| 摘 要： | 为了得到小型化的带通滤波器,该文提出了一种新的羊角形缺陷地结构(DGS),并将其与耦合开路枝节线结合,设计并制作了一种新型宽带带通滤波器。该带通滤波器的中心频率为7.95GHz,3dB通带为5.25~10.65GHz,相对带宽达到了68%。与以往的宽带带通滤波器相比,它具有结构简单,尺寸小的特点,仿真和测量结果吻合较好。

| Abstract: | In order to miniaturize the bandpass filter, a sheep horn defected ground structure (DGS) is proposed, and a novel wideband bandpass filter is designed and fabricated by combining the sheep horn DGS with coupled open stubs. The centre frequency of the filter is 7.95 GHz, and the 3 dB passband is 5.25 GHz to 10.65 GHz, the relative bandwidth reaches to 68%. This bandpass filter is simpler and smaller compared with previous wideband band pass filter. The measurement result agrees with the simulation result well. |
