Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description2 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 second stage of research an additional optimization of the filters of the lower frequencies was carried out with the method of suppressing the high-frequency modes, which are arise in the high-frequency paths of the С- and X-ranges. The additional optimization of the geometrical characteristics of the elements of the antenna-feeder path at the C-, X- and K-ranges was carried out. On the basis of the electrodynamic model, the theoretical drawings of the combined C-, X-, K-bands antenna-feeder path are developed.
