A kind of manufacturing method of high-strength hyperboloid conformal microstrip slot antenna

Abstract

The invention proposes a method for manufacturing a high-strength hyperboloid conformal microstrip slot antenna, which mainly solves the problem of poor conformal matching between the antenna and the carrier manufactured in the prior art, which will destroy the aerodynamic layout of the carrier. The manufacturing steps are as follows: manufacturing a metal base plate (3), a shaping pressure plate (6) and a bonding pressure plate (7) according to the requirements of the hyperboloid carrier; processing the rigid dielectric substrate material into a flat plate-shaped dielectric substrate by using the microwave printed board technology, and Use a shaping platen to gradually hot-press and shape it to obtain a dielectric substrate (1); use a bonding platen to assemble and fix the metal base plate, the dielectric substrate, and the radio frequency connector (4) through the heat-curing adhesive film (2), and use high The low-temperature press is hot-pressed and cured, and then the three-proof coating (5) is sprayed to complete the entire antenna production. The antenna produced by the invention has the advantages of good adaptability to the mechanical environment, high conformal matching degree with the carrier and small scattering area, and can be used on aircraft or other mobile platforms with high requirements for stealth and aerodynamic performance.
