Project on Coefficient of Reflection Power for Antenna_1

CE 3.1 Project InformationName of the project: Chip Impedance Matching for UHF RFID Tag AntennaDesignLocation of the project: [PLEASE FILL]Project Duration: [PLEASE FILL]Organization: [PLEASE FILL]Role and Designation: [PLEASE FILL]CE 3.2 Project BackgroundCE 3.2.1 Characteristics of the projectIn recent days the automatic wireless technology of passive RFID (radio frequencyidentification) are used for collecting the data and transmitting the modulated signals to the tagsused with the RFID technology. I have observed that the RFID systems are developed withintegrated circuit chip and an antenna. The antenna powers the hip used in the system and thechip in turn responds with variation in the input impedance. Therefore, I have found that the datais being modulated with the application of backscattered signals. Orientation sensitivity andmaximum range are found to be significant characteristic of RFID technology. Apart from that, Ihave observed that for achieving the maximum effective operational condition, the impedance ofthe antenna needs to be matched with the accurate impedance of the chip. Therefore, the receivedpower needs to be equal to the frequency of the chip. In this project, I have focused onPage 1 of 11

calculating the coefficient of reflection power for antenna while calculating the antennaimpedance and chip impedance. CE 3.2.2 Objectives developed for the projectThe match of Impedance between the RFID tag and the antenna directly impact theperformance of the RFID system. In this project I have aimed at matching the impedance forRFID tag antenna. In this project I have proposed a advanced design of the antenna withenhanced read range and performance through Impedance Matching. In order to efficientlycomplete the project implementation and design I have formulated the below mentionedobjective:To identify the impedance matching characteristic of the RFID tag antenna;To match the impedance between the tag and the antenna module;To enhance the performance of the RFID tag antenna;To increase the read range of the RFID tag antenna;To simulate the developed designed antenna using HFSS software; CE 3.2.3 My area of workFor the design of the RFID tag antenna I was associated with the project as a team leader.I have reviewed various papers and articles based on the impedance matching of the RFIDantenna. After the evaluation, I was able to identify the working module required for this project,I have discussed the project plan with my team members and demonstrated the work with them.In addition to that, I have carried out the practical implementation and design of the antenna.
