Abstract
The disclosure relates to an antenna reflector phase correction film and a reflector antenna. The antenna reflector phase correction film includes a first substrate, a second substrate, and multiple artificial microstructures disposed between the first substrate and the second substrate, the artificial microstructures are wires made of electrically conductive materials, and an electromagnetic wave, emergent after being reflected by an antenna reflector attached with the antenna reflector phase correction film, has an equiphase surface. According to the disclosure, the antenna reflector phase correction film has specific refractive index distribution internally, so that a surface emergent phase of a reflector can be corrected after attaching onto a surface of a conventional reflector, a phase error caused due to installation or processing is improved, a complete flat emergent equiphase is obtained, and then a far-field performance (such as a higher gain) is improved.
