| Abstract: | An improved method in the design of the RFID reader is discussed.All of the hardware modules are introduced,and the software overall flow,anti-collision algorithm as well as the realization codes are given.Finally,some tests show that this method can enhance the working distance and the system sensitivity compared with the method based on a RF chip .The design has own-intellectual-property right.Practical applications indicate its good performance and stability. |
