Radio-frequency identification (RFID) system in management and administration of the books and documents has received much attention. A waveguide sheet developed by Teijin Limited is used as the reader antenna in RFID smart bookshelf system. For this system, it is desired that all of the RFID tags located on the waveguide sheet can be detected. The waveguide sheet with switched open/short termination has been proposed to increase the receiving level. In this report, switching diodes are used to terminate the sheet to realize the diversity receptions of the waveguide sheet.
