Abstract
A lowpass filter with a very sharp rolloff factor of (70.18dB/GHz) , using modified defected ground structure (-DGS) and open circuit stubs is described. The lowpass filter was designed at a cutoff frequency of 2.67 GHz, which is suitable for GSM900, GSM1800 and UMTS applications of mobile communications. The proposed lowpass filter provides a size of 30x28x0.78 mm3, and have a good transition band with a good performance in the passband and it has a wide rejection band up to 11.0 GHz plus harmonic suppression in the stopband. Measurement results show good agreement with the simulated ones
