摘要

提出了一种用于超宽带应用的增强辐射特性的对足维瓦尔第天线(A VA)。通过在天线孔径末端采用高介电常数的三角形定向器，在宽带应用中改善了指向性、波束宽度和相互去耦。为了实现结构紧凑、高增益和改善互耦，提出了1×4平面天线阵列。

Antipodal Vivaldi antenna array with high gain and reduced mutual coupling for UWB applications

An Antipodal Vivaldi antenna (A VA) with enhanced radiation characteristics for UWB applications is presented in this paper. By using of a triangular director with high permittivity in the end of the antenna aperture, the directivity, the beamwidth and the mutual decoupling are ameliorated over the wideband applications. In order to achieve a compact structure with higher gain and ameliorated mutual decoupling, 1×4 planar antenna array is proposed.
