Bio-inspired intelligence for minimizing losses in substrate integrated waveguide

This paper presents a study of various types losses in substrate-integrated waveguides (SIW) using genetic algorithm. Three main are considered and examined separately: conductor loss, dielectric radiation loss. Furthermore, the current analysis allows for physical understanding loss impacts as well creation design guidelines to reduce at 10 GHz frequency while keeping miniaturized size SIW. Validation results obtained software Ansys HFSS, verify that attenuation constant SIW can be significantly reduced 0.4 dB/m, Insertion S21 -0.2 dB return -38 if geometric parameters chosen properly. enables us identify source and, result, eliminate any type dispersion. That demonstrates usability technologies microwave circuits used Internet things applications.
