Abstract :
The bandstop characteristic of a slot-type split-ring resonator (SRR) on a substrate used for microwave frequencies is presented for a bandstop filter. Analogously to the conventional strip-type SRR, the slot-type SRR is very attractive for notching unwanted band because of its small dimension and high Q operation. In addition, the complementary SRR can be easily applied for coplanar configuration, which is favourable to MMIC designs. Based on the simulation and measurement results, the slot-type SRR for the bandstop filter is very effective in rejecting unwanted frequency in terms of its selectivity and size.
