Abstract
An antenna for use with an RFID device reader includes a metallic plate and multiple antenna elements attached to the metallic plate. The antenna elements may consist of two prongs each, with the prongs of each element arrayed in a diagonal configuration, and with the two prongs forming an X-shape. Each of the prongs may include a pair of L-shape prong parts that are coupled together by an electrical element connecting the corners of the L-shape prong parts. The distal ends of all of the prong parts of the antenna elements may together form a substantially square shape. Each of the antenna elements may be coupled to a single conductor, for connection to an RFID reader. The connection may be through a suitable standard coupling, such as a coaxial cable with a suitable connector.
