Receiving and transmitting feed of reflector antennas for satellite communication systems

Abstract

The performance indicators of the antenna-feed path of a multiband reflector antenna are formulated and analyzed in the form of partial coefficients of the complex amplitude of the input signal, vectors of the polarization signal and noise in the input signal in each of the combined ranges. Examples of implementation of antenna-feed path multiband antennas based on various layouts are considered. Conclusions are drawn about the advantages and disadvantages of the presented methods.
