1. A method of forming an antenna for a radio frequency communication device, the method comprising:
- forming an antenna, a plurality of antenna segments and internal circuitry on a substrate for a radio frequency communication device; and
associating at least any two of the antenna and the plurality of the antenna segments by forming at least one of a fuse and an antifuse between the at least any two of the antenna and the plurality of the antenna segments,wherein, in the event that the at least any two of the antenna and the plurality of the antenna segments are associated by the fuse, the at least any two of the antenna and the plurality of the antenna segments are configured to be disconnected from each other in response to activation of the fuse, wherein the fuse is electronically activated in response to the internal circuitry, andwherein, in the event that the at least any two of the antenna and the plurality of the antenna segments are associated by the antifuse, the at least any two of the antenna and the plurality of the antenna segments are configured to be connected to each other in response to initiating the antifuse, wherein the antifuse is electronically initiated in response to the internal circuitry.

Abstract
A radio frequency communication device and methods of testing and tuning an antenna attached thereto are described. A radio frequency communication device comprises internal circuitry and an antenna having a plurality of antenna segments associated therewith. Each antenna segment is associated with the antenna in either series or parallel relation through at least one of a fuse and an antifuse. In testing and tuning, a comparison is made to indicate whether the antenna is too short or too long.

5. A method to form a radio frequency identification (RFID) tag, the method comprising:
-
providing a substrate; forming internal circuitry including an RFID circuit on the substrate; and forming on the substrate an antenna of the RFID tag, the antenna having a first segment and a second segment, the first segment being substantially short relative to the second segment, wherein the first segment is coupled to the second segment at a predetermined location for connection to the RFID circuit via the second segment, wherein a fuse is provided at the predetermined location to couple the first segment to the second segment; wherein, in response to the internal circuitry causing electronic activation of the fuse, the first segment is configured to become irreversibly disconnected from the second segment at the predetermined location to change a reception characteristic of the RFID tag. - View Dependent Claims (6, 7, 8, 9)
