Abstract :
A Y-shape array, optimized for RFID backscatter-tag localization and identification in the UHF 869 MHz band, has been presented. The antenna-array element consists of a miniaturized slot antenna printed on a metallic box which, thanks to its non-resonant property, allows to keep an acceptable bandwidth while it lower the back radiation level and allows easy reconfiguration. Reducing the antenna thickness without reducing its occupied surface i.e. a slightly reduced radius of the sphere enclosing the antenna, does not drastically affect the antenna performances.
