Análises paramétricas de um filtro passa-faixa RSIW em banda S.

Abstract

With a growing demand for more efficient and highly optimized telecommunications systems, researches about the development and study of circuits that present these specifications have increasingly potential. In the context of high frequencies, more specific in microwave range, a technology has been standing out recently. SIW (Substrate Integrated Wave Guide) technology has advantages such as low irradiation rates, reduced manufacturing cost and high integration capability with other types of circuits. Among the variations of this technology, the present work focuses in the RSIW (Ridge Substrate Integrated Wave Guide) technology. Both technologies are applied in the development of various microwave devices, including antennas and filters. In RSIW technology, metal ridges are inserted into the structure and as a result, improvements in the filter bandwidth are achieved. Tthe present work presents a study and optimization of a microwave filter using RSIW technology, operating in the S band (2GHz - 4GHz). This filter will be reproduced and analyzed with simulations in ANSYSR÷ Electronics Desktop software.
