A review of substrate integrated waveguide (SIW) filter architecture and filter design technologies

Abstract

In this review article, transmission line technologies are compared in terms of loss, dimension, production cost, ease of integration and design complexity. The basic design stages of the Substrate Integrated Waveguide (SIW) filter, which stands out with its advantages among transmission lines, are given. Current studies using different SIW filter technologies have been examined in the literature. The quality factors of the examined SIW filters were calculated and a comparison was made between the applied techniques. In addition, the methods applied in the literature to eliminate the harmonic and high mode effects that adversely affect the SIW filter performance are examined and the results are evaluated.
