Pitching surface large-angle wave beam coverage series feed array

Abstract

The utility model discloses a pitching surface wide-angle wave beam coverage series feed array, which comprises N series feed arrays, each series feed array comprises a data processing chip, the data processing chip is connected with a plurality of array units in series through a feed circuit, the feed circuit comprises a main circuit connected with a radio frequency port of the data processing chip, and the main circuit is connected with the radio frequency port of the data processing chip. The main circuit is divided into two secondary branches towards two sides, the two secondary branches are respectively provided with four tertiary branches, a plurality of array units are arranged on the four tertiary branches, the array units and the feed circuit are arranged on the metal floor, and the arrangement mode of the N series feed arrays is that the N series feed arrays are opposite in the transverse direction and correspond to each other in the longitudinal direction; through the optimized and improved design of the product, the wave beams respectively point to different directions to form a multi-beam antenna, so that the total wave beam coverage range is increased under the condition that the detection distance is not reduced, the detection range is broadened, and the purpose of expanding the radar detection range is further achieved.
