Abstract
A method to design microstrip low pass filter having defected ground structure (DGS) is proposed. The difference between standard asymmetric microstrip technique and DGS is in using the structures etched in the microwave substrate ground plane. The DGS resonant characteristics are then used in filter design. The equivalent circuit for the proposed defected ground unit structure is derived by means of three-dimensional field analysis methods. The equivalent-circuit parameters are extracted by using a simple circuit analysis method. Filters of various orders and resonator configurations are designed and simulated. A combination of the DGS and five order low pass Chebyshev microstrip filter is designed as well realized and measurement results are compared with simulations. The experimental results show excellent agreements with theoretical results and the validity of the modeling method for the proposed defected ground unit structure. Finally, enhanced cut off frequency 2.715GHz of microstrip low pass chebyshev filter using DGS is observed.
