|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.|
