AUTOMATED STRUCTURAL-PARAMETRIC SYNTHESIS OF A STEPSED DIRECTIONAL RESPONDER ON CONNECTED LINES BASED ON A GENETIC ALGORITHM

Abstract

An automated approach to the structural-parametric synthesis of a stepped directional coupler
on connected lines based on a genetic algorithm (GA) is described, which makes it possible to
create an algorithmic environment in the field of genetic search for solving NP complete problems,
in particular, the structural-parametric synthesis of a stepped directional coupler on connected
lines. The purpose of this work is to find ways of structural-parametric synthesis of a stepped directional
coupler on coupled lines based on the bionspiration theory. The scientific novelty lies in
the development of a modified genetic algorithm for automated structural-parametric synthesis ofa stepped directional coupler on connected lines. The problem statement in this work is as follows:
to optimize the synthesis of passive and active microwave circuits by using a modified GA. A fundamental
difference from the known approaches in the use of new modified genetic structures in
automated structural-parametric synthesis, in addition, a new method for calculating a stepped
directional coupler on connected lines based on a modified GA is righteous in the work. Thus, the
problem of creating methods, algorithms and software for automated structural synthesis of microwave
modules is currently of particular relevance. Its solution will improve the quality characteristics
of the designed devices, reduce design time and costs, and reduce the requirements for
developer qualifications.
