Abstract

Simulation and experimental results of a new type of Defected Ground Structure (DGS) for microstrip line at Ka-band have been discussed.The proposed modified square slot DGS exhibits single stop band in frequency range from 26GHz to 40 GHz.There are many published works on DGS up to K-band but DGS performance in Ka-band has to be explored. Thus, stop band effect of a new DGS has been studied for microstrip line at Ka-band. Variation in DGS dimensions changes the stopband characteristics. The simulated results have been validated with the measured data.Resonant frequency of stop band of the DGS can be varied from 28.2GHz to 35.4 GHz.
