Embodiment Construction
[0023] refer to figure 1 . An antenna feed calibration network described in the embodiment of the present invention mainly includes three parts: the upper antenna metal floor 1 , the middle antenna combiner feed network 2 and the lower antenna calibration network 3 . The upper antenna metal floor 1, the middle antenna combiner feed network 2 and the lower antenna calibration network 3 with a symmetrical structure, the upper antenna metal floor 1 is the top layer, and the upper antenna metal floor 1 is equipped with the corresponding middle antenna combiner feed network 2 The embedding grooves of each combiner module 7 are staggered at the same interval to bury each combiner module 7 in the metal floor. The combiner is installed in blocks, and each two-unit sub-array The two combiners required for polarization are used as a module, and are fastened together with the upper antenna metal floor 1 in the form of block installation to form the feed network of the middle antenna com...
