Paper Title:
A New Design of RF Tag Location and Recognition
  Abstract

In RF applications, tag orientation and collision that occurred when reader identify many tags at the same time are the main problems difficult to be solved. Identification and positioning to tags will be the main application in the further too. To solve the problem, a variety of algorithms have been proposed and obtained many good results. This paper gave a new idea to solve the problem from the tag side rather than algorithm, the main method is to add some transistors to the tag circuit. The circuit can supply high accurate location information to tags and then assist the reader to know their location; in tag identification the circuit can help part the tags in several groups according their different position. In the groups using corresponding grouping algorithm can enhance the anti-collision efficiency. The simulations in this paper have improved the added circuit is helpful to the accuracy of tag orientation and efficiency of multi-tag identification. From the detail redesign scheme we can conclude there is almost no increase in costs for the improvement of tags and the production process is easy, having well economic and feasibility.
