Left-Handed Metamaterials for RF and Microwave Filter Miniaturization
Super compact microstrip line and CPW filters based on left-handed (LH) metamaterial medium for RF and microwave applications are presented and demonstrated by the full wave simulation and experimental results. The microstrip bandstop filter has a centre frequency of 1.164 GHz and a fractional bandwidth of 0.51%. The loaded quality factor of the filter is 197. The filter is more than 4 times smaller than that of the filter loaded with conventional transmission line. The CPW GaAs MMIC filter exhibits a broad passband from 6 GHz to 18 GHz with a size of 1.43 mm2.
