摘要
提出了一种新型的耦合开环形组合式非周期缺陷接地结构(CNPDGS),该结构具有很好的双阻带特性,可用来抑制高次谐杂波,从而展宽阻带.利用有限元法研究了CNPDGS结构单元的尺寸对其传输特性的影响,并用该结构设计了一个截止频率为2.4 GHz的低通滤波器,其传输特性进一步验证了该CNPDGS结构的优越性.
This paper presented a novel combinatorial non-periodic defected ground structure （CNPDGS） and its application in the lowpass filter. The presented CNPDGS can provide the bandgap characteristic with dual-stopband. The influences of lattice dimensions on the characteristic of frequency were studied, The lowpass filter formed by microstrip and proposed CNPDGS was designed. The simulated results prove that the designed lowpass filter can effectively reject the higher harmonics.
