 In 2024, a software package was developed using the Python programming language for modeling the frequency characteristics of the transmission coefficients (S21) and reflection (S11) of bandpass, notch filters, antennas, and resonant structures of heterodyne devices built on microstrip resonator (MSR) and dielectric resonator (DR). The obtained frequency characteristics were subsequently used to synthesize prototypes of electrical circuits of filters, antennas, and resonant structures of heterodyne devices using AWR Microwave Office. Based on the obtained prototypes, simulation modeling of the topologies of printed circuit boards of the following microwave devices, both on individual MSRs and on combinations of MSRs and DRs, was carried out using the CST Studio software environment: 1) a two-resonator notch filter on MSRs; 2) a two-resonator 2.7 GHz bandpass filter on MSRs; 3) a two-resonator 4 GHz bandpass filter on DRs; 4) Rejector filter on a combination of MSR and DR in the 4.2 GHz range (an SSR resonator was used as an MSR); 5) Three-resonator bandpass filter with parallel electromagnetic communication channels on a MSR in the 2.8 GHz range; 6) Four-resonator filter in the 2.9 GHz range on a MSR (an SSR resonator was used as an MSR); 7) Dielectric resonator antenna in the 4 GHz range; 8) Rectenna based on an MSR antenna in the 2.4 GHz range; 9) Auto-oscillator (heterodyne) in the 4 GHz range with an resonant structure in the form of a combination of two SSR resonators; 10) Auto-oscillator (heterodyne) in the 4 GHz range with a resonant structure in the form of a combination of MSR and DR (an SSR resonator was used as an MSR). The requirements for the parameters of microstrip and dielectric resonators - resonant frequencies, overall dimensions, Q factor, dielectric permittivity - were determined. Using the resonator parameters obtained in the process of simulation, several groups of DR of cylindrical, rectangular and hemispherical shape were developed.
