Abstract

In this paper we proposed compact size microstrip filter using hexagonal with transmetal Defect Ground Structure (DGS). Here, we have studied the response of five different types (square, circular, triangular, hexagonal & hexagonal with transmetal) of dumbbell shape DGS having same resonant frequency, and compare the response of different shapes DGS. It is observed that proposed DGS have more sharp cutoff frequency, quality factor as well as sharpness factor and occupying area of the proposed DGS is less as compare to other.
