Asadbeigi, H. and Virdee, Bal Singh (2014) Compact notch filter design using stepped impedance resonators for sharp roll-off and large wideband rejection. International Journal of RF and Microwave Computer-Aided Engineering, 25 (6). pp. 490-494. ISSN 1096-4290

Abstract

This article presents the design of a compact notch filter with a sharp roll-off and high rejection over a wideband. The filter comprises stepped impedance resonators that are interconnected to each other at strategic points on the resonator for optimal 3 dB roll-off and high rejection over a wide stop-band. The fabricated third-order filter exhibits a steep 3 dB roll-off and rejection exceeding 50 dB over the frequency range 2.70–6.19 GHz.
