技术领域technical field
本发明属于天线技术领域，具体涉及一种新型LTCC基因组单元紧凑共形阵列天线。The invention belongs to the technical field of antennas, in particular to a novel LTCC genome unit compact conformal array antenna.
背景技术Background technique
随着现代信息技术和新军事革命的蓬勃发展，未来战争将向着陆、海、空、天、电五维一体发展。雷达作为电磁波探测设备，在未来战场上发挥的作用必将越来越重要。阵列天线作为雷达系统发射和接收电磁波的部件，其性能的好坏，直接影响着雷达探测结果的准确性，所以对于雷达系统，阵列天线的设计显得尤为重要。阵列天线有着多种多样的形式，而微带天线相较于其他微波天线有着明显的优势：体积小、重量轻，低剖面、易与载体共形，最大辐射方向与极化形式易于控制，易与有源/无源器件集成等。以微带单元组成的阵列天线，体积小、集成度高，并且可以实现提高增益、增强方向性、提高辐射效率、降低副瓣、形成赋形波束和多波束等特性；圆极化微带贴片阵列天线不仅具有以上天线的优点，还能接收和发射全向电磁波，应用更广泛。在实现微带贴片天线圆极化方面，目前常见的有采用多馈电和进行贴片切角的方法，但前者增加了天线结构的复杂度，使天线的增益降低，后者对贴片切角的尺寸精度要求较高。圆极化微带贴片阵列天线兼顾其低剖面、圆极化、高增益、宽频带的矛盾始终未得到很好的解决。With the vigorous development of modern information technology and the new military revolution, future warfare will develop into a five-dimensional integration of landing, sea, air, space, and electricity. As an electromagnetic wave detection device, radar will play an increasingly important role on the future battlefield. As a part of the radar system to transmit and receive electromagnetic waves, the performance of the array antenna directly affects the accuracy of the radar detection results. Therefore, for the radar system, the design of the array antenna is particularly important. Array antennas have a variety of forms, and microstrip antennas have obvious advantages over other microwave antennas: small size, light weight, low profile, easy to conform to the carrier, easy to control the maximum radiation direction and polarization form, easy to Integration with active/passive devices, etc. The array antenna composed of microstrip units is small in size and highly integrated, and can achieve the characteristics of increasing gain, enhancing directivity, improving radiation efficiency, reducing sidelobes, forming shaped beams and multi-beams; circularly polarized microstrip stickers The chip array antenna not only has the advantages of the above antennas, but also can receive and transmit omnidirectional electromagnetic waves, and has a wider range of applications. In terms of realizing the circular polarization of the microstrip patch antenna, the methods of multi-feed and patch angle cutting are commonly used at present, but the former increases the complexity of the antenna structure and reduces the gain of the antenna, and the latter is harmful to the patch The dimensional accuracy of the cut corners is required to be high. The contradiction of circularly polarized microstrip patch array antenna taking into account its low profile, circular polarization, high gain, and wide frequency band has not been well resolved.
LTCC(低温共烧陶瓷技术)作为一种多层陶瓷技术，其多层化过程中采用了流延和通孔技术，使得加工方便，并且可提供比常规基板材料更好的层厚控制，将微带天线的结构由传统的一维扩充到三维，改变了传统微带天线的设计模式，对于提高雷达天线系统集成度可发挥巨大作用；同时，LTCC材料的介电常数可在2～20000之间变化，能适应于不同的工作频率。因此，LTCC技术与微带天线结合已成为新的研究热点。As a multilayer ceramic technology, LTCC (Low Temperature Co-fired Ceramic Technology) adopts tape casting and through-hole technology in the multilayering process, which makes processing easier and provides better layer thickness control than conventional substrate materials. The structure of the microstrip antenna has been expanded from the traditional one-dimensional to three-dimensional, which has changed the design mode of the traditional microstrip antenna, and can play a huge role in improving the integration of the radar antenna system; at the same time, the dielectric constant of the LTCC material can be between 2 and 20,000 It can be adapted to different operating frequencies. Therefore, the combination of LTCC technology and microstrip antenna has become a new research hotspot.

The feeding network is connected to the feeding port through the metal coaxial probe passing through the lower dielectric substrate. The coaxial probe is provided with a through hole; it is characterized in that the lower layer metal patch antenna is composed of several lower layer metal patch units arranged in an array, and each lower layer metal patch unit is a rectangle with diagonally cut corners Metal patch, and rectangular grooves are opened at the cut corners, and at the same time, the lower metal patch unit has rectangular slots on the other three sides except the feeding side; the upper metal patch antenna is connected with the lower metal patch unit Correspondingly set upper metal patch sub-arrays are formed, each upper layer metal patch sub-array and the center of the corresponding lower layer metal patch unit overlap to form a genome unit together, and the upper layer metal patch sub-arrays are arranged in a 2×2 array It consists of 4 upper metal patch units, and each upper metal patch unit also adopts a rectangular metal patch with diagonal and cut corners, and rectangular grooves are opened at the cut corners, and the four sides of the upper metal patch unit are opened rectangular gap.
进一步的，所述每个上层金属贴片子阵中的4个上层金属贴片单元两两之间边缘间距为0.1～0.13个中心频率处的真空波长。Further, the edge spacing between two pairs of the four upper metal patch units in each upper metal patch sub-array is 0.1-0.13 vacuum wavelengths at the center frequency.
所述每个上层金属贴片子阵中的4个上层金属贴片单元及其对应的下层金属贴片单元上开设的矩形缝隙尺寸相同。The four upper metal patch units in each upper metal patch sub-array and the corresponding lower metal patch units have the same size of rectangular slits.
所述馈电网络与下层金属贴片天线相连，馈电网络采用四分之一波长变换段与同轴金属探针连接，采用四分之一波长变换段与下层金属贴片单元相连接，在转角处均采用四分之一圆环即扫略弯头连接，在宽度不同的带状线连接处采削角阶梯连接。The feed network is connected to the lower metal patch antenna, the feed network is connected to the coaxial metal probe by a quarter wavelength conversion section, and the quarter wavelength conversion section is connected to the lower metal patch unit. The corners are connected by a quarter-circle, that is, a sweeping elbow, and the connection of striplines with different widths is connected by steps with cut corners.

需要特别说明的是：What needs special explanation is:
1、本发明中，上层金属贴片子阵之间间距略大于二分之一波长，上层金属贴片子阵距离介质基板的对应边缘的距离要大于1/4中心频率处的真空波长。1. In the present invention, the spacing between the upper metal patch sub-arrays is slightly greater than 1/2 wavelength, and the distance between the upper metal patch sub-arrays and the corresponding edge of the dielectric substrate is greater than the vacuum wavelength at the 1/4 center frequency.
2、上层金属贴片单元和下层金属贴片单元的对角加切角处开矩形凹槽是控制天线圆极化的主要因素，调节每个阵元里金属辐射贴片单元尺寸和所开矩形凹槽的大小，保证单点馈电矩形贴片产生幅度相等的两个正交简并模形成90°的相位差；同时，下层金属贴片单元采用三边开非对称开设矩形缝隙，上层金属贴片单元采用每边对称开有矩形缝隙，形成微扰，各上层金属贴片单元及下层金属贴片单元尺寸各不相同，形成多种微扰和耦合模式，大大增加天线的频率带宽，且在保证中心频率不变的情况下大大减小金属辐射贴片的尺寸；并且由上层金属贴片子阵和下层金属贴片单元组成的基因组阵元可通过调节任一金属贴片单元的尺寸和形状来调节整个阵列天线的性能，实现基因组操作，从而实现可持续性发展。2. Opening rectangular grooves at the diagonal and cut corners of the upper metal patch unit and the lower metal patch unit is the main factor to control the circular polarization of the antenna. Adjust the size of the metal radiation patch unit in each array element and the opened rectangle The size of the groove ensures that the single-point feeding rectangular patch produces two orthogonal degenerate modes with equal amplitudes to form a 90° phase difference; at the same time, the lower metal patch unit uses three sides to open asymmetrical rectangular slots, and the upper metal patch unit The patch unit adopts a symmetrical rectangular slit on each side to form perturbation. The size of each upper metal patch unit and the lower metal patch unit is different, forming a variety of perturbation and coupling modes, greatly increasing the frequency bandwidth of the antenna, and While keeping the central frequency unchanged, the size of the metal radiation patch is greatly reduced; and the genome array element composed of the upper metal patch sub-array and the lower metal patch unit can be adjusted by adjusting the size and shape of any metal patch unit To adjust the performance of the entire array antenna, to achieve genome manipulation, so as to achieve sustainable development.
3、下层介质基板上的馈电网络的线宽要应根据基板的介电常数大小和厚度进行适当调节，以确保与同轴金属探针连接的1/4波长变换段的阻抗为50欧姆。3. The line width of the feed network on the lower dielectric substrate should be properly adjusted according to the dielectric constant and thickness of the substrate to ensure that the impedance of the 1/4 wavelength conversion section connected to the coaxial metal probe is 50 ohms.
4、下层介质基板和上层介质基板所采用LTCC陶瓷材料的相对介电常数范围为2～100。4. The relative permittivity range of the LTCC ceramic material used for the lower dielectric substrate and the upper dielectric substrate is 2-100.
本发明与现有技术相比，具有如下优点和有益效果：1)该天线采用单馈电，结构简单、加工方便，利用加切角正方形金属贴片开矩形凹槽的形式实现圆极化，有效提升圆极化性能，并且圆极化性能调节简单方便；2)采用在上层金属贴片单元每边对称开设矩形缝隙、下层金属贴片单元除馈电边以外的三边非对称开设矩形缝隙的形式，利用非对称缝隙微扰法使天线的频率带宽得到大大提升，并且在相同中心频率的条件小，可减小金属贴片的尺寸，同时还使天线的轴比得到优化，带宽得到一定程度的展宽；3)一个基因组单元中金属贴片单元尺寸各不相同，大大扩展天线带宽，且通过调节任一单元的尺寸从而实现各种不同目标及要求的天线功能，实现可持续行发展；4)基因组中上、下层金属贴片单元形成上下耦合，上层金属贴片单元之间形成前后左右的耦合和微扰，激励起更多模式，从而大大增加了天线带宽；5)在馈电网络不同的转接口处采用不同的不连续性补偿形式，使传输线的能量反射降低，从而提高了天线的整体增益；6)上层LTCC基板上开圆柱形通孔，不仅方便金属探针与传输线之间的焊接，而且不影响天线整体的圆极化，同时还可通过调节窗口的尺寸来调节天线的整体性能，从而增加天线的整体频率带宽；7)该天线充分利用了LTCC技术的优点，对不同叠层之间进行紧密无间隙结合，从而实现整个天线的共形设计，而使天线尺寸减小，性能提升。综上，本发明能够在相同阵元数目限制下尺寸更小、增益更高、圆极化性能更好，而且频率带宽也更宽，并且结构简单易于加工。Compared with the prior art, the present invention has the following advantages and beneficial effects: 1) The antenna adopts a single feed, has a simple structure and is convenient to process, and realizes circular polarization by using a square metal patch with cut corners to open a rectangular groove, Effectively improve the circular polarization performance, and the adjustment of the circular polarization performance is simple and convenient; 2) A rectangular slot is symmetrically opened on each side of the upper metal patch unit, and asymmetrical rectangular slots are opened on the three sides of the lower metal patch unit except the feeding side In the form of the asymmetric slot perturbation method, the frequency bandwidth of the antenna is greatly improved, and the condition of the same center frequency is small, the size of the metal patch can be reduced, and the axial ratio of the antenna is also optimized, and the bandwidth is obtained to a certain extent. 3) The size of the metal patch unit in a genome unit is different, which greatly expands the antenna bandwidth, and by adjusting the size of any unit, various antenna functions with different goals and requirements can be realized, and sustainable development can be achieved; 4) The upper and lower metal patch units in the genome form up-down coupling, and the upper-layer metal patch units form front-back, left-right coupling and perturbation to stimulate more modes, thereby greatly increasing the antenna bandwidth; 5) In the feed network Different forms of discontinuity compensation are used at different adapters to reduce the energy reflection of the transmission line, thereby improving the overall gain of the antenna; 6) A cylindrical through hole is opened on the upper LTCC substrate, which is not only convenient for the connection between the metal probe and the transmission line welding without affecting the overall circular polarization of the antenna. At the same time, the overall performance of the antenna can be adjusted by adjusting the size of the window, thereby increasing the overall frequency bandwidth of the antenna; The stacked layers are closely combined without gaps, so as to realize the conformal design of the entire antenna, reduce the size of the antenna, and improve the performance. To sum up, the present invention can have smaller size, higher gain, better circular polarization performance, wider frequency bandwidth, and simple structure and easy processing under the same limit of the number of array elements.
