Abstract
The invention belongs to the technical field of antennas, and discloses a planar slot array antenna, a radar, a wireless communication system and a millimeter wave antenna. The planar slot antenna array is provided with a planar slot array, a feed plate, a power division network and an output plate, wherein the base material of the planar slot antenna array is fiber-reinforced special engineeringplastic; a chemical plating layer, a metallized signal layer and a protective layer are sequentially arranged on the base material; and the planar slot antenna array 1 comprises 44 isolation square cavities, 44 radiation slots and 6 excitation waveguide cavities, and the power division network 3 is formed by cascading a plurality of waveguide power dividers with equal arm length and equal power division. Compared with a traditional metal planar waveguide slot antenna, the planar slot array antenna has the advantages of light weight, weight reduction by 30% or more, simple processing, low production cost, wide frequency band and efficiency, high gain, far wireless signal propagation distance and high temperature resistance; and the structural mass of aerospace rockets and missile weapons can be reduced, and the effective load and the fighting capacity of the aerospace rockets and missile weapons are improved.
Description
technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a flat panel slot array antenna, a radar, a wireless communication system, and a millimeter wave antenna. Background technique [0002] At present, as radar is widely used in the fields of land, sea, air force and civil aviation meteorology, the application of radar antenna is becoming more and more extensive. The existing radar antenna products are all made of zinc (aluminum) alloy die-casting or machining, and then through the surface After grinding or machining, do electro-silver plating, electro-tin plating and other surface conductive treatments; this kind of antenna is heavy, high production cost, and complicated process, which can no longer meet the needs of my country's aerospace and military industrial missiles for lightweight, high temperature resistance, and low cost. [0003] In the prior art, microwave devices used in aerospace vehicles mostly use carbon ...
