提出了一种聚焦扫描漏波天线。它是基于由场效应晶体管（fet）的精细级联连接制成的电子模式可调谐散射体的倏逝波散射。通过切换场效应管来调整焦点，使散射波的数量在目标点产生建设性干涉。我们的原型实现了2.4 GHz的聚焦扫描。所提出的天线可以作为一种非常低成本和轻量级的相控阵，特别适合于室内使用。
A focus-scanning leaky-wave antenna is proposed. It is based on evanescent wave scattering by electronically pattern tunable scatterers fabricated of fine cascade connections of field effect transistors (FETs). The focus is tailored by switching the FETs so that numbers of the scattered waves cause constructive interference at the target point. Our prototype achieved focus-scanning at 2.4 GHz. The proposed antenna can be used as a very low-cost and lightweight phased array especially suitable to indoor use.
