| Sumario: | [EN] This paper is focused on the design of bandpass filters based on open complementary split ring resonators (OCSRRs) in microstrip technology. The filters are obtained by coupling the corresponding shunt resonators (OCSRRs) through admittance inverters (quarter wavelength transmission line sections). Different undesirable effects derived from the chosen topology are taken into account and are compensated at the design level. These effects include the reduction in bandwidth (caused by the narrowband functionality of the line sections acting as admittance inverters), and the presence of a spurious band above the filter passband. The proposed technique is based on the well-known aggressive space mapping algorithm, which is a powerful tool for the synthesis and design of microwave components. The design of the OCSRR-based filter is provided in a fully automated way as the main result of this paper. Copyright (c) 2015 John Wiley & Sons, Ltd. |
