A novel HMSIW wideband bandpass filter
提出一种基于半模基片集成波导和缺陷地结构的新型宽带带通滤波器,将半模基片集成波导的高通特性与改进的哑铃形缺陷地结构的低通特性结合,实现了一种宽带小型化的带通滤波器.仿真与测试结果表明,该滤波器中心频率为5.3 GHz,相对带宽为53％,通带范围内插入损耗小于1.6 dB.该滤波器具有宽带小型化,容易集成等优点.
A novel wideband bandpass filter based on half mode substrate integrated waveguide (HMSIW) and defected ground structure is proposed in this paper. A compact wideband bandpass filter was realized by combining the highpass charac-teristic of half mode substrate integrated waveguide with the lowpass characteristic of the improved periodic dumbbell-shaped de-fected ground structure. The simulated and measured results show that the center frequency of the filter…查看全部>>
