## Abstract A novel wideband crossβcoupled bandβpass filter based on defected stepped impedance resonator (DSIR) is presented in this article. Although the DSIR has opposite impedance characteristic and field distribution to the microstrip SIR, its resonant property is similar to the latter. The in
## Abstract A novel lowβpass filter (LPF) is introduced in this article. The filter consists of a pair of feed lines with spurline resonators and a compact step impedance hairpin resonator. Because of the use of spurline resonators, the LPF exhibits better stopband characteristics and improved ripp
