Design and Characterization of E-Shape Microstrip Patch Antenna for Wireless Communication

The area of microstrip antennas has seen some inventive work in recent years and is one of the most dynamic fields of antenna theory. The ever increasing need for mobile communication and the emergence of newer technologies require an efficient design of antenna of smaller size for wider frequency range applications such as Wi-Max. The main aim of this paper is increase the impedance bandwidth of the microstrip patch antenna. A low profile wideband unequal E-shaped microstrip patch antenna for Wi-Max application is proposed in this paper .This proposed antenna is made by using the microstrip feeding method. Its bandwidth is further increased by introducing composite effect of stacking of patches with partial grounding. The antenna is designed and simulated by three-dimensional electromagnetic field software HFSS'12.The properties of the antenna such as bandwidth, S parameter, VSWR have been investigated.
