Design of a Substrate Integrated Waveguide Bandpass Filter Using in Microwave Communication Systems

摘要

Substrate-integrated wave-guide (SIW) which can be seamlessly integrated with planar circuits and more conveniently fabricated by normal PCB with low cost catches more and more scholars' attenuations and becomes a research hotspot in resent years. This paper presents a SIW band-pass filter designing steps with rectangular wave-guide resonator design method, that initial configuration parameters speed up the optimization process. There are good agreements between the experimental results and simulations.
