Abstract :
The frequency selectivity that characterizes the response of resonant-type metamaterial transmission lines lend themselves to their applications in filtering devices. In this paper, it is demonstrated that Complementary Split Ring Resonators (CSRRs) can be used for the design of metamaterial transmission lines. The CSRR is used to design a microstrip stop-band filter for Ultra-Wideband (UWB) applications. In CSRRs the main driving mechanism is the electric coupling, and a significant component of the electric field parallel to the axis of the rings is required. So, by etching the CSRRs in the dielectric ground plane of a transmission line, in close proximity to the conductor strip, the required conditions for CSRR excitation are fulfilled.
