Design and Simulation of E Slotted Square Shape Micro-Strip Patch Antenna for RFID Application

Communication between human's was first by sound through voice. With the desire for slightly more distance communication came, instruments such as drums, then, visual methods such as signal flags and fire signals were used. These optical communication devices, of course, utilized the visible light portion of the electromagnetic spectrum. It has only very recent in the history of the humankind that the electromagnetic spectrum, outside the visible region, has been employed for communication, through the use of radio. One of humankind's greatest natural resources is the electromagnetic spectrum and the antenna has been contributory in harnessing this resource.A Micro Strip Patch is three layer structures which consist of a radiating patch on one side of a dielectric substrate and has a ground plane on the other side This paper provides a detailed study of how to design and simulate coaxial -feed Micro strip Patch Antenna using IE3D software.In this paper we presents a proposeddesign and simulation of E slotted square shape micro strip patch antenna for RFID application which can be used for wireless communication such as RFID application. The radiating patch is square E slotted. The advantages of this is bandwidth enhancement, smaller in size, simple structure, low in cost and easy to be fabricated.In this paper, method of moments based IE3D software is used to design and simulate a E slotted Square Shape Micro strip Patch Antenna with better return loss, VSWR and enhanced bandwidth.Using proposed antenna design and coaxial feeding at proper position we find the resultant return loss, VSWR and enhance bandwidth. We are using IE3D software for designing and analysis. We have observed that using slotted patch antenna and using coaxial feed at proper location we can get better return loss, VSWR and wide bandwidth.
