| Summary: | In wireless communications systems, harmonics and unwanted frequency other than
designed one becomes a dominant factor in limiting quality and capacity of transmitted
or received signal. Rectangular microstrip patch antenna (RMPA) is designed in order to
obtain the required parameter responses at 2 GHz. The proposed antenna is excited
through the microstrip feed line which is connected directly to the patch antenna. RMPA
of length 35.8462 mm and width 46.0721 is designed on the substrate dielectric material
FR-4 having dielectric constant r=4.3 and thickness 1.6 mm. The defect ground
structure (DGS) has gained much attention over the last few years for its ability to
increase the performance of wireless system by effectively suppressing harmonics DGS
shows a better result compared to the conventional antenna. It effectively suppressing
spurious frequency and reduces the amplitude of the unwanted multiple bands since the
antenna radiates only one resonating frequency. |
