Abstract Additive manufacturing is an enabling technology for a wide range of applications, particularly within the domain of electromagnetism, where components and antennas can benefit from its use. The objective of this study is to design antennas with different effective permittivities using only a small number of dielectric materials that are compatible with additive manufacturing. A formalism based on the construction of macrocrystalline cells employing Bravais lattices is utilized to accurately analyze the homogeneity and properties of the materials. This formalism is then used to synthesize a specific effective permittivity with polymers or ceramics. Following experimental validation of the method, it was applied to the design of dielectric resonator antennas, which were then validated using measurements in C-band. This paper presents an original construction of a multipermittivity material based on the formalism outlined above. This development offers interesting possibilities for antenna designers.
