Abstract :
This paper introduces an improved performance ultra-wideband bandpass filter by using lumped capacitors as an external coupling to stepped impedance DGS lowpass filter structure. The filter has a passband from 3.1 to 10.6 GHz and a wide stopband up to more than 20 GHz. Insertion loss less than 0.6 dB. The filter has a length of just 13 mm. The experimental results agree well with the predicted ones.
