Simulation and Experimental Studies of a New Defected Ground Structure for Microstrip Lines at Ka-band
Keywords:
Defected Ground Structure (DGS); Microstrip Circuits; Ka-bandAbstract
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 26 GHz 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 stop band characteristics. The simulated results have been
validated with the measured data. Resonant frequency of stop band of the DGS can be varied from 28.2 GHz to
35.4 GHz.
