- Abstract
- In this article, a compact tag antenna for UHF RFID systems is proposed. The proposed antenna consists of a T-matching. network, meandered dipole, and an inverted-U shaped parasitic element. The tag antenna is miniaturized by utilizing inductive coupling between the meandered dipole and the parasitic element. The overall dimension of the proposed tag antenna is 17.96 x 35.6 mm(2). It has a gain of 1.52 dBi and a maximum reading distance of 6.3 in at 915 MHz. The size of the tag antenna is about 33% of that of other RHO tag antennas, such as a meander line antenna and a coplanar inverted-F antenna. In spite of its small size, the proposed tag antenna yields superior performance. (C) 2010 Wiley Periodicals, Inc.
