摘要

为了减小对足维瓦尔第天线(AVA)的交叉极化，采用基板集成波导(SIW)的TE20模式，在X波段上馈送两个具有相同振幅和相反相位的相对镜像复制的AVA。所提出的结构是平面的，并且由于它已经在SIW技术中实现，因此这种轻量化和低轮廓的天线在不希望的方向上具有低泄漏功率并且相对低成本。

Improving Co- to Cross-Polarization Ratio of Vivaldi Antenna Using TE20 Mode SIW Launcher

To reduce the cross-polarization of antipodal Vivaldi antenna (AVA), the TE20 mode of the substrate integrated waveguide (SIW) is used, which can feed two AVAs that are mirrored copy relative to each other with the same amplitude and opposite phase on the X band. The proposed structure is planar, and since it has been implemented in SIW technology, this lightweight and low profile antenna has low leakage of power in the undesired direction and is relatively low-cost.
