Design of a UHF / UWB monopole antenna integrated in an RFID reader board

In this study, we present a new circular monopole antenna with triple-band characteristics that can operate in both the ultra-high frequency (UHF) and ultra-wideband (UWB) bands and is integrated into a radio frequency identification (RFID) system reader module. In fact, the antenna was equipped with a patch and a CPW feed to meet the bandwidth specifications for RFID applications at UHF/UWB. To connect with RFID tags, this antenna is manufactured and inserted into the RFID reader board. Experiments show that the UHF-RFID efficiency of the monopole antenna is comparable to that of current commercial solutions.
