摘要：

A compact dual-band microstrip filter with equal-length split-ring resonators and 0 degrees-feed structure is proposed in this article. The frequency splitting effect of the equal-length SRRs is described in detail. A 0 degrees-feed structure is introduced and applied to realize additional transmission zeros at finite frequencies. The measurement of the filter is in good agreement with the simulation. (C) 2008 Wiley Periodicals, Inc.
