Abstract

This paper presents the design and simulation of a slotted microstrip antenna which supports dual band operation. The proposed antenna covers upper WLAN [5.2 GHz (5.15-5.35 GHz) and 5.8 GHz (5.724-5.825 GHz)] bands. The substrate used is FR4 having a thickness of 1.6 mm and dielectric constant of 4.4 with a loss tangent of 0.02 is used. The designed antenna is compact in size having the size of the substrate as 40X50 mm. It is having two central frequencies at 5.194 GHz (5.11- 5.29 GHz) and 5.778 GHz (5.66- 5.8825 GHz) which achieves a bandwidth of 180 MHz and 222.5 MHz. It gives an improved return loss of -22.6852 dB and -16.697dB at 5.194 GHz and 5.778 GHz respectively. The designed antenna shows the directional radiation pattern at both the frequencies with acceptable front to back ratio and VSWR at these frequencies below 1.5.
