excitation, reducing interference in other directions. In radar systems, lower low-lobe levels reduce false positives for other targets, improving radar detection accuracy.
[0039] In this application, multiple receiving modules and multiple transmitting modules are arranged in the substrate 10. When the interval between the transmitting modules is set to be equal to three times the interval between the receiving modules, the signals of the transmitting modules and the receiving modules can be combined. In the equivalent signal processing process, more receiving modules are simulated to be equivalent to a 1T6R array. Thus, it is equivalent to increasing the number of receiving modules, thereby improving the intensity of the received signal, making the receiving gain of the antenna structure reach the expected effect, and being beneficial to improving the overall performance of the antenna system.
[0040] Please refer to Figure 2 , in some embodiments, the interval between the receiving modules and the transmitting modules with similar intervals between the first region and the second region is d, where 1.5λ0 < d < 2.5λ0, and λ0 is the vacuum wavelength. The interval between the adjacent receiving module and the transmitting module can be the edge interval where the two antennas are close. For example, the interval between the adjacent receiving module and the transmitting module is about two vacuum wavelengths, that is, the interval between the receiving module R1 and the transmitting module T2 is about two vacuum wavelengths. Regarding multiple receiving modules as a whole and multiple transmitting modules as a whole, the minimum interval between the two wholes is about two vacuum wavelengths, and the electromagnetic field interaction between the antennas is relatively weak. The receiving module can receive signals more accurately and avoid being interfered by the transmitting module. Thus, the coupling interference between the receiving module and the transmitting module can be reduced. In practical applications, the volume and size of the antenna structure are often limited. By optimizing the spacing between the transmitting module and the receiving module, a compact layout of the antenna structure can be achieved while ensuring the antenna performance, which is beneficial to the miniaturization setting of the antenna structure.
[0041] As an embodiment, multiple receiving modules and multiple transmitting modules are both arranged along the first direction, and the first direction is the interval direction between the first region and the second region, such as the direction where d is located. In the first region, multiple receiving modules are arranged along the interval direction between the first region and the second region. Similarly, in the second region, multiple transmitting modules are arranged along the interval direction between the first region and the second region. In this way, it is equivalent to arranging multiple antenna modules in the same direction, which is beneficial to increasing the interval between the receiving module and the transmitting module in different regions, thereby reducing the crosstalk problem between the receiving antenna and the transmitting antenna.
[0042] Please refer to Figure 3 , in some embodiments, each antenna module 11 includes a microstrip line 111 and multiple antenna units 112 connected in series through the microstrip line 111, and the multiple antenna units 112 are arranged along the second direction, and the second direction intersects with the first direction; as an embodiment, the first direction and the second direction can be two perpendicular directions.
[0043] Each antenna unit 112 is rectangular. The length of each antenna unit 112 along the second direction is h, and the width of each antenna unit 112 is w, where 0.6h ≤ w ≤ 0.8h. Thus, the width of the antenna unit 112 is less than the length of the antenna unit 112. Relatively speaking, in this embodiment, the width of each antenna unit 112 is set to be relatively small, thereby reducing the width of the antenna, increasing the aspect ratio of the antenna unit 112, which is equivalent to reducing the lateral aperture of the antenna, and thus expanding the H-plane beam width.
[0044] As an embodiment, each antenna module 11 includes two antenna units 112. By setting two antenna units 112, compared with setting multiple antenna units 112, the number of antenna units 112 is reduced, which is beneficial to reducing the size of the antenna structure.
[0045] As an embodiment, the microstrip lines 111 in each receiving module are of equal length, and the microstrip lines 111 in each transmitting module are of equal length. By setting the microstrip lines 111 to be of equal length, it can ensure that the signals have the same phase delay when reaching each antenna unit 112, thus achieving phase consistency. At the same time, the equal-length microstrip lines 111 can ensure that the signal amplitudes received by each antenna unit 112 are basically the same, thereby avoiding pattern distortion or gain non-uniformity caused by amplitude differences, and thus improving the overall performance of the antenna.
[0046] As an embodiment, the length of the microstrip line 111 is a, where 0.3λg < a < 1.2λg, and λg is the dielectric wavelength, which refers to the wavelength of electromagnetic waves when propagating in a specific dielectric. For example, the length of the microstrip line 111 can be 0.5λg. In this embodiment, by precisely controlling the length of the microstrip line 111, precise control of the phase difference between the antenna units 112 can be achieved. When the length of the microstrip line 111 is half of the dielectric wavelength, a 180-degree phase difference will occur during signal transmission. This phase difference can be precisely adjusted by adjusting the length of the microstrip line 111, thereby achieving beam pointing control. The length of the half-dielectric wavelength microstrip line 111 is relatively moderate, neither too long to cause the antenna size to be too large nor too short to result in the inability to achieve the required impedance matching and radiation performance. By reasonably selecting the length of the microstrip line 111, the antenna size can be optimized while ensuring the antenna performance. In millimeter-wave communication, the design of the half-dielectric wavelength microstrip line 111 can effectively reduce reflection and standing wave effects during signal transmission, thereby improving the communication performance of the system.
[0047] Compared to the current antenna element 112 layout, the length of the microstrip line 111, which is half a dielectric wavelength, is equivalent to increasing the length of the microstrip line 111. Therefore, when laying out the straight microstrip line 111, the spacing between the antenna elements 112 can be increased to increase the length of the antenna module 11, which is equivalent to increasing the E-plane aperture of the antenna array. The antenna E-plane beam is further compressed to improve the gain.
[0048] Please see Figure 4 As one embodiment, at least a portion of the microstrip line 111 is curved. For example, by setting the microstrip line 111 in the receiving module T1 to a curved shape, the spacing between antenna elements 112 can be reduced while maintaining the same length of the microstrip line 111, thus facilitating the layout of the antenna module 11 within a limited space. In a specific embodiment, at least a portion of the microstrip line 111 is arc-shaped, and the radius of the circle containing the arc-shaped microstrip line 111 is r, where r ≥ 3b, and b is the width of the microstrip line 111.
[0049] As one embodiment, the dielectric constant of substrate 10 is less than 4. Dielectric constant is a physical quantity that describes the effect of a material on an electric field. The larger the dielectric constant, the slower the propagation speed of electromagnetic waves in the medium. A smaller relative dielectric constant means that electromagnetic waves propagate relatively faster in the substrate layer, with smaller wavelength changes, which is beneficial for reducing electromagnetic wave loss and dispersion during propagation.
[0050] The loss tangent of substrate 10 is less than or equal to 0.005. The loss tangent is a parameter that measures the energy loss of a dielectric material under an alternating electric field. It reflects the dielectric's ability to convert electrical energy into heat energy. During electromagnetic wave transmission, the smaller the loss tangent of the substrate layer, the less energy is lost due to dielectric loss when the electromagnetic wave propagates in the substrate layer, thus ensuring that the electromagnetic wave is transmitted with higher intensity and efficiency.
[0051] As one embodiment, the transmitting module and the receiving module are arranged as a whole and positioned as centrally as possible on the substrate 10. This ensures good symmetry of the antenna's radiation pattern in all directions, reduces radiation pattern distortion, and improves the antenna's directional gain. Simultaneously, arranging the transmitting and receiving modules as a whole close to the center of the substrate 10 ensures proper spacing between the antennas, thereby reducing coupling effects.
[0052] In the antenna structure of this embodiment, by arranging the spacing between the transmitting module and the receiving module, the antenna structure is equivalent to the effect of a 1T6R antenna array, thereby increasing the number of receiving modules, improving the intensity of the received signal, achieving the expected effect of the receiving gain of the antenna structure, and being beneficial to improving the overall performance of the antenna system. By setting the antenna element 112 with a relatively small width, the transverse aperture can be reduced, thereby expanding the H-plane beam width. By setting the relatively long microstrip line 111, it is beneficial to increase the length of the entire antenna module 11, which is equivalent to increasing the E-plane aperture of the antenna array, further compressing the E-plane beam, and increasing the gain. When the layout space is not satisfied, the microstrip line 111 can be set in a curved shape, which is beneficial to the miniaturization of the antenna structure.
[0053] Please refer to Figure 5 , this embodiment of the present application also provides an antenna device, which includes the above-mentioned antenna structure 1 and an antenna cover 2. The antenna cover 2 is a structure that protects the antenna structure 1 from the external environment. At the same time, it is necessary to ensure the effective transmission of electromagnetic waves within the normal operating frequency range of the antenna structure 1, reduce the loss and reflection of electromagnetic waves during transmission, and play a key role in protecting and optimizing the electrical performance of the antenna structure 1.
[0054] Among them, the antenna cover 2 is arranged at an interval from the antenna structure 1, and the antenna cover 2 is located on one side of the substrate 10 where the antenna module 11 is arranged. The interval between the antenna cover 2 and the antenna structure 1 is s, and 0.6λ0 < s < 1.5λ0. For example, the interval between the antenna cover 2 and the antenna structure 1 is one vacuum wavelength, that is, 1λ0. Setting a certain interval between the antenna cover 2 and the antenna structure 1 can reduce the probability that external electromagnetic interference is reflected onto the antenna structure 1 through the antenna cover 2, thereby improving the anti-interference ability of the antenna device. At the same time, when the distance, that is, a certain interval, such as one vacuum wavelength, the influence of the antenna cover 2 on the propagation of electromagnetic waves is the smallest, and it can better maintain the radiation pattern characteristics of the antenna. This design can reduce the distortion of the antenna radiation pattern, ensure that the main beam direction and sidelobe level of the antenna meet the design requirements, and thus improve the directivity and gain of the antenna.
[0055] As an embodiment, the antenna cover 2 has a narrow wave-transmitting window. The narrow wave-transmitting window refers to a specific area designed on the antenna cover 2 that allows electromagnetic waves to pass through, while other areas may have a strong attenuation effect on electromagnetic waves. If there are two antenna elements 112 in the antenna module 11 in the antenna structure 1, the centers of the two antenna elements 112 in the antenna module 11 can be close to the transverse center of the narrow wave-transmitting window, thereby ensuring the symmetry of the antenna array. By placing the centers of the two antenna elements 112 in the antenna module 11 close to the center of the narrow wave-transmitting window or at the center of the narrow wave-transmitting window, the wave-transmitting effect of the antenna cover can be maximized, thereby optimizing the radiation pattern of the antenna.
[0056] Please see Figure 6 , Figure 6 Antenna pattern of the antenna device provided in the embodiments of this application. Figure 6 The horizontal axis represents the antenna radiation direction angle, usually in degrees; the vertical axis represents the antenna gain or signal strength, usually in decibels (dB). Curve S1 represents the combined gain of transmitting module T1 and receiving module R1, curve S2 represents the combined gain of transmitting module T2 and receiving module R1, curve S3 represents the combined gain of transmitting module T2 and receiving module R2, curve S4 represents the combined gain of transmitting module T1 and receiving module R3, and curve S5 represents the combined gain of transmitting module T2 and receiving module R3. Combining the antenna pattern, it can be seen that the antenna device of this application can achieve effective transmission of millimeter-wave radar beams within a large azimuth angle range of ±60° at certain specific frequencies (e.g., in the case of receiving and transmitting millimeter-wave radar beams). If this antenna device is applied to a television set, this advantage allows the television set to receive millimeter-wave signals without being limited by the antenna installation angle, enabling signal reception from a wider range of directions and improving the stability and reliability of signal reception. For example, in complex indoor environments, the position of the television set may be affected by factors such as furniture placement, preventing the antenna from directly pointing towards the signal source. The wide-angle wave transmission capability of the antenna device in this application can ensure that the television can still receive a strong signal, thus guaranteeing a good viewing experience.
[0057] Please see Figure 7 , Figure 7 This is an antenna pattern for a single antenna module 11 provided in an embodiment of this application. The horizontal axis represents the angle Theta in degrees; the vertical axis represents the gain Mag in dB. As can be seen from this antenna pattern, a single antenna module 11 can achieve effective transmission of millimeter-wave radar beams within a large azimuth angle range of ±60° at certain specific frequencies (e.g., when receiving and transmitting millimeter-wave radar beams).
[0058] Please see Figure 8 , Figure 8This is a schematic diagram of the S-parameters of the antenna device provided in an embodiment of this application. The S-parameters characterize the ability to reflect and transmit signals at different ports. The figure shows curves for four S-parameters, typically represented as S11, S21, S12, and S22. S11 and S21 represent the reflection coefficients in the antenna network, and S21 and S22 represent the transmission coefficients between antennas. In the figure, these parameters are labeled as dB(S(T1, R1)), dB(S(T2, R1)), dB(S(T1, R2)), and dB(S(T2, R2)). dB(S(T1, R1)) and dB(S(T2, R1)) correspond to the input reflection coefficients of the antennas, while dB(S(T2, R1)) and dB(S(T1, R2)) correspond to the transmission coefficients between antennas.
