摘要
本文以《星际迷航》徽章为基础，介绍了一种带有透镜和辐射侧腔的维瓦尔第反转天线（AVA），称为《星际迷航》侧边辐射天线（STSER-AVA）。其目的是改进参数，使拟议天线的辐射更具指向性。为此，开发工作的重点是减少中央辐射光束的斜视和侧叶电平（SLL），以及提高与传统 AVA 相比的增益。为了实现这一目标，我们采用了优化设计。在 3.90 GHz 频率下，带透镜的天线获得了更好的增益（9.42 dB），但与不带透镜的天线相比，SLL 降低了 -10.73 dB。这些结果是通过计算电磁模拟和实验测量获得的。
Antipodal Vivaldi Antenna with Star Trek insignia-based side slot edge for ultra-wideband applications
This article presents a Vivaldi Antipodal Antenna (AVA) with lens and radiating side cavities based on the Star Trek insignia, called Star Trek Side Edge Radiation (STSER-AVA). The objective was to improve parameters to make the radiation of the proposed antenna more directive. To this aim, the development is focused on reducing the squint of the central radiation beam and the side lobe level (SLL), as well as increasing the gain compared to a Conventional AVA. To achieve the objective, using an optimized design. The proposed antenna with or without a lens reached the target with a squint of -2.0 degrees, at 3.90 GHz the antenna with a lens achieved better gain (9.42 dB), but with a greater reduction in SLL of -10.73 dB compared to the lens less antenna. The results were obtained with computational electromagnetic simulations and experimental measurements.
