In this study, the behaviour of coupled microstrip transmission lines loaded with complementary spiral resonators
(CSRs) is analysed in depth. CSRs are constitutive elements for the synthesis of metamaterials with negative effective
permittivity which allows the suppression of undesired signals at a given frequency band. Several test prototypes have been
characterised and modelled for transmission, crosstalk interference, isolation and signal integrity (SI). Experimental results
reveal that CSRs provide a good solution to reduce crosstalk between parallel transmission lines in the radio frequency band
with a low impact in terms of the SI. A design methodology based on the equivalent circuit model for the description of the
proposed structures, including transmission lines and coupling parameters, is provided. |
