The development of compact radio frequency identification (RFID) tag is the key requirement for wireless tracking of precious small size goods/packages in transport. A design of compact meander line tag antenna having inductive coupling feed is presented for RFID system operating at ultra high frequency band of865–867 MHz. The size of the proposed tag antenna is43 mm × 10 mm, and is designed using Higgs 4 IC chip (made Alien Technology, USA) having impedance of20.55− j191.45 Ωat centre frequency866 MHz.The antenna characteristics such as impedance, radiation pattern, bandwidth, and effect of ground on gain and tag size are analyzed and found to closely match with the simulated values. The observed value of reading range varies from87.5 to 35 cmsdepending on mounting on non-metal and metal packages, respectively.
