Abstract
In this work, we analyse the frequency response of
microstrip lines coupled by complementary split ring resonators
(CSRRs) etched on the ground plane supporting electroinductive
waves (EIWs). The single-particle configurations demonstrate the
principle of operation whose bandwidths reach 67% of the central
frequency. A double configuration is afterwards investigated as a
further improvement ...

In this work, we analyse the frequency response of
microstrip lines coupled by complementary split ring resonators
(CSRRs) etched on the ground plane supporting electroinductive
waves (EIWs). The single-particle configurations demonstrate the
principle of operation whose bandwidths reach 67% of the central
frequency. A double configuration is afterwards investigated as a
further improvement of the filtering response, such as the level of
the spurious lower frequency band. Finally, an ultimate prototype
comprising different CSRRs along the access line, together with the
aforementioned EIW-coupling is proposed for filtering undesired higher
bands. Experimental results confirm numerical analysis. [--]
