Abstract: Nowadays, Radio Frequency (RF) was one of the main technologies in the world. This technique applied with tags was very famous and useful methods to do security control, access control or tracking system. In library, barcode was used a long time for check out the book but it could not do a tracking and circulation system to identify the book on the shelf. In this project, the main purpose was to design a tracking and counting system in library with RFID to reduce the time spending to find and count books. It checks the row of books and court the number of books in the shelf. There were installed four antennas in each row to detect the books. Each antenna was transceiver. They were enabled one by one based on the switching circuit to select the channel scanning the books. After the signal received, it would send to the computer for analysis. I am mainly focus on design the switching circuit and patch antenna. The switching circuit had two versions. The first one was simple switching circuit and another one was circuit with high isolation. Then I try to simulate the patch antenna using an edge feed method. The antenna could be operated in the radio frequency between 920MHz to 928MHz. I am also design the structure of the bookshelf.
