## Abstract A dual‐band microstrip bandpass filter with controllable bandwidth is proposed by using new dual‐band resonators. The resonator consists of a pair of shunt open stubs, including a stepped‐impedance open stub. The open stubs produce three transmission zeros, which result in sharp attenua
## Abstract In this article, a dual‐band bandpass filter (BPF) using the multilayered structure is presented. The BPF consists of a pair of uniform impedance resonators on the top layer and a pair of step‐impedance resonators on the middle layer. By using the multilayered structure, the multitransm
## Abstract A novel dual‐band bandpass filter is proposed in this article. Multiple stepped impedance resonators are shunt‐connected with the transmission line section to realize the dual‐band filter. Therefore, a transmission zero, which will increase isolation, can be easily generated in the midd
