The object of research is the antenna-feeder path of the RT-32 radio telescope for receiving signals with elliptical polarization
in the C-, K- and X-frequency bands. The aim of the work is to investigate the possibilities of modifying the dual-band antenna-
feeder path of the C- and K-bands of the RT-32 radio telescope to create a combined three-band path of the C-, K- and X-
frequency bands in order to jointly receive signals in these frequency bands. Create an electrodynamic model of the three-band
path of the C-, K- and X-bands and calculate the expected characteristics. Research methods are the methods of computational
electrodynamics and creation on their basis of fast algorithms of calculation of electrodynamic structures characteristics,
methods of optimization by means of software packages on the basis of grid methods of electrodynamics. In the work on the
first stage of research in order to expand the operating frequency range of the RT-32 radio telescope, the possibility of revision
the antenna-feeder path for receiving signals in the X-frequency range was investigated. Modeling of variants of construction of
a receiving waveguide path is carried out, the most perspective variant is revealed, the basic geometrical parameters of
waveguide elements are defined. The optimization of the elements of the path: low-pass filters, elements of coupling of circular
waveguides, devices for separating circular polarizations of C and X bands. It is indicated that for further improvement of
characteristics additional optimization with involvement of large computing resources is necessary.
