Abstract :
A dual-band filter design using the epsilon-near-zero (ENZ) metamaterials (MTMs) is considered. A novel dual-mode resonator on combination of a substrate integrated waveguide (SIW) capacitively loaded cavity and a complimentary split-ring resonator (CSRR) etched on the SIW top cover is proposed. At the both resonant frequencies such a resonator behaves as an ENZ MTM. The resonator has a small size and suits well for the design of compact dual-bandpass filters with a low loss. Design of a dual-band filter for WLAN application is presented.
