Abstract: Three types of printed radio-frequency-identification (RFID) antennas with the characteristics of high gain, wide beam wave, and omnidirectional beam wave are constructed and evaluated in this study. The objective is to find out their best reading rates for providing effective wireless communications among RFID antenna readers during the library book inventory process. Three kinds of antenna readers have been fabricated on the printed circuit board (PCB) with the operating frequency at 915 MHz, which are tested by using vector network analyses device named Agilent PNA N5230A and simulated by using antenna design kit named ANSOFT HFSS. The fabricated antenna readers are embedded into different locations of bookshelves at the library of Cheng Shiu University in Taiwan. According to the experimental results, the designed prototypes of the antenna readers has the characteristics of the directional radiation pattern, wide beam wave, simple shape, good gain, low cost and easy to be integrated to the bookshelf. They can benefit administrating librarians with the capabilities of decreasing the library inventory processing time and reducing the possibility of the books being misplaced.
