Abstract
A holographic antenna for recording a comprehensive interference pattern beyond the mere minimum and maximum values and reconstructing waveform of a target antenna includes a feed antenna and a holographic structure. The holographic structure includes a substrate and a plurality of spaced metal strips disposed on the substrate. Heights of the metal strips are negatively correlated with intensities of the interference pattern. A method for fabricating such a holographic antenna is also provided.

A holographic antenna for recording an interference pattern and reconstructing waveform of a target antenna, comprising a feed antenna and a holographic structure, the holographic structure comprising a substrate and a plurality of spaced metal strips disposed on the substrate, wherein heights of portions of each of the metal strips are negatively correlated with interference intensities of the interference pattern, portions of each of the metal strips having a height H1 are located on the substrate corresponding to a minimum intensity value T1 of the interference pattern and portions of each of the metal strips having a height H2 are located on the substrate corresponding to a maximum intensity value T2 of the interference pattern, remaining portions of each of the metal strips having heights H less than H1 but larger than H2 are located on the substrate corresponding to the intensity values T of the interference pattern larger than T1 but less than T2, the interference intensity values T, T1, and T2 and heights H, H1, and H2 of each of the metal strips satisfy the functions:
- 0≤H2≤H≤H1;
- and H=T×(T2−T1)/(H1−H2).
