Design and Simulation of Meander Line Antenna for RFID Passive Tag

Abstract: Meandering is one of the methods in order to reduce the size of the antenna. By meandering we can reduce the size of the antenna by about 70%. The meander line antenna is designed using empirical relations and simulated in Advanced Design System (ADS). The meander line antenna is of size 10.2*9.2mm is designed in UHF (Ultra High Frequency) band using flexible polyester substrate with a dielectric constant of 3.5. The antenna is resonating at a frequency of 862.5 MHz with a return loss of -39.133 db.
