<P>PROBLEM TO BE SOLVED: To provide a kind of a radio frequency identification positioning apparatus and a method thereof. <P>SOLUTION: A kind of the radio frequency identification positioning apparatus and the method thereof are provided for identifying and positioning at least one radio frequency identification tag. The apparatus includes an oscillation module for oscillating a predetermined frequency, a capacitor, sensing modules, an identification module and circuit modules. A first switching unit of the sensing module performs a conduction operation according to the predetermined frequency to form a magnetic flux of an induction coil and the capacitor, such that the first induction coil senses an identification signal and a second induction coil enhances magnetic flux quantity. The identification module receives the identification signal for identifying and positioning a radio frequency identification tag. Each circuit module is connected to the oscillation module, sensing module, capacitor and identification module, and transmits the identification signal. The circuit modules have substantially equal length to achieve an electrically matched status of all induction coils. <P>COPYRIGHT: (C)2009,JPO&INPIT |
