Analysis of a Dual Band Microstrip Antenna

In modern wireless communication systems and increasing other wireless applications, wider bandwidth, multilane and low profile antennas are in great demand for both commercial and military applications. Since the micro strip antenna has its various advantages like low profile, small size, inexpensive cost and ability to be integrated with VLSI design. The current paper proposes a simple, methodical approach to design a micro strip antenna. Where the antenna behaviors are investigated. Simulation result of this antenna shows a dual band with little wider band width. From the return loss plot, it is concluded that a single antenna has two resonance frequencies, which are at 5.2Ghz and 7.69Ghz. Operating frequency of proposed antenna is 5.2 Ghz. Traditionally, each antenna operates at a single or multi frequency bands, where different antenna is needed for different applications. In addition to the theoretical design procedure, numerical simulation was performed using Methods of Moments and IE3D software.
