Defected ground structure technique to improve the frequency response of a microstrip lowpass filter

Defected Ground Structure (DGS), which is a simplified version of Electromagnetic Band Gap, has recently become popular in improving the frequency response of various passive components without sacrificing the overall size of the structure. However, such improvement is very much dependent on the size, shape, and position of the DGS.

In this webinar, we will show you, step-by-step, how to use the virtual prototyping high-frequency software, HFWorks, to improve the frequency response of a microstrip lowpass filter using a DGS.
