AN IMPROVED NARROWBAND MICROW AVE BANDSTOP FILTER Itzhak Shapir Microwave Technology Department, RAFAEL P.O.Box 2250 (87), Haifa 31021, ISRAEL ABSTRACT Capacitively coupled stub bandstop filters have excellent narrowband rejection performance at fa, but poor transmission characteristics in their upper passband, particularly around 2f0. An improved network, using capacitively loaded unit elements,
