High precision, high efficiency, and high gain
The most important job of using SMC for the manufacture of antennas is to fully exploit its features and achieve high precision in antenna design from product design and process. Under the condition that the shrinkage ratio of the material and the SMC molding shrinkage rate have been considered in the mold size design, the SMC antenna reflective surface has a smaller shape from the original design paraboloid after molding. That is, the accuracy of the SMC molded antenna is completely guaranteed by the accuracy of the mold. The rms value of the SMC antenna molded integral reflection surface is 0.25 mm, and the rms value of the single-piece reflection surface of the split antenna is less than 0.3 mm, and the rms value of the reflective surface after assembly is less than 0.6 mm.
