摘要

本文提出了一种具有宽阻带的三通带通滤波器。该滤波器设计为1.8、2.4和3.5 GHz的三通带。1.8 GHz和2.4 GHz是通过控制非对称桩负载均匀阻抗谐振器(UIR)的阻抗和长度产生的，3.5 GHz是通过缩短均匀阻抗谐振器(UIR)产生的。通过使用非对称存根负载的UIRs，该滤波器具有封闭通带和宽阻带的频率响应，在3.7至12 GHz范围内阻带约为- 30 dB。实测结果与全波仿真结果吻合较好。

New Compact Triple-Passband Bandpass Filter with wide stopband

In this paper, triple-passband bandpass filter (BPF) with wide stopband is proposed. The filter is designed to have triple-passband at 1.8, 2.4 and 3.5 GHz. The 1.8 and 2.4 GHz are generated by controlling the impedance and length of the asymmetric stub-loaded uniform impedance resonators (UIRs) and 3.5 GHz is generated by shorted uniform impedance resonator (UIR). By using the asymmetric stub-loaded UIRs, the filter with closed passbands and frequency response of wide stopband having around −30 dB stopband from 3.7 to 12 GHz. The measured results are in favourable agreement with the fullwave electromagnetic (EM) simulation results.
