Abstract

. This paper proposes a novel wideband, high-gain, compact Vivaldi antenna operating in the 14.7–20.5 GHz frequency range, where the antenna is fed by the substrate integrated waveguide (SIW). A Negative Index Metamaterial (NIM) has been designed, with its parameters extracted using MATLAB software. The NIM was developed to address the deficiencies of conventional Antipodal Vivaldi antennas. With a measured gain of over 5.3 dBi, the fabricated antenna performs satisfactorily across the entire bandwidth. Due to its low profile and short transversal dimension, the proposed antenna is suitable for antenna arrays; consequently, the proposed antenna design could be a viable option for modern communication and radar systems.

基板集成波导馈电的超材料负载对映维瓦尔第天线的增益和带宽增强

本文提出了一种工作在14.7–20.5 GHz频率范围内的新型宽带、高增益、紧凑型Vivaldi天线，其中天线由衬底集成波导（SIW）馈电。设计了一种负折射率超材料，并利用MATLAB软件提取了其参数。NIM是为了解决传统的反足维瓦尔第天线的不足而开发的。在测量的增益超过5.3dBi的情况下，所制造的天线在整个带宽上表现令人满意。由于其低轮廓和短横向尺寸，所提出的天线适用于天线阵列；因此，所提出的天线设计可能是现代通信和雷达系统的可行选择。

期刊介绍： Since 1992, the Radioengineering Journal has been publishing original scientific and engineering papers from the area of wireless communication and application of wireless technologies. The submitted papers are expected to deal with electromagnetics (antennas, propagation, microwaves), signals, circuits, optics and related fields. Each issue of the Radioengineering Journal is started by a feature article. Feature articles are organized by members of the Editorial Board to present the latest development in the selected areas of radio engineering. The Radioengineering Journal makes a maximum effort to publish submitted papers as quickly as possible. The first round of reviews should be completed within two months. Then, authors are expected to improve their manuscript within one month. If substantial changes are recommended and further reviews are requested by the reviewers, the publication time is prolonged.
