Design of a triple band microstrip patch antenna for cellular and Wi-Fi application

This paper presents a design and simulation of a triple band microstrip patch antenna for cellular and Wi-Fi application. This will perform on the frequency 0.97 GHz, 1.35 GHz and 3.54 GHz. Ansoft HFSS software has been used for design and analysis. Before designing, the effect of frequency on length, width and the effect of dielectric substrate height on VSWR are analyzed. At 3.54 GHz the VSWR of this proposed antenna is -25.87 dB which clearly shows that this antenna will perform the best for Wi-Fi application. The proposed antenna having a compact size of 25 mm × 32 mm is simple and very easy to be integrated with microwave circuitry for low manufacturing cost. This microstrip antenna can also be made low profiled and conformal to fit on each individual platform, hence reducing or even eliminating antenna visual and radar signatures and increasing platform survivability significantly. The simulation also shows comparative differences between different feeding methods.
