RFIDs in the UHF band are getting popular gradually in a lot of situations. Many kinds of small antennas have been contrived for UHF RFIDs. However, the antenna characteristics deteriorates in the case of using the antenna around water. In this report, a small cylindrical antenna was designed, which has little effect of water. The antenna is fed from an excitation loop outside of the radiation loop...
When passive RFID tags are used, RFID readers need to transmit a constant carrier, during uplink communication to provide sufficient operating power to the tag. This high power carrier with its associated noise, limits the receiver sensitivity and, hence, the possible reading range. This letter proposes a new way to cancel the received carrier. The topology, based on a directional coupler and a reflective...
