Abstract

A compact nonresonating, dual-band bandstop filter is proposed. By connecting two transmission lines with proper characteristic impedances and phase delay (one is 90° and the other one is 450° in electrical length at center frequency), a dual stopband with two transmission zeros at each stopband is obtained. A prototype is demonstrated for 2.4/5.8-GHz applications. The measured results show the dual fractional stopband bandwidths with 20-dB signal attenuation are 25.2% and 12.4%. Also, the theoretical simulation, electromagnetic simulation, and the measured results show good agreement with this simple design. © 2009 Wiley Periodicals, Inc.
