Abstract

A novel fractal tag antenna constructed with Hilbert-curve and self-complementary configuration is proposed for UHF RFID applications. The main aim of this paper is to merge the meander line and meandered-slot structure of the RFID tag antenna in order to obtain a good performance of compact, broadband, circular polarization and conjugate impedance matching. The tunable inductive and broadband (-10 dB BW = 115 MHz) characteristics of frequency responses and directivity (1.62 dBi) as well as circular polarization (-3dB AR BW = 315 MHz) of radiation patterns for 900 MHz are studied and presented.
