Novel Dual-band Bandpass Filter Using Multi-mode Resonator

摘要：

A novel dual-band bandpass filter using a multi-mode resonator is presented in this paper. Two passbands for WLAN bands are realized based on a multi-mode resonator with three open stubs. By appropriately selecting the characteristic impedance of the multimode resonator, the bandwidth of the two-order passband with even/odd-modes can be adjusted. In addition, the even/odd-modes frequencies can be controlled by the characteristic impedance of the multi-mode resonator, independently. A planar dualwideband bandpass filter prototype with 3-dB fractional bandwidths 22.8％ and 10.6％ is designed and fabricated. Good agreement between the simulated and measured results can be observed.
