Abstract

The invention provides a manufacturing method of a high-strength double-curved-surface conformal microstrip slot antenna, and mainly solves the problems that the conformal matching degree of an antenna manufactured in the prior art and a carrier is poor, and the aerodynamic layout of the carrier is damaged. The manufacturing method comprises the steps that a metal bottom plate (3), a shaping pressing plate (6) and a bonding pressing plate (7) are manufactured according to the requirement of the double-curved-surface carrier; a rigid dielectric substrate material is processed into a flat-plate-shaped dielectric substrate through a microwave printed board technology, and the flat-plate-shaped dielectric substrate is subjected to step-by-step hot-pressing molding by using a molding pressing plate to obtain a dielectric substrate (1); and the metal base plate, the dielectric substrate and a radio frequency connector (4) are assembled and fixed through the thermocuring adhesive film (2) by using a bonding pressing plate, hot-pressing curing is performed by using a high and low temperature press machine, and then a three-proofing coating (5) is sprayed, so that the whole antenna is manufactured. The manufactured antenna has the advantages of being good in mechanical environment adaptability, high in conformal matching degree with the carrier and small in scattering area, and can be applied to airplanes or other mobile platforms with high requirements for stealth and aerodynamic performance.
