摘要：

The paper presents a manufacturing study of three-dimensional (3D) diamond electromagnetic band-gap (EBG) structures with a new manufacturing system. The EBG structures made from dielectric composites of alumina-slurry with 55 vol% Al2O3 powder were fabricated by means of a stereolithography (SL) and gelcasting system. The samples of the EBG structure of alumina-resin (before sintering) and that of alumina-air (after sintering) were investigated. The lattice constant was 12 mm, while the band-gap in the (110) direction appeared at 9.00-12.00 GHz, which agreed fairly well with the simulation results based on the finite element method (FEM) in Ansoft HFSS.
