提出了一种由共面波导（CPW）和共面带（CPS）组成的半模基片集成波导（HSIW）滤波器。在顶层金属层上刻蚀出四分之一波长共面波导和半波长共面波导谐振器，实现了扩展偶极子拓扑结构。同时，由于HSIW、CPS和CPW的高阶谐振频率不同，获得了宽阻带特性。最后，设计了一个HSIW滤波器，并进行了实测，S参数的实测值与仿真值吻合较好。
A half-mode substrate integrated waveguide (HSIW) filter incorporated with co-planar waveguide (CPW) and co-planar strip (CPS) is proposed. Quarter-wavelength CPW and half-wavelength CPS resonators etched on the top metal layer are used to realized extended-doublet topology. Meanwhile, wide stopband characteristic is obtained, which is due to different higher order resonant frequencies of HSIW, CPS, and CPW. Finally, an HSIW filter is designed and measured, good agreements are achieved between measured and simulated S-parameters.
