CE 1.1: Project IntroductionName of the Project: Chip Impedance Matching for UHF RFID Tag AntennaDesignGeographical Location: [Please Fill]Project Duration: [Please Fill]Organization: [Please Fill]Position in the Project : Team MemberCE 1.2: Project BackgroundCE 1.2.1: Characteristics of the ProjectIn the recent days, the advancement of wireless technology has resulted in the increaseduse of RFID (Radiofrequency Identification) technology. In most cases, the RFID tags are usedfor controlling and monitoring various processes. Apart from that, the touch less and wirelesstechnologies used in various stores and banking sectors utilizes the RFID technology. Whileevaluating and studying about the wireless RFID tag antenna, I have observed the significantlimitation of the antennas is the smaller read range and the high power consumed for operations.Therefore, I took this project for increasing the read range while reducing the antenna size forproviding more compact antenna design. For maximizing the read range of the RFID, I havematched the impedance of the chip used in the RFID tag along with the impedance of theantenna used in the RFID tag. Page 1 of 9

CE 1.2.2: Objectives developed for projectIn this project I have aimed to increase the read range of the RFID tag antenna. For thedesign and analysis I have considered the use of UHF RFID antenna. In UHF RFID antenna, themicrochip antennas are integrated within the tag itself. For the increment of the read range of theantenna, I have observed that it is essential to match the impedance level of both the tag and theantenna integrated within the RFID tag. For the successful completion of the project, I havedeveloped the following objectives as follows:To determine the appropriate functional process used in RFID antennas;To match the impedance of the tag and the antenna integrated with the UHF RFIDantenna;To increase the read range of the RFID tag antennas;To integrate the COMSOL model for increasing the read range and matching theantenna impedance;To validate the proposed design of the antenna;To optimize the design of the RFID tag antenna;CE 1.2.3: My area of work I have studied various processes and working procedure of the RFID tag antenna. Inaddition to that, I have identified the various process and factors used in the RFID tag antennafor improving the read range and matching the impedance of the tag and antenna. Apart fromthat, I have identified the criteria and formula for matching the impedance and determining theread range of the antenna. Furthermore, I have used COMSOL Multiphysic for simulating thedeveloped antenna and proposed model. Page 2 of 9
