Filter matching network; Substrate integrated Waveguide-SIW; Complementary Split Ring Resonators-CSRR.Abstract
This paper presents a novel method for creating a matching network (MN) with filtering functionalities on substrate intergrated waveguide (SIW) using Complementary Split Ring Resonators (CSRR). It defines principles for modifying the MN impedance through adjustments to the parameters of the CSRR and SIW transmission line. Additionally, it demonstrates the practical implementation of this approach by designing an output MN for a high-frequency power amplifier operating at 6 GHz. The MN is configured with dimensions of 13.6 x 5.4 mm and exhibits an insertion loss of 1.26 dB.
