Abstract
This work proposes the utilization of a high gain and pencil beam RefectArray (RA) antenna at the reader of
the Frequency Coded (FC) chipless RFID system to minimize the environmental reflections and increase the
reading range. Moreover, the reader antenna should operate over UWB range of frequencies to accommodate
multiple bits. However, the conventional antenna arrays can not operate over Ultra Wideband (UWB) range of
frequencies with high gain and pencil beam characteristics. Therefore, a novel UWB RA antenna dedicated to
the chipless RFID reader is developed. The developed RA antenna operates over UWB range of frequencies from
4 to 6 GHz to fulfill the requirements of the FC chipless RFID system. Therefore, the antenna is successfully
integrated with the FC chipless RFID tags, and a reading range of 1 m is achieved.
