Abstract

In this study, we present an ultra-wideband full-duplex system constituted of a wideband 4-element Vivaldi array and wideband microstrip-to-slotline baluns. The proposed system is characterised by its simplicity, high directivity, and high self-interference cancellation levels over a wide frequency bandwidth. The system is fabricated using basic printed-circuit board (PCB) technology and can provide at least 50 dB of self-interference cancellation over the bandwidth of operation, 4–40 GHz, with an average gain of 7.8 dBi. The system has a size of 8 cm × 8 cm × 9.4 cm and can be used as a high data rate link between two distant wireless nodes. To assess the merits of the proposed system and compare it to other published works, a new figure of merit (FoMWFD) dedicated to wide-band full-duplex antenna topologies is introduced in this study.

带内全双工应用的超宽带天线系统
在这项研究中,我们提出了一个由宽带4元维瓦尔第阵列和宽带微带-槽线平衡器组成的超宽带全双工系统。该系统具有简单、高指向性和高自干扰消除水平的特点。该系统采用基本印刷电路板(PCB)技术制造,在4-40 GHz的工作带宽范围内,可以提供至少50 dB的自干扰消除,平均增益为7.8 dBi。该系统的尺寸为8厘米× 8厘米× 9.4厘米,可作为两个远程无线节点之间的高数据速率链路。为了评估所提出系统的优点并将其与其他已发表的作品进行比较,本研究中引入了一个专门用于宽带全双工天线拓扑结构的新优点图(FoMWFD)。
