Compact SIW-Based Multi-Mode Filters for High-Density PCB Integration

Abstract

This paper presents the design and analysis of compact Substrate Integrated Waveguide (SIW)-based multi-mode filters optimized for high-density PCB integration. The proposed filters leverage the advantages of SIW technology to achieve miniaturization and efficient multi-mode operation suitable for modern compact electronic systems. Design methodologies, simulation results, and experimental validation are discussed to demonstrate the effectiveness and feasibility of the proposed filters.
