AN IMPROVED LOW PASS FILTER USING MICROSTRIP DEFECTED GROUND STRUCTURE

Abstract – Defected ground structures (DGS) are of increasing importance in filter applications. We use the square head slots with certain parametric variations as the unit cell to design an improved low pass filter (LPF). The effect of variation of square head separation has been studied. Full wave simulator, IE3D has been used. The measured results show that the designed LPF has a cutoff frequency of 1.75 GHz and a rejection of at least 30 dB for over 8 GHz.
