Abstract
A reader antenna for a radio frequency (RF) identification (RFID) reader operative for scanning RFID item tags that are oriented at different orientations and that are associated with items contained in a controlled area, includes a pair of mutually orthogonal dipoles for radiating electromagnetic waves with mutually orthogonal polarizations, an electrically energizable RF switch for switching between the dipoles, and an RFID antenna tag mounted adjacent the dipoles, and operative for receiving the radiated wave from either dipole, for locally generating electrical power to supply power to the RF switch, and for energizing the RF switch to switch between the dipoles.
