This paper presents microwave resonators and filters fabricated with uniplanar lines such as a coplanar waveguide(CPW) and slot line(SL). We focus on an open-ended λ/2 resonator, short-ended λ/2 resonator and λ/4 resonator for fabricating the bandpass filters(BPFs). Various BPFs based on these resonators are presented and their characteristics are also discussed.
