A dual-mode bandpass filter (BPF) using microstrip patch resonator is proposed. Open-stubs are added on the feed-lines to suppress the spurious response and improve the stopband rejection effectively with little increase in circuit size. Furthermore, a reduced-size dual-mode BPF with spurious response suppression using microstrip slotted-patch resonator is successfully designed. The simulated and measured results are presented and both are in good agreement. © 2007 Wiley Periodicals, Inc.
