Abstract

Abstract : A compact wideband filter with a wide upper stopband using stub‐loaded multiple‐mode resonators is designed. The multimode behaviour and characteristics of the proposed filter structure are studied by conventional natural modes analysis. A prototype is designed and fabricated at 1 GHz ( f 0 ) with 3 dB fractional bandwidths 102% and 20 dB stopband attenuation up to 10.75 f 0 . Good agreement between simulations and experiments is observed.
