Abstract

See full text

A radio frequency identification (RFID) system includes an RFID interrogator configured for generating an RFID signal, wherein a channel frequency of the RFID signal changes over time; at least one single feed patch antenna; and at least one single feed line configured for feeding the signal to the corresponding at least one single feed patch antenna. The single feed patch antenna is configured to transmit an electromagnetic wave in response to and at the channel frequency of the RFID signal such that the electromagnetic wave exhibits (1) a polarization tilt angle that varies depending on the channel frequency of the signal, (2) a substantially linear polarization at all channel frequencies of the signal within the given operational bandwidth, and (3) a range of polarization tilt angles across the given operational bandwidth that spans at least 70 degrees within a single quadrant. A method for frequency multiplexing includes similar components.
