In this paper, a novel dual-band suspended stripline (SSL) filter is proposed. Based on traditional designing technique, a band-pass SSL filter is designed. Considering the unique properties of metamaterials, we apply it to the filter structure designing. Metamaterials can produce negative permittivity and thus there forms a dual-band. The simulated results exhibit low insertion loss, high selectivity...
A dual band frequency selective surface (FSS) based on circular aperture‐coupled patches is presented. The technique is based on using two same structures with different sizes. A special topology is proposed to arrange the two different sizes structures. Each structure is composed of two circular patches and a circular coupling aperture. The dual band FSS has a second‐order band pass responses at...
