Abstract
A simulated and manufactured broadband antenna array of 2×2 meta-elements operating in the range of 2.5–4.5 GHz is presented. The characteristic size of the aperture of this sample is two wavelengths, but its realized gain exceeds 11.3 dBi in the entire range and reaches a peak of 14.3 dBi at the frequency of 3.2 GHz. Such results become possible by the successful combining electric and magnetic multipoles of the meta-elements, slightly spaced in frequency. As a trade off in accuracy and manufactring costs we use additive manufacturing: 3D printing of meta-elements on a photopolymer printer and subsequent metallization of their surface were involved in the manufacture of the antenna array.
期刊介绍:
This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
