A Simplified Method to Reduce Dimensions of Planar Passive Circuits Using Defected Ground and Defected Microstrip Structures

In this work, a simplified and accurate mathematical method to predict the reduced dimensions of microstrip circuits by using planes with discontinuities such as defected ground structures (DGS) and defected microstrip structures (DMS) is proposed. The...
The use of discontinuities in ground planes or in microstrip lines is currently employed to improve the performance of different passive circuits, such as the size reduction of amplifiers, 1 the enhancement of filter characteristics 2,3 and applications to suppress harmonics in patch antennas. 4 On the other hand,...
