摘要

提出了一种模拟制造的2x2元元宽带天线阵列，工作频率为2.5-4.5 GHz。该样品的孔径特征尺寸为两个波长，但其实现增益在整个范围内超过11.3 dBi，在3.2 GHz频率处达到峰值14.3 dBi。这种结果是通过将元元素的电和磁多极成功地结合在一起而成为可能的，这些元元素的频率略有间隔。为了权衡精度和制造成本，我们使用了增材制造:在光聚合物打印机上对元元素进行3D打印，随后对其表面进行金属化，这涉及到天线阵列的制造。

Broadband antenna array realization with printed meta-elements and its multipoles spectra

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.
