Abstract: Research on a directional coupler based on the offset irregular striplines by means of the electrodynamic simulation method is carried out. Selected method allowed to estimate the influence of geometrical parameters and feeders of the directional coupler on its frequency responses. Obtained outcomes showed that these responses are influenced by the higher order propagation modes and an air gap along the lines. The conclusion about what parameters should be taken into account when designing the mathematical model of the broadband directional coupler based on irregular uniform offset coupled lines is made.
