新型高Q值U形缺陷地结构带阻滤波器
Novel high-Q band stop filter by using U-slot DGS
【摘要】 提出了一种新型的U形缺陷地结构(DGS)单元,该单元可以用来设计高Q值带阻滤波器。减小U形DGS结构两臂的槽宽及槽之间的距离,或在U形槽内加上贴片,可以增大Q值。最后用三个级联的U型DGS结构设计了一个高Q值的带阻滤波器,实验结果表明所设计的滤波器的Q值为35.3。
【Abstract】 A new defected ground structure (DGS) in the microstrip line was presented for the use in the design of high-Q band-stop filter. The Q factor increases rapidly when the slot width and the distance between the two slots decrease, or the conductor patch is embedded within the slots. By employing three cascaded U-slot DGS, a high-Q band-stop filter was designed and fabricated. Experimental result shows that the Q factor of the band-stop filter with three U-slot DGS is 35.3.
