摘　　要：给出了一种采用枝节加载谐振器和缺陷地面结构实现的三通带滤波器。枝节加载谐振器采用交趾耦合实现了工作于2.45 GHz和5.25 GHz的两个通带,利用缺陷地面结构实现了工作于3.5 GHz的另一个通带,3个通带实现了独立设计。基于该方法,设制作了一个工作于2.45 GHz、3.5 GHz和5.25 GHz3个无线通信频段的三通带滤波器。实测和仿真结果对比验证了设计方法的有效性。A novel tri-band filter composed of stub loaded resonator （SLR） and defected ground structure （DGS） resonator is presented in this paper. The SLR with interdigital coupling forms two passbands centered at 2.45 GHz and 5.25 GHz, and the DGS resonator on the hack forms a bandpass response at 3.5 GHz, which have realized independent passband design. Based on this method, a tri-band filter operating at 2.45/3.5/5.25 GHz is designed, fabricated and characterized, whieh can be used in wireless communication. The simulated and measured results show good agreements and validate the proposed design method.
