Abstract

A compact dual-band band-reject filter using complementary split-ring resonators is proposed. This complementary structure helps to expand the bandwidth or to design filters with multi bands. The centre frequency of the filter is at 6.05 and 7.14 GHz with the FBW of 11.1 and 11.3%, respectively. Good agreement has been obtained between simulated and measured results.
