• 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
