Abstract
This paper presents a planar ultra wide band filter employing chip inductors and complementary split ring resonators. Asymmetric interdigital coupled lines are used for achieving bandpass characteristics. Lower side transmission zeros are introduced using LC resonators consisting of chip inductors and circular patch capacitors. The filter has low insertion loss and flat group delay in its passband, steep roll off rate and good stopband attenuation. Measurement results for transmission and reflection characteristics of the fabricated filter are in good agreement with simulated response.
