We present a miniaturized dual‐passband filter module designed using double‐split complementary split ring resonator (DS‐CSRR) and split ring resonator (SRR). The use of SRR results in a significant size reduction of the filter comparing with edge‐coupled‐line filters. Two passbands are individually printed on two sides of a Rogers 3010 substrate, consequently providing a novel and compact integration. Coupling between two bands is weak, so they can be independently designed and tuned. Both bands operate at fundamental mode, providing an increased stability. A prototype dual‐band filter basic cell is fabricated and the measurement agrees well with simulations by Agilent's momentum. © 2008 Wiley Periodicals, Inc.
