This In order to meet the design requirements of airborne radar antenna, this article introduces the design and molding process of a dual-band UAV-borne radar compositematerial antenna. Thearticle proposed a kind of antennaunit which composed of skin, foam and microstrip antennas and carbon fiber, and a reflector with composite structure composed of foam, carbon fiber and stiffeners. The antenna and reflector are designed through an integrated process. A series of measures including the weight reduction and functional design of the antenna unit and reflector, the material performance is analyzed and optimized, and the mold design is adopted. It successfully developed a composite antenna with a size of 6000mm × 800mm × 20mm. After environmental test verification and a series of performance tests, the product is in good technical condition and meets the design requirements. This kind of composite material antenna has already been used on a type of drone, the drone has gone through flight test and the performance of the antenna is great. The successful development of this product can be used as reference for similar kind of UAV-borne radar antenna.
