    Abstract

    A binomial low-pass filter provides the flattest pass-band response but slow attenuation transition. A design for improving the roll-off performance based on the negative-ε property of complementary split-ring resonators is presented, whilst maintaining the filter pass-band performance. By properly designing and integrating the complementary split-ring resonators with the low-pass filter, not only can the roll-off of the filter be significantly improved, but also the filter size further reduced. The measured results indicate that the proposed structure achieves a flat pass-band with no ripples as well as has a selectivity of 32dB/GHz. This significantly exceeds the 17dB/GHz selectivity of the conventional design. Furthermore, the proposed filter has a size smaller by 16. © The Institution of Engineering and Technology 2008.
