[0032] Reference figure 1 The antenna array includes a plurality of dual-polarized antenna arrays 1, and the plurality of dual-polarized antenna arrays 1 are arranged side by side along the arrangement direction Y. Reference figure 2 with image 3 , The following describes one of the dual-polarized antenna array 1. The dual-polarized antenna array 1 is arranged in a multi-layer microstrip structure. The horizontal and vertical spacing of the radiation patches in the array is about 1 / 2 wavelength. The X-band antenna For example, the horizontal spacing is about 1.7cm, and a row of 1*N-element fixed-beam dual-polarized linear array is formed by horizontal N array elements, that is, an antenna module. The dual-polarized antenna array 1 is provided with radiating patches 11 from top to bottom. , The second dielectric layer 22, the coupling gap component, the first dielectric layer 21, the polarization feeder component and the radio frequency joint pad.
