INTRODUCTION


What is RFID ?


• An MSA in its simplest form consists of a radiating patch on one sideof a dielectric substrate and a ground plane on the other side.

• Various configuration of MSA shapes which involves square, circular, triangular, semicircular, sectoral and annular ring shapes are used to make MSA more efficient in RFID application.

• Implementation of Microstrip antenna in the design of RFID application.

• Various techniques and configuration are use to overcomes the disadvantages of microstrip antenna in RFID application.

INTRODUCTION

Literature Survey


• There are many technique are used to get the standard result, which include parameter : range of RFID, frequency, Bandwidth, directivity and Gain.

• Microstrip antenna having disadvantage of low Gain and narrow B.W, so different techniques is used to overcomes these drawbacks ,and that techniques having many own advantages and disadvantages.

• As one Example omega shaped antenna increases the range of RFID using metamaterial and it gives best return loss -10dB .[4]

Different configuration

• Configuration of antenna used for RFID: omega shapes , annular ring slot antenna , bow –tie , c-shaped, hybrid patch coupler, planar inverted-F antenna (PIFA).

• Characteristics : Gain, B.W., Power transmission, RL , Directivity.
