摘要
采用波动理论方法分析了平面电磁波经点聚焦透镜天线会聚后焦斑大小和横向空间分辨率 ,得出了此类天线在会聚点的天线特性与平面口径天线在无穷远处的天线特性的关系 ,提出了透镜天线分辨率的一种测量方法。通过实测 。
The size of the focal area focused by spot focusing lens antenna and its transve rse spatial resolution are analyzed in virtue of wave theory in this paper. Rela tions between the characteristic of the spot focusing lens antenna at convergenc e region and the characteristic of the plane aperture antenna which brings the same field distribution at infinite region is obtained. The measurement of the lens antenna spatial resolution is brought forw ard. Measurement results are accorded comparatively with the theory calculations .
