Patent ID: 6989796

Claim:
An antenna arrangement for use in connection with communicating with and identifying at least one identification element in operable communication with at least one object located in an enclosure having at least one “null” signal region, the antenna arrangement comprising: a primary antenna loop element positioned in operable communication with the enclosure and the at least one identification element positioned within the enclosure, the primary antenna loop element configured to communicate with the at least one identification element and receive a signal from the at least one identification element, thereby tracking the at least one object associated therewith; at least one feed point mechanism in communication with the primary antenna loop element and configured to at least one of energize the primary antenna loop element, transmit signals and receive signals; and at least one subsequent antenna element in operable communication with the enclosure and the at least one identification element positioned within the enclosure, the at least one subsequent antenna element configured to substantially eliminate the signal “null” region, such that at least one of the primary loop element and the subsequent antenna element can communicate with the identification element; wherein the subsequent antenna element is at least one subsequent antenna loop element positioned in a spaced relationship with the primary antenna loop element; wherein the at least one subsequent antenna loop element is vertically spaced from and substantially in alignment with the primary antenna loop element.
