A broadband bandpass rectangular waveguide filter based on metamaterials

This paper presents a brand-new method and process of building a broadband bandpass filter in a flat rectangular waveguide with a passband between 6-12GHz (66.7% in percentage) using a 3-layer periodic SRR structure. Due to the unsatisfied reflection in the passband, another scale of SRRs have been...

Description
Summary:	This paper presents a brand-new method and process of building a broadband bandpass filter in a flat rectangular waveguide with a passband between 6-12GHz (66.7% in percentage) using a 3-layer periodic SRR structure. Due to the unsatisfied reflection in the passband, another scale of SRRs have been utilized as the lambda/4 impedance matching layer between the air and the metamaterial filter layer in the waveguide in order to decrease the reflection coefficient which is lower than -10dB after implement.
