Microstrip Symmetrical E-Shape Patch Antenna for the Wireless Communication Systems

this paper represents designing & analysis of E- shape microstrip patch antenna for wireless communication. Low volume, low profile configuration, easily mounted, light weight, low fabrication cost is the advantages of this antenna. The operating frequencies of antenna are 3.1GHz and 3.45GHz, the substrate FR4 is used for proposed antenna which dielectric constant 4.2 and thickness of 1.6mm. Two parallel slots are cut to perturb the surface current path, which provides a bandwidth of 11%. The E-shape has return loss of -12dB of and -28dB at operating frequencies 3.1GHz and 3.45GHz respectively. Designing and simulation of this antenna has been done by the help of HFSS Software. This antenna is fed by a co-axial probe feeding. In this paper, the effects of different types of antenna parameters studied.
