Systems and methods for a reconfigurable antenna
First Claim
1. A device comprising:
- a plurality of antenna elements configured to read a radio-frequency identification (RFID) tag;
a switch having an input configured to receive an RFID control signal from an RFID reader via a communication line to select one antenna of the plurality of antenna elements; and
a controller configured to control a state of the switch,wherein the switch is configured to be switched between states when the controller receives the RFID control signal comprising an address unique to the controller, thereby allowing the RFID reader to send an interrogation signal to and receive a response from the RFID tag in response to receiving the RFID control signal.

Abstract
Systems and methods for a reconfigurable antenna are provided. One system includes a device having a plurality of antenna elements configured to read a radio-frequency identification (RFID) tag and a switch having an input configured to receive a control signal from an RFID reader via a communication line to select one antenna of the plurality of antenna elements. The device further include a controller configured to control a state of the switch, wherein the switch is configured to be switched between states when the controller receives the RFID control signal comprising an address unique to the switch, thereby allowing the RFID reader to send an interrogation signal to and receive a response from the RFID tag in response to receiving the RFID control signal.

10. A system comprising:
-
an RFID reader; and a reconfigurable antenna configured to couple to the RFID reader, the reconfigurable antenna having an antenna characteristic that is changed based on an RFID control signal received from the RFID reader, the reconfigurable antenna configured to appear as an RFID tag to the RFID reader, wherein the RFID control signal comprises an address unique to a controller in the reconfigurable antenna, wherein the controller is configured to change antenna characteristic of the reconfigurable antenna. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for controlling an antenna, the method comprising:
-
sending an RFID control signal from an RFID reader to a reconfigurable antenna via a communication line, the RFID control signal comprising an address of a controller in the reconfigurable antenna; switching a state of the reconfigurable antenna to change an antenna characteristic of the reconfigurable antenna in response to determining that the address in the control signal matches an address stored in memory of the controller of the reconfigurable antenna; and sending an interrogation signal to an RFID tag via the antenna of the reconfigurable antenna and receiving a response from the reconfigurable antenna after the switching is performed. - View Dependent Claims (20)
