THE CHARACTERISTICS OF THE BAND-PASS FILTER FROM THE VARIOUS PARAMETERS OF THE SUBSTRATE

Abstract

In this work, the design of a band-pass filter implemented on L-resonators is investigated. On one side of the substrate there are transmission lines responsible for the input and output of the structure. On the second side of the substrate are the resonators themselves. Studies have shown that to obtain a higher frequency band, a substrate with a high dielectric constant value is required. The thickness of the substrate affects the size of the filters. This filter is technologically easy to implement using standard methods of manufacturing printed circuit boards.
