This latter demonstrates an accurate equivalent circuit for a negative permittivity resonator using single‐cell complementary split ring resonator underneath a microstrip line that introduces two attenuation poles in desired frequencies. The proposed equivalent circuit consists of lumped elements that can be accurately extracted from the measured S‐parameters. Good agreement with response of equivalent circuit, electromagnetic simulation, and measurement is demonstrated. © 2006 Wiley Periodicals, Inc.
