Abstract:
A method and apparatus are disclosed for improving RFID coverage using an antenna array having an adaptive antenna beam. The apparatus includes an RFID reader including an antenna array having a plurality of antenna elements. Subsets of the plurality of antenna elements are selectively activating in order to direct an antenna beam to communicate with at least one RFID tag. The method includes transmitting an interrogation signal from an antenna array by activating one or more subsets of a plurality of antenna elements forming the antenna array. In this way, the interrogation signal is directed thereby improving antenna coverage.

Claim (Index 16):
A method, comprising:\n activating a first subset of antenna elements of a plurality of antenna elements forming an antenna array to: generate a steerable antenna beam configured to transmit a first radio frequency identification (RFID) interrogation signal from the first subset of antenna elements, steer the steerable antenna beam towards a particular area within a monitored region, and interrogate at least one RFID tag; receiving, using a second subset of antenna elements of the plurality of antenna elements, a first RFID response signal from the at least one RFID tag in response to the first RFID interrogation signal; determining a signal quality of the first RFID response signal; in response to determining the signal quality of the first RFID response signal: changing the antenna elements in the second subset to a third subset of antenna elements of the plurality of antenna element; and activating the third subset of antenna elements to transmit a second RFID interrogation signal to again interrogate the at least one RFID tag to receive a second RFID response signal from the at least one RFID tag.
