Performance of Micro Strip Patch Antenna for Dual Band Application

This research work presents analysis of dual band rectangular micro strip patch antenna for WLAN application. An antenna is design using FR-4epoxy substrate material with thickness 1.6 mm and dielectric constant 4.4. The proposed antenna has a compact size of 30 mm×30 mm and patch dimension 20 mm ×20 mm. The design antenna fed with coaxial feed technique. The simulated design antenna is operated at 5.4 GHz to 9.5 GHz, having resonating two different frequencies at 5.6GHz and 8.9GHz which is operated in C & X-bands. The rectangular Micro strip antenna have minimum return loss is - 21.44 dB at 5.6GHz and -27.68dB at 8.9GHz. In this antenna the maximum gain is 5 dBi at 8.9GHz and 3.75dBi at 5.6GHz respectively are achieved. The simulation of the design antenna is done using Ansoft HFSS software.
