摘要

近场测量表明，在不同光斑角的锥形角内插入圆盘所获得的指向性增强主要是由于孔径内电磁场的相位均衡。振幅变化没有特别改善，除非插入三个圆盘。

Near-field measurement of conical horns loaded with metallic objects

Measurements of the near-field indicates that the directivity enhancement obtained by the insertion of disc(s) inside conical horns of different flare angles are mainly due to the phase equalization of the electromagnetic field in the aperture. The amplitude variation is not especially improved, except when three discs are inserted.
