Abstract :
A small rectangular loop antenna (RLA) for RFID tags has been designed and fabricated for the UHF band. As the structure of a meander line and a folded meander line is applied in a general RLA, the RLA is miniaturised. The size reduction rate of meander line RLA and folded meander line RLA are 85.4 and 92.2% compared with a general RLA, respectively. The radiation patterns are omnidirectional in the z-y plane (horizontal pol.). Also the gain of the meander line RLA and folded meander line RLA are -2.47 and -4.01 dBd, respectively
