Abstract. The paper presents the results of theoretical and experimental researches of an ultra-wideband bandpass filter (UWB BPF) based on a multilayer strip-slot transition. Theoretical results are obtained in two ways: 1) by designing an equivalent circuit of the UWB BPF where each element is presented in the form of a two-port network with the corresponding matrix of A-parameters and 2) by numerical simulation in a rigorous formulation of the electrodynamics problem. Experimental results were obtained on a sample of the UWB BPF using a vector network analyzer. The results of theoretical and experimental researches are in good qualitative and numerical agreement. The investigated UWB BPF has a relative pass band at a level of -3 dB relative to the maximum transmission coefficient equal to 49,2% according to experimental research and 51% according to theoretical research.
Key words: bandpass filter, U-shaped strip resonator, U-shaped slot resonator, multilayer strip-slot transition.
