A stepped impedance comb-line filter fabricated by using ceramic lamination technique

A filter named as a stepped impedance comb-line filter is proposed. The parallel stripline sections of stepped impedance resonators are coupled electromagnetically to form an attenuation pole. The design procedure for a two-pole planar filter is derived from an analysis using the even and odd-mode i...

Zusammenfassung:A filter named as a stepped impedance comb-line filter is proposed. The parallel stripline sections of stepped impedance resonators are coupled electromagnetically to form an attenuation pole. The design procedure for a two-pole planar filter is derived from an analysis using the even and odd-mode impedances. The experimental filters were constructed by ceramic lamination technique and they exhibited performances suitable for portable telephones.< >
