新型S形EBG结构的超宽带基片集成波导带通滤波器
A New Ultra-wideband Bandpass Filter of Substrate Integrated Waveguide(SIW) Based on S-shaped EBG
摘要
Abstract
A novel S-shaped electromagnetic band gap (EBG) ultra-wideband band-pass filter based on substrate integrated waveguide (SIW) is proposed.The filter is designed based on the band-stop characteristics of EBG and can obtain ultra-wideband by etching different dimensional S-shaped on the surface of substrate integrated waveguide.The designed band-pass filter with a center frequency as 9.03 GHz and relative fractional bandwidth 26.14％ shows good band-pass characteristics with the frequency band between 7.85～10.21 GHz while the insertion loss is less than 1.54 dB and still the designed filter has the advantage of narrow band-pass,low insertion loss,compacted and good selectivity etc.that's better than the results in the referrence[8～10].the good agreement between the measured results and the simulated results demonstrates that the design of this proposed filter is effective.关键词
