Abstract：The 4-pole microwave filters using dual-mode meander suspensive strip line loop resonators have been developed. The results of the full wave analysis of the filters have shown that 4-pole filters have better performance than the 2-pole fiilters of same type. A 4-pole filter of this type on εr= 2.8 Teflon substrate having a bandwidth △f=19.4MHz at the central frequency f0 = 1.194GHz was designed and fabricated. The measured filter performance was compared with the prediction of CAD tool. The agreement was found to be good.
