Patent abstract
Radio Frequency Identification (RFID) readers with a directional coupler. At least one embodiment of the present invention provides an RFID reader designed to use a directional coupler to receive signals from an antenna which is connected to a radio frequency source of the reader to transmit signals. The directional coupler samples the signals received at the antenna and provides the received signal to a receiver of the RFID reader. In one example, the receiver of the RFID reader compares a portion of the signals from the radio frequency source with the received signal from the directional coupler to receive data from RF tags.
