Parametric studies on effects of defected ground structure (DGS) for 6 GHz bandpass filter
Parallel coupled bandpass filter is proposed and designed by placing defected ground structure (DGS) in the ground plane. The proposed open loop dumbbell shaped DGS is used to tuned the bandpass filter to 6 GHz with a dimension of 50mm x 25mm. The bandpass filter is designed by using FR-4 printed ci...

| Summary: | Parallel coupled bandpass filter is
proposed and designed by placing defected
ground structure (DGS) in the ground
plane. The proposed open loop dumbbell
shaped DGS is used to tuned the bandpass
filter to 6 GHz with a dimension of 50mm x
25mm. The bandpass filter is designed by
using FR-4 printed circuit board and a
tuning range of 0.994 GHz is achieved. This
filter gives an insertion loss of -5.784 dB and
a return loss of -11.051 dB. A comparison of
the design of bandpass filter with open loop
dumbbell shaped DGS is analyzed to
identify the better performance of the
bandpass filter. The results of simulated and
measured filter is analyzed and discussed. |
