摘要

作者阐述了折叠喇叭型天线的思想。与传统喇叭的主要区别在于其多点激励。在普通喇叭中，对于给定长度的喇叭，孔径尺寸的增加会导致其孔径内辐射场的二次相位变化。为了避开它们，长角是必不可少的。在折叠角中，通过多点阵型激励可以获得必要的同相孔径场分布。

Wide-band folding horn type microwave antennas

The authors illustrate the idea of a folding horn type antenna. The main difference from a traditional horn is its multipoint excitation. In ordinary horns the increase of aperture dimensions for a given length of the horn leads to undesirable quadratic phase variations of radiating field in its aperture. To avoid them a large length of the horn is essential. In a folding horn the necessary in-phase aperture field distribution is attained by its multipoint array type excitation.
