A new UHF/ultra wideband‐radio frequency identification system to solve coexistence issues of ultra wideband‐radio frequency identification and other in‐band narrowband systems
Abstract:This paper presents a new Ultra Wideband‐Radio Frequency Identification (UWB‐RFID) transceiver to mitigate the coexistence issues of RFID systems and IEEE802.11.a WLAN or other narrowband (NB) systems. The UWB pulse used in the RFID tag is a frequency up‐conversion of the Gaussian pulse first derivative, which has a null in the frequency spectrum. The null is adjusted to be at the center frequency of the WLAN signal, mitigating the mutual interference between RFID and NB systems. In the receiving state, the pr… Show more
