In this paper, filters implemented by combining open split ring resonators (OSRRs) and open complementary split ring resonators in a composite right/left handed line configuration are pointed out. The relevant aspect of the approach is that it is possible to implement standard responses (Butterworth or Chebyshev) with broad bandwidths. Also, due to the small electrical size of the employed resonators, the filters are very compact.
