A planar single improved dual-mode ring resonator loaded by four mushroom-shaped stubs based on a simple feed scheme is presented for design of dual- and tri-band bandpass filters (BPFs). The simple pair of feed lines with source-load coupling is used to not only feed the ring resonator but also generate the higher desired third passband when the length of feed lines changes. That is, a desired dual- or tri-band BPF can be designed based on the same single-ring resonator. For demonstration purpose, two experimental example filters have been fabricated and implemented. The simulated and measured results are presented and show good agreements. © 2014 Wiley Periodicals, Inc.
