Disclosed is a modular antenna panel including an antenna wire disposed in a panel substrate, and also including one or more electrical connectors and one or more mechanical connectors disposed at one or more edges of the modular antenna panel. The electrical connectors are configured for electrical connectivity with adjacent modular antenna panels and the mechanical connectors are configured to enable mechanical connections with adjacent modular antenna panels. Two or more modular antenna panels can be arranged to form an antenna assembly for a radio frequency identification system. Adjacent modular antenna panels are electrically connected to one another by engaging one or more of the electrical connectors disposed at one or more edges of the adjacent modular antenna panels, and are mechanically connected to one another by engaging one or more of the mechanical connectors disposed at one or more edges of the adjacent modular antenna panels.
