A novel compact microstrip low‐pass filter is proposed using defected ground structure and spurline. The measured passband to stopband attenuation slope is more than 73 dB/GHz. Electrical length of the filter is less than 20% of the guided wavelength at 3 dB cutoff frequency. Measured stopband attenuation is greater than 20 dB over more than 17.5 GHz band. © 2006 Wiley Periodicals, Inc.
