Here are the results of theoretical studies of microstrip multimode resonators with a short-circuited section of a strip conductor and ultra-wideband filter based on five-mode resonators. Electrical characteristics of microwave devices were obtained by means of numerical electrodynamic analysis of their 3D models. Substrates with dielectric constant of ε = 80 and ε = 9.8 were used in calculations. A synthesized filter with a 100% bandwidth has high frequency-selective properties and can be used in radio equipment of tropospheric and space communication with the advanced information transfer.
