Abstract :
A microstrip defected ground structure dual mode filter is presented. Several methods for coupling between the dual modes are investigated. Defected ground structure is used to enhance the external coupling and to introduce the necessary perturbation to the initially symmetrical structure. The proposed device is compact, requiring a surface area of about 6 times smaller than the area needed for a conventional patch dual mode resonator.
