一种贴片天线阵列及通信系统A patch antenna array and communication system

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种贴片天线阵列及通信系统。The present invention relates to the field of communication technologies, and in particular, to a patch antenna array and a communication system.

背景技术Background technique

贴片天线阵列是由多个贴片天线单元组成的天线。可以是固定波束的阵列天线，也可以是相控阵天线。由于天线单元之间的距离较近，通常为半波长左右，单元之间存在较强的互耦，周围不同单元到某一考察单元的耦合，有不同的幅度与相位。当大部分耦合场以基本相近的相位叠加时，阵列就会出现较大的有源阻抗失配，形成较大的反射，降低阵列辐射性能。A patch antenna array is an antenna composed of multiple patch antenna elements. It can be a fixed beam array antenna or a phased array antenna. Due to the short distance between antenna units, usually about half a wavelength, there is strong mutual coupling between units, and the coupling from different surrounding units to a certain unit under investigation has different amplitudes and phases. When most of the coupled fields are superimposed with a substantially similar phase, the array will have a large active impedance mismatch, resulting in a large reflection and reducing the radiation performance of the array.

参考图1，本发明实施例提供了一种贴片天线阵列，贴片天线阵列包括：Referring to FIG. 1, an embodiment of the present invention provides a patch antenna array, and the patch antenna array includes:

贴片天线单元101，贴片天线单元101的数量为M×N个，贴片天线单元101排布为M×N的矩阵，其中，M和N均为大于等于2的整数；Thepatch antenna unit 101, the number of thepatch antenna units 101 is M×N, and thepatch antenna units 101 are arranged in an M×N matrix, wherein M and N are both integers greater than or equal to 2;

开口103，开口103设置于隔离墙102上。The opening 103 is arranged on thepartition wall 102 .

本实施例中通过贴片天线单元101之间的隔离墙102上设置开口103，去除掉一部分隔离墙102的金属，从而能改变不同方向单元之间的耦合相位，根据需要选择合适的开槽宽度与隔离墙102厚度，可以大大改善阵列的有源反射。In this embodiment, theopenings 103 are provided on thepartition walls 102 between thepatch antenna units 101, and a part of the metal of thepartition walls 102 is removed, so that the coupling phase between the units in different directions can be changed, and the appropriate slot width can be selected according to the needs. With the thickness of theisolation wall 102, the active reflection of the array can be greatly improved.

在一实施例中，的隔离墙102还设置有多个过孔104。In one embodiment, theisolation wall 102 is further provided with a plurality ofvia holes 104 .

在一实施例中，开口103填充有介质材料。In one embodiment, theopenings 103 are filled with a dielectric material.

本实施例中，贴片天线单元101之间的金属隔离墙102可以是实体的金属结构，也可以是如图2所示的金属化的过孔104与带线组成的。隔离墙102的开槽，是指去除了隔离墙102的一部分金属，去除后的空间可以是由介质填充，也可以是空气或真空。In this embodiment, themetal partition wall 102 between thepatch antenna units 101 may be a solid metal structure, or may be composed of a metallized viahole 104 and a strip line as shown in FIG. 2 .

如图3所示，图3显示了现有技术中隔离墙102并未设置开口103时的贴片天线阵列的几个耦合矢量叠加情况，可以看到，合成矢量较大，对应了阵列较大的有源反射；而本实施例在隔离墙102设置开口103后，这几个耦合矢量的合成矢量明显减小，如图4所示，阵列有源反射得到很大改善，辐射性能得到明显提升。As shown in FIG. 3, FIG. 3 shows the superposition of several coupling vectors of the patch antenna array when theseparation wall 102 is not provided with theopening 103 in the prior art. It can be seen that the combined vector is larger, which corresponds to the larger array. However, in this embodiment, after theopening 103 is provided in theisolation wall 102, the composite vector of these coupling vectors is significantly reduced. As shown in FIG. 4, the active reflection of the array is greatly improved, and the radiation performance is significantly improved .
