Abstract
  In this paper, an ultra-wide stopband microstrip low pass filter with sharp roll-off and compact size is designed and fabricated. To provide very small dimensions, T-shaped and stepped impedance have been used. The cut off frequency at -3 dB is 3.1 GHz. In the proposed structure, the insertion loss is ...  Read More
